Essay on earth is a unique planet

In the spring and fall, each hemisphere receives similar amounts of light. On two specific dates each year—called the equinoxes—both hemispheres get illuminated equally. About 4. Over time, Earth's interior—which is made mostly of silicate rocks and metals—differentiated into four layers.

At the planet's heart lies the inner core, a solid sphere of iron and nickel that's miles wide and as hot as 9, degrees Fahrenheit. The inner core is surrounded by the outer core, a 1,mile-thick band of iron and nickel fluids. Beyond the outer core lies the mantle, a 1,mile-thick layer of viscous molten rock on which Earth's outermost layer, the crust, rests.

On land, the continental crust is an average of 19 miles thick, but the oceanic crust that forms the seafloor is thinner—about three miles thick—and denser. Like Venus and Mars, Earth has mountains, valleys, and volcanoes. But unlike its rocky siblings, almost 70 percent of Earth's surface is covered in oceans of liquid water that average 2.

These bodies of water contain 97 percent of Earth's volcanoes and the mid-ocean ridge , a massive mountain range more than 40, miles long. Earth's crust and upper mantle are divided into massive plates that grind against each other in slow motion.

As these plates collide, tear apart, or slide past each other, they give rise to our very active geology. Earthquakes rumble as these plates snag and slip past each other. Many volcanoes form as seafloor crust smashes into and slides beneath continental crust. When plates of continental crust collide, mountain ranges such as the Himalaya are pushed toward the skies. Earth's atmosphere is 78 percent nitrogen, 21 percent oxygen, and one percent other gases such as carbon dioxide, water vapor, and argon.

Much like a greenhouse, this blanket of gases absorbs and retains heat. On average, Earth's surface temperature is about 57 degrees Fahrenheit; without our atmosphere, it'd be zero degrees. In the last two centuries, humans have added enough greenhouse gases to the atmosphere to raise Earth's average temperature by 1. This extra heat has altered Earth's weather patterns in many ways. The atmosphere not only nourishes life on Earth, but it also protects it: It's thick enough that many meteorites burn up before impact from friction, and its gases—such as ozone—block DNA-damaging ultraviolet light from reaching the surface.

But for all that our atmosphere does, it's surprisingly thin. Ninety percent of Earth's atmosphere lies within just 10 miles of the planet's surface. We also enjoy protection from Earth's magnetic field, generated by our planet's rotation and its iron-nickel core. This teardrop-shaped field shields Earth from high-energy particles launched at us from the sun and elsewhere in the cosmos.

But due to the field's structure, some particles get funneled to Earth's Poles and collide with our atmosphere, yielding aurorae, the natural fireworks show known by some as the northern lights. Earth is the planet we have the best opportunity to understand in detail—helping us see how other rocky planets behave, even those orbiting distant stars.

As a result, scientists are increasingly monitoring Earth from space. NASA alone has dozens of missions dedicated to solving our planet's mysteries. At the same time, telescopes are gazing outward to find other Earths. Thanks to instruments such as NASA's Kepler Space Telescope, astronomers have found more than 3, planets orbiting other stars, some of which are about the size of Earth , and a handful of which orbit in the zones around their stars that are just the right temperature to be potentially habitable.

Other missions, such as the Transiting Exoplanet Survey Satellite, are poised to find even more. All rights reserved.

Climate change goals and oil production are clashing in the U. Jupiter acts like a giant broom, sweeping the solar system of debris? This protective effect was particularly helpful in the solar system's early years, when Earth still got pummeled but, scientists say, not nearly as bad as would have been the case without Jupiter. Earth's moon stabilizes our planet's rotation, preventing drastic movements of the poles that could cause massive changes in climate that some scientists think could have doomed any chance for budding life to form or evolve.

The moon also helpfully pulls the ocean's tides, which scientists suggest might have been the perfect place for early life to begin evolving to survive on land. Though Earth has the necessary ingredients for life, it's unclear whether the development of life here might have been a one-time fluke, or if it's something that happens pretty much everywhere the conditions are right.

And Titan, when the [Huygens] probe landed, there was all this stuff in the media about how Earth-like it is. It is completely different. It has all this methane on the surface. Venus has about the same mass [as Earth], almost the same distance from the sun. But it?

Of the nearly new worlds glimpsed elsewhere in the galaxy, most are "hot Jupiters"? As our planet-hunting technology improves, many planet hunters expect to find Earth's twin. The search has led scientists to debate whether Earth is really as special as we think it is. Boss and many other scientists think it's likely that some form of life exists on some of those countless other planets out there. I think we're going to find there are literally billions of them in the galaxy. Join our Space Forums to keep talking space on the latest missions, night sky and more!

The human approach to growth and prosperity has always turned a blind eye to the environment and its replenishment. Such consciousness has been considered as a domain of activists and a hurdle to the growth process. Mahatma was accurate in his observation and the visionary could predict the direction of human progress. The lesser mortals even failed to follow his advice.

Sustainability in the use of resources has been neglected by one and all. Sustainable development is the crying need of the hour for ensuring the future of humanity on this planet. The understanding has to dawn that we have delayed the efforts already, as global warming knocks on our doors. It is only one of the signals from nature, that the time to act sensibly is imminent and ticking away.

A glance at our growth story will showcase a myriad of potholes. The process has widened the gulfs in our society and alienated segments from reaping the fruits of development. It has turned a blind eye to the deletion of fossil fuels and the heavy accumulation of greenhouse gases. It is time to switch over to sustenance in our activities and in our attitude.

The melting glaciers, erratic rainfall patterns, threats of disappearing nations by a rising sea level and increasing regularity of diseases is for real. It is disturbing enough to shake us out of our slumber and instill a mission-mode readiness in our efforts.

A determined global effort is needed to shift to the use of a renewable energy regime. An environment-friendly and sustainable regime is needed which will not add a burden on the future generations for our deeds. Sustainability does not come at the price of growth and development and human endeavor can deliver them simultaneously.

They can coexist and enrich each other to the benefit of coming generations. A major breakthrough in our efforts can happen only if we adopt an attitudinal change. Resources should become a perpetual tool and not exhaustible reserves if the development is pragmatic.

Such efforts would require the involvement of people at every stage of planning, execution, and evaluation and a paradigm shift is essential in our centrally dictated use of resources and sense of ownership could infuse miracles and bring about a turnaround in the conservation of resources for the future generation. With a sense of ownership, responsibility towards the use of resources will be generated.

The tribal will be integrated into forest management and fishermen as coastal eco-force. While each citizen will develop an energy-efficient outlook, every farmer will take care to enrich fields. The participation of people will accelerate the pace of efforts that appear isolated and insufficient when planned by the authority. This does not abdicate the state of its responsibility. It, rather, becomes more relevant and the crusade has to be carried proactively by the State.

The land resource sustenance has to be integrated with forest protection, conservation, and promotion. Efforts like social and urban forestry have multifarious dimensions and transmit multiple gains to society. Such programs have to be integrated with the lives of the population by percolating them to the grassroots. Sustainable agriculture could strengthen the backbone of weakening food security.

Proper planning of land use with dedicated grazing fields, bio-fertilizers and manures, natural pests as pesticides, and making each drop of irrigation water count can deliver better returns from our efforts to maintain the fertility of our land resources. The shift from demand-based to region-specific needs to be appreciated to develop each region holistically on its strength.

Monetary value to every careless act of polluting the natural resource may heighten the awareness of these growth seekers. The plantation can be promoted by industries as part of their social responsibility. Proper waste management system for cities with planned landfills or incineration plants is a must as urbanization is the order of the day; sustainable cities can become gateways for long term growth. Water harvesting through rooftop systems and pollution check of vehicles would ensure a greener environment and availability of water for future generations.

Slums that stand out for their poor hygiene and irreverence towards ecology — must receive a holistic up-gradation plan. Yet another tool is Environment Impact Assessment, which should become a mandatory organ of any development scheme. It is an anticipatory and preventive effort, which utilizes multidisciplinary knowledge to predict and prevent the damages that a development project may bring along. This tool would promote the simultaneous march of sustainability with ecology.

The lopsided approach of the human march on this planet has raised issues of his own survival. It has been an act of hara-kiri. The development of the resources should be a democratic process for and by the people. Each region has unique variables and each should be strengthened to find its own sustainable solution.

It calls for recognition of local, traditional, and indigenous wisdom. The problem of securing a better future for coming generations is a genuine and real concern, where the onus is on each one of us. The effort has to come not only at global organizations but through actions of every individual as we strive towards the Gandhian concept of Swaraj the village republics. It is through small efforts at local levels that our resources will be sustained for a better tomorrow.

The mission has begun. The future beckons our sense of responsibility and we must stand and work for it. What will happen if we do not take care of the earth? The Earth and the universe were created less than 10, years ago. This can be proven in 5 different ways. Not even a million years old! Rock can only bend without fracturing when it is softened by extreme heating which causes recrystallization or when the sediments have not yet fully hardened.

There are numerous locations around the world including the famous Grand Canyon where we observe massive sections of strata that have been tightly folded, without evidence of the sediments being heated. This is a major problem for evolutionists who believe these rock layers were laid down gradually over vast eons of time, forming the geologic record. However, it makes perfect sense to creationists who believe these layers were formed rapidly in the global, catastrophic Flood described in Genesis.

One discovery that has left evolutionists scrambling is a fossilized Tyrannosaurus rex femur with flexible connective tissue, branching blood vessels, and even intact cells! According to evolutionists, these dinosaur tissues are more than 65 million years old, but laboratory studies have shown that there is no known way—and likely none possible—for biological material to last more than thousands of years.

Could it be that evolutionists are completely wrong about how recently these dinosaurs lived? A biblical age of the earth about 6, years is consistent with the number of people alive today. In contrast, even a conservative evolutionary age of 50, years comes out to a staggering, impossibly high figure of 10 to the 99th power greater than the number of atoms in the universe.

So the idea of humans being alive for tens of thousands of years is absurd! Evidence 5 Astronomy: Recession of the Moon: The moon has an odd effect on earth. It affects the tide and pulls the waters in different directions. Because of this, the moon drifts farther and farther away from earth. Based on gravitational forces and the current rate of recession, we can calculate how much the moon has moved away over time.

In that amount of time, the earth would have only moved about feet. However, scientists believe that the moon is over 4 billion years old. This means, that about 1. Each of these topics breaks the idea of evolution. There are so many flaws with evolution and these topics only scratch the surface of the mistakes.

In conclusion, the earth is only 10, years max, due to geology, biology, anthropology and astronomy. The key factors to the Earth and universe. Sorry, copying is not allowed on our website.
