How can you say that Earth is a unique planet?

Earth is unique because it is the only planet which exists life.It has air,water ,soil and all the other things which a human needs to survive.It is the third nearest planet from the sun so it is neither too hot nor too cold..

What makes the Earth a unique planet Class 9?

Answer: The earth is so for the only planet which consists of life- system. It is due to its ideal average temperature of 17°C to support the life and provide with atmosphere and hydrosphere to impart air and water essential for life.

What makes the Earth unique essay?

It has a solid and active surface with mountains, valleys, canyons, plains and so much more. Earth is special because it is an ocean planet. Water covers 70% of Earth’s surface. Earth’s atmosphere is made mostly of nitrogen and has plenty of oxygen for us to breathe.

Why is earth considered a unique planet Class 7?

The Earth is known as a unique planet as life exists on it. … The Earth has an atmosphere which is made up of gases like oxygen, nitrogen and carbon dioxide. While the Ozone layer prevents the harmful rays of the Sun from entering into the Earth, carbon dioxide traps the Sun’s heat, keeping the planet warm.

How is earth different from other planets?

It differs from the other planets because it has liquid water on its surface, maintains life, and has active plate movement. It rotates on its axis every 24 hours (a day) and revolves around the Sun every 365 days (a year). The Earth has one moon.

How unique Earth is together with its perfect position in the solar system?

The Earth is a very unique planet, compared to all planets that were discovered, this is because the position of the Earth is really ideal, because it isn’t too near or too far from the Sun, that is important for sustaining life.

Which among the given factors makes Earth unique in maintaining its temperature suitable for life?

The Earth has a suitable climate for the existence of all forms of life because of moderate amount of carbon dioxide, which is the driving factor for the survival of life forms. The temperature of planet Mercury ranges from 200°c below freezing to 375°c above.

How does the core help in sustaining life on our planet?

Not only is it likely the Earth’s largely iron core plays a role in the movements of continentsover millions of years, it plays a major role in preserving life here: The roiling iron heart of our planet helps maintain the Earth’s magnetic field, which helps shield life on the surface from damaging solar energy.

Is solar system unique or rare?

The Short Answer:

Our planetary system is the only one officially called “solar system,” but astronomers have discovered more than 3,200 other stars with planets orbiting them in our galaxy. Our solar system is just one specific planetary system—a star with planets orbiting around it.

What are 5 interesting facts about the moon?

  • The Moon’s surface is actually dark. …
  • The Sun and the Moon are not the same size. …
  • The Moon is drifting away from the Earth. …
  • The Moon was made when a rock smashed into Earth. …
  • The Moon makes the Earth move as well as the tides. …
  • The Moon has quakes too. …
  • There is water on the Moon!

What are five interesting facts about Earth?

“And yet, this tiny amount of water makes the difference between cool overcast summer days and warm clear days. And it is immensely important for climate. On average, clouds cool Earth by 13 degrees Fahrenheit relative to what global temperatures would be without clouds.”

How does the Earth release energy back into the atmosphere?

Earth returns an equal amount of energy back to space by reflecting some incoming light and by radiating heat (thermal infrared energy). Most solar energy is absorbed at the surface, while most heat is radiated back to space by the atmosphere.

What happens with the energy that enters the Earth’s atmosphere and to the surface?

About 23 percent of incoming solar energy is absorbed in the atmosphere by water vapor, dust, and ozone, and 48 percent passes through the atmosphere and is absorbed by the surface. Thus, about 71 percent of the total incoming solar energy is absorbed by the Earth system. … The remaining 48% is absorbed at the surface.

How does solar energy affect Earth’s atmosphere and surfaces?

The radiation warms the Earth’s surface, and the surface radiates some of the energy back out in the form of infrared waves. As they rise through the atmosphere, they are intercepted by greenhouse gases, such as water vapor and carbon dioxide. Greenhouse gases trap the heat that reflects back up into the atmosphere.

How are reflecting and scattering similar?

Scattering and reflection. Both phenomena occur and overlap. The main factor controlling them is particle size: scattering occurs for particles smaller than the wavelength of light, and reflection for bigger ones, but there is overlap. … Thus, more blue light than red light is transmitted backwards.

How does radiation scattering and reflection heat the earth?

The Earth absorbs most of the energy reaching its surface, a small fraction is reflected. In total approximately 70% of incoming radiation is absorbed by the atmosphere and the Earth’s surface while around 30% is reflected back to space and does not heat the surface.

How does the process of reflection scattering and absorption reduce the amount of the sun’s energy that reaches the earth’s surface?

Scattering of solar radiation within the atmosphere also accounts for a reduction of energy reaching Earth. Atmospheric gas molecules and aerosols deflect solar radiation from its original path, scattering (reflecting) some radiation back into deep space and some toward Earth’s surface.

Why is the moon orange?

Orange color due to thickness of Earth’s atmosphere near horizon. The orange color of a moon near the horizon is a true physical effect. It stems from the fact that – when you look toward the horizon – you’re looking through a greater thickness of Earth’s atmosphere than when you gaze up and overhead.

Why is the sun yellow?

The sun, itself, actually emits a wide range of frequencies of light. … Light that was trying to get to your eyes gets scattered away. So the remaining light has a lot less blue and slightly more red compared with white light, which is why the sun and sky directly around it appear yellowish during the day.

Why are clouds white?
