Why is the earth called the blue planet?

Why earth is called blue planet?
Blue planet earth.

Why earth is called blue planet As soon as white light strikes the earth’s surface, it is absorbed by the earth’s water reservoirs, which absorbs all other wavelengths of light except blue, with only blue light being reflected back to space from the earth.

The planet earth surface is covered by almost 70% of water and the rest 30 per cent constitute solid surfaces like continents, islands, mountains.

Hence when we see the earth from space it looks like a blue planet because the visible light radiation coming from the son contains VIBGYOR means violet, indigo, blue, green, orange and red, they together form white light.

But when white light falls on the earth surface its water reservoir absorbs the other wavelengths of light except blue and only blue light reflected back to space, that’s why we see the earth as the blue planet.

Why Earth is called blue planet

Why Earth is called a blue planet, to know it in detail we have to first know about the origin of the earth and its topological factors, so students let’s see why the earth is called the blue planet.

About 20 billion years ago an unimaginable natural phenomenon happened called “BIG BANG”.

The big bang theory

Big bang.

The big bang theory is given by American scientist GEORGE Lemaitre, according to him about 20 b.y.a a huge explosion happened in our vacant and empty space which have tremendous power and mass with huge temperature and light. which lead’s to the formation of the universe and galaxies, the Star system, planets, natural satellites, steroids gas clusters and other unknown things present in today’s time in our vast universe.

Scientists also say after the big bang our universe is expanding every second of time. till now it expends as much as we can’t even imagine its end and borderline, in one word it is beyond our imagination. Like we also don’t think where the ends of our thoughts.

So the most probable and pet question you ever ask, where we are in this vast dark deep space. so students don’t worry I’m here to eradicate your all confusion and misconceptions.

Milky way galaxy.

Milky way galaxy.

Thair are millions of galaxies in our universe but our home galaxy is a Milky Way galaxy that contains billions of Star systems, in a star system present called the solar system, here our home planet Earth is present.

Solar system.

The solar system constitutes 8 planets including Earth, more than 200 moons, steroids and gas clusters.

Our main location is earth it is 3rd distance and 5th largest planet from the sun in our solar system having a habitual environment and a sufficient amount of life-supporting gases and elements are present.

Earth’s atmosphere contains 78 per cent nitrogen and 21 Percent oxygen, and traces of other gases like carbon dioxide, argon etc.

Only Earth have oxygen insufficient amount for keeping life on earth, otherwise, no other planets in our solar system contain oxygen and life-supporting elements insufficient amount.

Among all metals, we knew till now iron constitutes about 34.6 Percent and this is the reason for which the earth has a very strong magnetic field.

Neptune.

For your kind information students, Neptune a planet of the solar system also looks like blue in colour but it doesn’t mean Neptune contains water, the whole planet Neptune is made up of ice having a hard environment for the survival of human beings.

Time scale.

– universe originated about 20 bya.

– solar system and Earth were formed about 4.5 bya.

– Life appeared around 4 billion years ago.

Summary of Why earth is called blue planet?

Learners will understand why the earth is referred to as the “blue planet” because the visible light radiation from the son contains VIBGYOR, which stands for violet-indigo-blue-green-orange-red and is combined to form white light when combined with other colours to form white light. When white light strikes the earth’s surface, it is absorbed by the earth’s water reservoir, which absorbs all other wavelengths of light except blue, with only blue light being reflected back to space. It is for this reason that we see the earth as a blue planet.

I’m here to clear up all of your misunderstandings and misinformation.

It is the earth that serves as our primary location, as it is the third and fifth largest planet in our solar system, and it has a habitable environment as well as an adequate supply of life-sustaining gases and elements.

The Earth’s atmosphere is composed primarily of nitrogen and oxygen, with traces of other gases such as carbon dioxide, argon, and other trace elements.
