Question

What is the percentage of the earth surface which is covered by water?
A. 65%
B. 80%
C. 70%
D. 97%

Answer 1

Hint:Apart from the ice-shaped water, there is the staggering volume of water that occurs beneath the surface of Earth.

Complete answer:
To answer this question, first we should know about Earth. Often, the Earth is contrasted to a majestic blue marble, particularly by those fortunate few who looked at it from orbit. This is due to the incidence of water on the surface of the planet. Water is not itself blue, but water provides blue light after reflection. Not that time afterward, our universe was thought to have been dry about 4.6 billion years ago, with high-energy collisions forming lava crust on the newborn Earth. According to this hypothesis, due to ice comets, trans-Neptunian bodies or protoplanets, water was carried to the world's oceans from the outer regions of the main asteroid belt that collided with Earth.
Now, let us find the solution from the given options-
- To split down the numbers, 96.5 percent of all Earth's water is constituted as salt water within the oceans, while the remainder 3.5 percent is freshwater lakes and frozen water trapped up in glaciers and the arctic ice cap.
-Nearly everything of that fresh water takes the form of ice which is to be exact, 69 percent of it.
- If you could dissolve all that ice, and the surface of the Earth would be smooth, the sea level would increase to 2.7 km. altitude
-Oceans occupy 70 percent of the Earth’s surface, accounting for just 0.02 percent of the gross mass of our world

Thus, the correct answer is option C 70%

Note: The amount of water such as groundwater, lakes and streams would amount just to more than 10.6 million km, which amounts to just more than 0.7%.
