The Earth’s surface that is covered by water is 3.6×10^10 , compared to the amount of Earth’s surface that is covered by land which is 1.8×10^8 , approximately how many times greater is the amount of the Earth’s surface covered by water, compared to the surface covered by land?
To find out how many times greater the amount of Earth's surface covered by water is compared to the surface covered by land, we need to divide the surface area covered by water by the surface area covered by land.
Surface area covered by water = 3.6×10^10
Surface area covered by land = 1.8×10^8
The division would look like this:
(3.6×10^10)/(1.8×10^8)
This can be simplified by dividing the coefficient (3.6/1.8) and subtracting the exponents (10^10 - 10^8):
= 2 * 10^(10-8)
= 2 * 10^2
= 2 * 100
= 200
Therefore, the surface area covered by water is approximately 200 times greater than the surface area covered by land.
