The Earth's surface that is covered by water is 3.6x10^10, compared to the amount if Earth's surface that is covered by land which is 1.8x10^8, approximately how many times greater is the amount of Earth's surface covered by water, compared to the surface cover by land? Write your answer in scientific notation.

Answer 1

To find the ratio between the surface covered by water and the surface covered by land, we divide the surface covered by water by the surface covered by land:

Ratio = (3.6x10^10) / (1.8x10^8)

To divide the numbers in scientific notation, we divide the coefficients (3.6 / 1.8) and subtract the exponents (10^10 / 10^8):

Ratio = 2 / 10^2 = 2x10^-2

Therefore, the amount of Earth's surface covered by water is approximately 2x10^-2 times greater than the surface covered by land.
