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?
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 divide the area covered by water by the area covered by land.
Amount of Earth's surface covered by water: 3.6x10^10
Amount of Earth's surface covered by land: 1.8x10^8
Dividing the two values:
(3.6x10^10) / (1.8x10^8)
To divide exponential values, subtract the exponents:
(3.6 / 1.8) x (10^10 / 10^8)
Simplifying the division:
2 x 10^(10-8)
Now subtract the exponent:
2 x 10^2
This can be written as:
2 x 100 = 200
Therefore, the amount of Earth's surface covered by water is approximately 200 times greater than the surface covered by land.
