The Earth’s surface that is covered by water is 3.6×1010
, compared to the amount of Earth’s surface that is covered by land which is 1.8×108
, approximately how many times greater is the amount of the Earth’s surface covered by water, compared to the surface covered by land? this is a division
To find the ratio of the Earth's surface covered by water to the surface covered by land, we can divide the area covered by water by the area covered by land:
Ratio = (Surface area covered by water) / (Surface area covered by land)
Ratio = (3.6 × 10^10) / (1.8 × 10^8)
Dividing these two numbers gives us:
Ratio ≈ 200
Therefore, the amount of the Earth's surface covered by water is approximately 200 times greater than the amount covered by land.
To calculate the approximate number of times greater the amount of the Earth's surface covered by water is compared to the surface covered by land, we can use division.
Step 1: Divide the surface covered by water by the surface covered by land.
3.6 × 10^10 / 1.8 × 10^8
Step 2: Simplify the division by dividing the numbers and subtracting the exponents.
(3.6 / 1.8) × (10^10 / 10^8)
Step 3: Simplify the fraction.
2 × 10^2
Step 4: Express the final answer.
The amount of Earth's surface covered by water is approximately 200 times greater than the surface covered by land.
To find the ratio of the Earth's surface covered by water to the surface covered by land, divide the area of water by the area of land.
Ratio = (Area covered by water) / (Area covered by land)
= (3.6 × 10^10) / (1.8 × 10^8)
To simplify this division, we can divide the coefficients and subtract the exponents since they have the same base (10).
Ratio = (3.6 / 1.8) × (10^10 / 10^8)
= 2 × (10^(10-8))
= 2 × 10^2
= 200
Therefore, the amount of the Earth's surface covered by water is approximately 200 times greater than the surface covered by land.
