To determine how many times greater the amount of Earth's surface covered by water is compared to the surface covered by land, we can perform a division using the values you provided.
Let's define:
- The surface area covered by water: \( 3.6 \times 10^{10} \)
- The surface area covered by land: \( 1.8 \times 10^{8} \)
We can compute the ratio as follows:
\[ \text{Ratio} = \frac{\text{Surface area covered by water}}{\text{Surface area covered by land}} = \frac{3.6 \times 10^{10}}{1.8 \times 10^{8}} \]
Now, we can simplify the expression:
\[ \text{Ratio} = \frac{3.6}{1.8} \times \frac{10^{10}}{10^{8}} = 2 \times 10^{(10-8)} = 2 \times 10^{2} = 2 \times 100 = 200 \]
Thus, the amount of Earth's surface covered by water is approximately 200 times greater than the surface covered by land.
