Calculate the total mass of water in kg on Earth's surface from the following data: total planetary surface area: 510,066,000 km

irinina [24]

Answer:

The total mass of water in on Earth's surface is $3.61419\times 10^{22} kg$ .

Explanation:

Total planetary surface area = T = $510,066,000 km^2$

Total land area of planet = L = $148,647,000 km^2$

Total water area of planet = W

T = L + W

$510,066,000 km^2=148,647,000 km^2-W$

$W=510,066,000 km^2-148,647,000 km^2=361,419,000 km^2$

Volume = Area × Depth

Volume of water on earth = V

V= $361,419,000 km^2\times 100 km^=36,141,900,000 km^3$

$km^3=10^{12} L$

$V=36,141,900,000 km^3=36,141,900,000 \times 10^{12} L$

Total mass of total water on the earth = M

Density of the water,D = 1 g/mL = 0.001 kg/0.001 L=1 kg/L

1 g - 0.001 kg

1 mL = 0.001 L

$D=\frac{M}{V}$

$M=D\times V$

$M =1 kg/L\times 36,141,900,000 \times 10^{12} L=3.61419\times 10^{22} kg$

The total mass of water in on Earth's surface is $3.61419\times 10^{22} kg$ .

What is the relation of other subjects with geography ??

Sidana [21]

Geography uses other subject in it's studies. Very close to geography are geophysics and geology. Geophysics studies quantitatively physical phenomena of the planet Earth, geology studies composition of soil rocks and their development through history. Geography uses biology, statistics, mathematics and other subjects in order to better describe the Earth.
