The crust is the part you walk on, and it's the surface of the earth.

Where do new sections of crust come from during seafloor spreading?

VashaNatasha [74]

Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor. Eventually, the crust cracks.

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 $3.61419\times 10^{22} kg$ .

Answer: Many factors (Cold climate drivers) Can influence earths climate such as changes in the suns intensity and volcanic eruption’s, as well as heat trapping gases in the atmosphere. The scientific evidence suggests that it is highly likely that humans are causing global warming

hope this helps you / have a nice day

If tectonic plates collide it forms convergent plate boundaries. if tectonic plates separate they form divergent plate boundaries
