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.

During El Niño, what happens to the coastal marine ecosystems near Peru? They thrive. Their productivity increases. They collaps
agasfer [191]

Answer:

<u>1. Their productivity increases, 2. increased friction with the land surface, 3. They intensify, 4. It increases evaporation.</u>

Explanation:

  • When the El Nino a southern oscillation reaches the Peru coast it upwells warm water and which is beneficial to the fishes and marine life. As the upper water planktons depend on this nutrient-rich water and thus thrive and increase in productivity.
  • Its a fact that the cyclones drive their energy from the warm moisture supply of water from the oceans and seas and when they make a landfall they collapse and they can't move to the interior as the friction a force and the number of energy decreases and thus they fall.
  • When the tropical cyclones form in the warm waters they intensify and grow bigger in size and thus move further quickly.
  • As the sea sprays are salts that are ejected from the oceans they are a process of heat transfer and intensify the formation if a cyclone, transferring heat, momentum, and moisture into the air.

Is carbon neutral good for the environment and us humans
Paul [167]
Carbon neutral is a term used to describe carbon-based fuel that when burned will not increase carbon dioxide in the atmosphere. these fuels neither contribute to nor reduce the amount carbon so the carbon will remain the same.
so I think carbon neutral is good for the environment but not us humans
