Answer:
The total mass of water in on Earth's surface is 
.
Explanation:
Total planetary surface area = T = 
Total land area of planet = L = 
Total water area of planet = W
T = L + W
Volume = Area × Depth
Volume of water on earth = V
V= 
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
The total mass of water in on Earth's surface is .
Answer:
The good answers here are:
A. They are more reflective (higher albedo) than most of the terrestrial planets.
C. They are larger than the terrestrial planets.
Explanation:
Light colored clouds found there have a better, reflective albedo. And both planets are so much bigger than Earth, they´re the biggest planets of our solar system. These are some factors of their brightness in our sky.
