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:
People choose to settle along the coast because the interior of these countries is not suitable for life.
Explanation:
The countries in Northern Africa like Libya, Morocco, Algeria, and Tunisia, have almost all of their populations settled along or very near the coastlines. There are slight variations among the population patterns in these countries, but the general rule, except in Morocco, is that the interiors have little to no population and settlements.
The reason for this is very simple, lack of living conditions in the interior. While the coastline has multiple benefits for the people, like Mediterranean climate, patches of good soil, access to sea, easy movement of goods and people, the interior is the total opposite. The inteior is a hot desert, part of the Sahara Desert. There is little to no water, no soil, no sources of food, little to no natural resources, no infrastructre, and very dangerous sandstorms.
