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:
b) the Pacific plate has carried the volcanoes away from the hot spot that formed them
Explanation:
The Hawaiian islands all have volcanic origin. Some are not active, while some still are. All of these islands have been active volcanoes at one point of time, and they have been created by a hot spot that lies beneath the Pacific plate. The hot spot has such a power that it actually manages to break through the central part of the plate where its crust is the strongest and densest. As the magma manages to come out above the water, it manages to create volcanic islands. The Pacific plate though is moving, it is not static, so it drags the volcanic islands away from the hot spot, causing their extinguishing. As those islands are moved away, the hot spot creates new volcanic islands, and the process constantly continuous, resulting in a volcanic island chain.
small even though Alaska is a big state it is covered in snow most of the time, and know one will want to live there for their whole life.
