Explanation:
it serves as a source of living for man
Answer:
The movements involved in plate tectonics acted like a giant conveyor belt for earths lithosphere and the Mid ocean ridges occur where mantle material rises upward, creating new seafloor crust and pushing plates apart.
Explanation:
How does this action explain the differences between seafloor crust and continental crust?
The movements involved in plate tectonics acted like a giant conveyor belt for earths lithosphere and the Mid ocean ridges occur where mantle material rises upward, creating new seafloor crust and pushing plates apart.
Main differences between sea floor crust and continental crusti is that oceanic crust and continental crust are less dense than the mantle, but sea floor crust is denser than continental crust. It also noticed that subduction occurs at ocean trenches, where dense seafloor crust pushes under less dense continental crust, thereby returning seafloor crust to the mantle. The subducting seafloor crust may partially melt, with lower density material melting first and erupting from volcanoes as new continental crust.
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:
y=x-8
Explanation:
Same slope; different y-intercept.
