How is the movement in the asthenosphere responsible for volcanoes and earthquakes?

Answer:

When plates move away from each other, the space between them gets filled with material, which rises to the surface, cools and forms mid-oceanic ridges. The Pacific Ocean is growing wider by about 18 cm per year as the plates diverge and the mid-oceanic ridge is built up. Where plates come into contact, energy is released. Plates sliding past each other cause friction and heat. Subducting plates melt into the mantle, and diverging plates create new crust material. Subducting plates, where one tectonic plate is being driven under another, are associated with volcanoes and earthquakes.  

When Alfred Wegener first proposed the idea of continental drift (the precursor idea to plate tectonic theory), it didn’t quite explain the full story. While he correctly showed that Africa and South America fitted together, his model wasn’t able to explain the violent forces that occur around the Earth’s crust. It wasn’t until the 1960s that a full explanation began to develop – the theory of plate tectonics.

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.

Which of the following can plate tectonics help explain? (Select all that apply.)
BaLLatris [955]

Answer:

- the distribution of earthquakes

- certain fossil distributions

- the distribution of volcanoes

- the location of mountain chains

Explanation:

The plate tectonics are crucial for the processes that happen on the surface or near it on our planet, as well as the physical features of it. The movement of the tectonic plates causes lot of stress when they interact, and from that stress, the crust deep inside cracks and adjusts, which releases a lot of energy and causes earthquakes. Also, on the plate boundaries, because the crust is cracking and is not as tough, the magma from the mantle manages to rise up, and as it reaches the surface it lifts up the land in a cone shape, creating volcanoes, be it as island or continental arcs. When continental tectonic plates collide, they don't subduct, but push against each other, and that enormous pressure lifts up the area around the boundary, gradually giving rise to mountain chains. The fossils are n interesting example as well, as they are one of the best clues about the movement of the tectonic plates. There are lot of fossils that are identical, from the same species, but found on different continents that are not connected in the present, indicating that in the past the continents had different positions and were connected.
