How does a convection cell in the mantle lead to volcanism at the mid-ocean ridge?

Geography

ivolga24 [154]3 years ago
5 0

The convection cell is basically a self-contained in which there is a motion, where the hotter fluid is moving upward because of the lesser density, while the cooler fluid is moving downward because it is denser. This leads to constant circular movement of the magma in the mantle layer, and the one that moves upward is constantly creating big pressure on the crust above it, penetrating through the cracks in it or melting it and intruding. As the magma pushes upward, it manages to get through the thinner and cracked crust between the plates that move away from each other at the divergent boundary. The magma reaches the ocean floor and quickly cools off, creating new crust, and that continues constantly, with more and more magma coming out and more and more new crust pilling up, eventually creating an underwater mountain range of volcanic origin known as mid-ocean ridge.

Which of these statements about saltwater is correct?
Mrac [35]
I think one of the statement here is erroneously written since A and B is the same statement. It should be that one choice is that "<span>Saltwater freezes at a lower temperature" and this is the correct answer. Saltwater experiences a freezing point depression due to the salt in the solution.</span>

Answer:

upper portion (6000ft - 6500 ft)

Explanation:

From the information given:

This activity involves exploring the Zion National Park geology. To achieve this, we need to download the Zion file & open it in Gougle Earth. This is followed by setting the vertical exaggeration to 0.5 & the measurement to feet/miles. The perspective view is also changed to a map view. Now, as viewed in Gougle Earth, the upper portion which is white in nature appears to be steeper than the lower portions. To the Toquerville, the area towards it is remarkably flat with slight undulations.
