Question

Which step is not part of a normal convection cycle?

Answer 1

Answer:

B. Warmed air rises away from the surface.

Explanation:

It can be said that the convection cycle responsible for the dynamics of the lithospheric plates occurs not only in the nucleus, but also in the mantle and is transferred as a result transfers determined on the Earth's surface.

In this sense, we know that when the presence of a hot fluid occurs, the substances swell, which results in a reduction in density and then, this increases, since it is less dense than the medium where it is inserted. Thus, convection currents result from the heat flow that causes the hotter material, therefore less dense, to be propelled to the surface.

In summary, we can say that the normal convection cycle occurs when a hot fluid expands, it reduces density and rises because it is less dense than the surrounding environment. Convection currents are the result of the heat flow that makes the hotter material less dense and ascends the surface. This phenomenon occurs in the nucleus and in the mantle, and as a result it transfers certain heat from the interior to the Earth's surface.

Answer 2

Answer:

Air flows from a high-pressure area to a low-pressure area.
