Put the following steps of the convection process in the correct order.

1. Gravity pulls cooler matter downward.

2. The matter expands and decreases in density.

3. An up-and-down flow of matter produces a convection current.

4. Matter is heated.

5. Warmed matter is forced upward.

Rylee Cobb · Answer 1

Answer: Option (A)

Explanation:

At the initial stage, the heat produced from the earth's core heats up the matter present in the lower mantle and due to this continuous heating the matter gets expand and looses its density, thereby forces the matter to move upward.

This warmer matters then rises up and temperature decreases, as a result of which the magma/matter becomes denser and again falls back under the action of gravity.

This continuous process is called the convection current.

Hence the correct option is (A)

I was going to say a) as well, but what was with all the low stars on the other answer? Is it wrong or were people just being salty?
