Part 1: Convection occurs when warmer areas of a liquid or gas rise to cooler areas in the liquid or gas. Cooler liquid or gas then takes the place of the warmer areas which have risen higher. This results in a continuous circulation pattern.
Part 2: The Earth's crust is broken up into pieces called plates. The crust moves because of movements deep inside the earth. Heat rising and falling inside the mantle creates convection currents generated by radioactive decay in the core. The convection currents move the plates.
Um what do you mean by that ?

Explanation:
Neuroglia also known as glial cells which act as supporting cells for the nervous system and its functioning. These cells surrounds the neurons and produce insulation between them as they produce myelin sheath that coats the axon. There are six types of neuroglia cells and they all work to provide essential nutrients to the neuron cell and also maintain the homeostasis (under which it also regulate the interstitial fluid composition and repair tissue framework)
Hence option A is correct
