The answer is; geysers
Due to the water underground being heated from geological reason such as heat from magma chambers, the water heats up and expands. The pressure of the rock above the water causes it to reach very high pressures. The water finds cracks and fissures in the rocks above until it reached the surface. The pressure releases and the water eject from the ground into a hot fountain.
They are similar to those of primary succession, primary succession occurs in an area without any initial. Succession always begins on a barren surface, whereas secondary succession be gains in environments that already possess soil. I hope this helps.
The answer to question 1 is A.
