Answer 1

Holes in volcanic rocks illustrates a low pressure and rapid cooling environment(surface of the earth).

Explanation:

Holes in rocks are usually found in a special type of volcanic rock called pumice. The holes signifies a melt that has a lot of dissolved gases in them and they solidify rapid under surface temperature.

• Pockets of holes found in some rocks are as a result of trapped gases in cavities of a solidifying magma.
• The magma must erupt explosively so that the gases will not have enough time to escape.
• During an extrusive magma activity, the low pressure allows for dissolved gases to collects in cavities and magma cools rapidly around them due to the low surface temperature.
• The cavities left behind when the gases escape is the hole formed in volcanic rocks.
