For magma to transform into igneous rock, it must move to a cooler location. What is the main purpose of this environmental change?

To increase the pressure on the magma

To allow the magma to lose its heat

To add water, which is a key ingredient of rock

To expose it to oxygen, causing it to harden

What is the primary condition that causes magma to begin the process of forming igneous rock?

An increase in pressure from overlying rocks

A chemical reaction with gases in the atmosphere

The loss of thermal energy to a cooler surrounding environment

The absorption of water, which triggers hardening

Rapid solidification due to significant and quick heat loss to the water

A chemical change that transforms the lava into marine sediment

An increase in the lava's temperature from contact with saltwater

The immediate melting of surrounding oceanic crust
