Final answer:
Scientists explore the mouth of an erupting volcano to collect samples, observe lava behavior, and measure temperature and pressure inside the volcano to gain insights into Earth's interior and understand the effects of volcanism on the environment.
Step-by-step explanation:
Volcanic Exploration
In order to study the Earth's interior, scientists may wear heat-resistant suits and explore the mouth of an erupting volcano. The purpose of this action is to collect samples of volcanic rocks and minerals, observe the behavior of lava inside the volcano, and measure the temperature and pressure inside the volcano.
By studying these factors, scientists can gain insights into the processes happening within the Earth and understand the effects of volcanism on the environment.
