Question

Look carefully at this photograph and answer the following questions:

• What do you think caused this situation?
• What could that grey powder be?
• What does it tell us about the Earth’s internal forces?

Answer 1

• This situation appears to have been caused by a volcanic eruption, which covered the nearby area with ash and damaged houses, trees and other structures.
• The grey powder could be volcanic ash, made up of tiny particles of rock, minerals and volcanic material thrown into the air during an eruption.
• It shows that powerful forces exist inside the Earth. Heat and pressure inside the Earth can cause magma to rise and lead to volcanic eruptions. These internal forces can change the Earth’s surface and affect human life.
