Earth's Structure and Processes: Interactive Learning Quizzes

Question 1

Which process is the primary cause of mountain formation?

Accepted Answer

Convergent plate boundaries, where one plate slides beneath another, melting and forming magma that rises to create mountains

Answer

Answer

Volcanic eruptions that accumulate layers of lava and ash

Question 2

Volcanic eruptions can pose serious risks to communities. Describe the various types of volcanic hazards and explain the steps that can be taken to reduce their impact.

Accepted Answer

A combination of scientific monitoring, land-use planning, early warning systems, and public education can significantly reduce the impact of volcanic hazards.

Answer

Volcanic hazards are limited to lava flows and ash clouds, which can be easily predicted and avoided.

Answer

Mitigation strategies for volcanic hazards involve only evacuating people from affected areas.
