Q

What is the role of magma in endogenic processes?

A

Magma is the molten rock that can create new landforms through volcanic eruptions.

17

What are the three types of tectonic plate boundaries?

A

Divergent, Convergent, and Transform fault boundaries.

18
Q

True or False: Endogenic processes can contribute to the rock cycle.

A

True

19
Q

What is subsidence in the context of endogenic processes?

A

Subsidence is the sinking of the Earth’s surface due to geological processes.

20
Q

Multiple Choice: Which of the following phenomena is caused by endogenic processes? A) Landslides B) Tsunamis C) Earthquakes D) Floods

A

C) Earthquakes

21
Q

What is an example of a geological feature formed by endogenic processes?

Volcanoes.

22
Q

Fill in the blank: The theory of ________ explains the movement of the Earth’s lithosphere.

A

plate tectonics

23
Q

What is the significance of magma chambers in volcanic activity?

A

Magma chambers store magma beneath the surface, and their pressure can lead to volcanic eruptions.
