Question

Select all of the answers that apply.

Which of the following help create volcanoes?

plate tectonics
built up magma
landslides
cracks in Earth's crust

Answer 1

The factors that help create volcanoes from the list provided are:

- **plate tectonics**: The movement of tectonic plates can lead to volcanic activity, especially at convergent and divergent boundaries.
- **built up magma**: Accumulation of magma beneath the Earth’s surface can lead to the formation of volcanoes when pressure builds and causes an eruption.
- **cracks in Earth's crust**: Cracks or fissures can allow magma to escape and lead to volcanic activity.

**Landslides** do not help create volcanoes; rather, they are a result of volcanic eruptions (when material collapses down the side of a volcano).

So, the applicable answers are:
- plate tectonics
- built up magma
- cracks in Earth's crust
