what cause earthquakes

Question

what cause earthquakes

Blocks of crust slide against one another, often at plate boundaries.

Pressure builds up in the molten rock beneath Earth's crust and causes it to shake.

Tectonic plates break apart into smaller plates, and the crumbling causes shaking.

Sudden motions in Earth's mantle cause the crust to shift.

Answer 2

The correct answer is: Blocks of crust slide against one another, often at plate boundaries.

Answer 3

There isn't a single answer to the question "What causes earthquakes?" as earthquakes can occur due to multiple factors. However, if you would like to select only one option, a common cause of earthquakes is when blocks of crust slide against one another, often at plate boundaries. These blocks of crust are part of the Earth's outer layer, called the lithosphere, which is divided into several large and small tectonic plates. These plates are constantly in motion, albeit very slow and imperceptible to us. At plate boundaries, the plates interact with each other in different ways. One common boundary is called a transform boundary, where two plates slide past each other horizontally. This movement can generate stress and pressure between the blocks of crust. Eventually, when the stress overcomes the friction holding the crustal blocks together, it results in an earthquake, causing the ground to shake. So, the sliding of crustal plates at plate boundaries is one of the primary causes of earthquakes.
