Q

The Earth’s outer shell (lithosphere) is made up of
large slabs called tectonic plates that float on the semi-fluid layer of the
mantle below. These plates constantly move, but the edges where they interact
are often locked by friction. When the stress along these edges (or faults)
becomes too great, the plates suddenly shift, causing an earthquake.

Q

: In areas near volcanoes, earthquakes can be
triggered by the movement of magma (molten rock) beneath the
Earth’s surface. As magma rises, it fractures surrounding rocks,
creating seismic activity.

A

Volcanic Activity
