Earthquakes and volcanoes

What are the common locations for earthquakes and volcanoes?

Earthquakes and volcanoes often occur at high elevations on land (like the Rocky and Andes Mountains) and at low elevations underwater (like ocean trenches).

What is the relationship between volcano and earthquake patterns?

Linear patterns of volcanoes and earthquakes overlap on the Pacific coasts and ocean trenches

Where can clusters of earthquakes be found?

Non-linear clusters of earthquakes are found in the Himalayas

Where can clusters of volcanoes be found?

Non-linear clusters of volcanoes are found in the Western United States

What patterns can be observed at high elevations?

Volcanoes and earthquakes often occur together at high elevations on land and can also occur at high points on the ocean floor.

What patterns can be observed at low elevations?

Low elevations on continents have few or no volcanoes or earthquakes

How many tectonic plates cover the Earth's surface?

There are at least a dozen plates of different shapes and sizes covering the Earth's surface.

What is the coverage of Earth's tectonic plates?

Earth's entire surface is covered with plates

What can be found on top of the Earth's plates?

Typically both oceans and continents can share the same plate. There are few plates that only have continents or only the ocean on top of it.

Where are plate boundaries usually located?

Plate boundaries are usually found under oceans or along the edges of continents

Where do earthquakes commonly occur?

Earthquakes are more common than volcanoes and can occur on land or underwater

Where do volcanoes commonly occur?

Volcanoes can occur on land or underwater
