Volcanoes and Earthquakes

Front

What type of boundary is shown in the diagram?

Back

Divergent boundaries are where two tectonic plates move away from each other, often resulting in volcanic activity.

Front

What is the difference between magma and lava?

Back

Lava is magma that has reached the Earth's surface.

Front

Which of the following is not a classification of volcano?

Back

Magnate is not a classification of volcano; the main types are Shield, Composite, and Cinder Cone.

Front

Many earthquakes happen along the borders of...

Back

Tectonic Plates are the large sections of the Earth's crust that move and interact, causing earthquakes.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate goes beneath another, often leading to volcanic activity.

Front

What is a shield volcano?

Back

A shield volcano is a broad, domed volcano with gentle slopes, formed by the eruption of low-viscosity lava.

Front

What is a composite volcano?

Back

A composite volcano, or stratovolcano, is characterized by a combination of explosive eruptions and lava flows, resulting in steep slopes.

Front

What is a cinder cone volcano?

Back

A cinder cone volcano is the simplest type, built from particles and blobs of congealed lava ejected from a single vent.

Front

What causes an earthquake?

Back

An earthquake is caused by the sudden release of energy in the Earth's crust, creating seismic waves.

Front

What is the Richter scale?

Back

The Richter scale measures the magnitude of an earthquake, quantifying the energy released.
