Volcanic and Seismic Concepts

Front

What is a divergent boundary?

Back

A divergent boundary is a tectonic plate boundary where two plates move away from each other, often resulting in the formation of new crust, such as mid-ocean ridges.

Front

What type of lava do shield volcanoes erupt?

Back

Shield volcanoes erupt with thin, runny lava, which allows it to flow over great distances, creating gentle slopes.

Front

What is the role of a seismologist?

Back

A seismologist is a scientist who studies earthquakes and the movement of the Earth's crust.

Front

What evidence supports the theory of plate tectonics?

Back

Evidence includes fossils found on different continents, the locations of volcanoes and earthquakes, and the similarity in the coastlines of continents.

Front

What is the focus of an earthquake?

Back

The focus is the initial point within the Earth where an earthquake originates.

Front

What is a convergent boundary?

Back

A convergent boundary is a tectonic plate boundary where two plates move toward each other, often leading to one plate being forced beneath another.

Front

What is a transform boundary?

Back

A transform boundary is a tectonic plate boundary where two plates slide past one another horizontally.

Front

What are the characteristics of a composite volcano?

Back

Composite volcanoes are characterized by steep slopes and are formed from explosive eruptions of thick lava, ash, and cinders.

Front

What is the epicenter of an earthquake?

Back

The epicenter is the point on the Earth's surface directly above the focus of an earthquake.

Front

What is magma?

Back

Magma is molten rock located beneath the Earth's surface, which can erupt as lava during a volcanic eruption.
