Earthquakes and Volcanoes and Continental Drift--7th grade

Front

What is the fastest type of seismic wave?

Back

Primary Wave (P-Wave) travels faster than Secondary Waves and Surface Waves.

Front

What are the boundaries called where two tectonic plates move apart?

Back

Divergent Boundaries are where tectonic plates move apart, allowing magma to rise to the surface.

Front

What type of volcano has gradual slopes formed by slow cooling lava?

Back

Shield Volcano is characterized by its broad, gentle slopes and is formed by the eruption of low-viscosity lava.

Front

In which direction do seismic waves travel?

Back

Seismic waves travel in all directions from the point of origin.

Front

What are the large pieces of the Earth's surface called?

Back

Tectonic plates are the large, rigid pieces that make up the Earth's surface.

Front

What is a Secondary Wave?

Back

Secondary Wave (S-Wave) is a type of seismic wave that moves slower than Primary Waves and can only travel through solids.

Front

What is a Cinder Cone Volcano?

Back

A Cinder Cone Volcano is a steep, conical hill formed from the accumulation of volcanic debris.

Front

What is the process called when one tectonic plate is forced under another?

Back

Subduction is the process where one tectonic plate moves under another and sinks into the mantle.

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 the Earth's outer layer called?

Back

The Earth's outer layer is called the Crust.
