Front

What type of volcano is broad and gently sloped, with eruptions consisting of hot, flowing basaltic lava?

Back

Shield volcano

Front

What type of volcano is tall with steep sides, built up from layers of viscous lava, ash, and volcanic bombs?

Back

Composite volcano

Front

Which type of seismic wave travels through the layers of the Earth and is known as an S wave?

Back

Secondary wave (S wave)

Front

What happens to heat in convection currents?

Back

Heat rises when convection currents are moving.

Front

In which layer of the Earth are convection currents found?

Back

Mantle

Front

What is the primary composition of shield volcanoes?

Back

Basaltic lava

Front

What are the characteristics of composite volcanoes?

Back

They have steep sides and are built from layers of lava, ash, and volcanic rocks.

Front

What is the difference between S waves and P waves?

Back

S waves are shear waves that cannot travel through liquids, while P waves are compressional waves that can travel through solids and liquids.

Front

What is the role of convection currents in the Earth's mantle?

Back

They help drive plate tectonics and the movement of the Earth's crust.

Front

What type of volcano is formed from explosive eruptions and has a conical shape?

Back

Cinder cone volcano
