What kind of stress is created when the rock is being pushed?

When convergent plates collide, if both plates are pushed upward, what is formed?

Faults can occur at plate boundaries, near boundaries, and at other weakened areas of crust.

Ocean trenches always form at subduction zones where dense oceanic crust subducts.

What type of fault is created due to tension?

What are convection currents?

What instrument is typically used to measure seismic waves?

new molten material, that lies under the ocean, rises up creating new oceanic crust as it moves.

The mid-Atlantic ridge is formed at this boundary.

What stress occurs when rocks are pushed sideways?

Where do earthquakes usually occur?

Volcanoes are most often formed at this boundary.

Volcanoes occur at subduction zones

What is the lithosphere made of?

Volcanoes never form along subduction zones.

Continental crust is more dense than oceanic crust.

The circular pattern of heating, rising, cooling, sinking of magma in the mantle causing tectonic plates to move.
