Divergent boundary - plates move apart, creates mid-ocean ridges & rift valleys, can release molten material to form volcanic islands

Convergent boundary - plates come together, create mountains or volcanoes, oceanic crust always goes under continental crust

Transform boundary - plates slip past each other, fault ruptures and an earthquake occurs

Plate Tectonics - plates stay together to make up Earth's Crust

Tension - pulls or stretches on Earth’s crust

Compression - squeezes rock until it bends or breaks

Shearing - occurs when rock is being pushed in 2 opposite directions

Stretching - pulling on Earth's layers

A foot wall slips down to form a valley at a convergent plate boundary. Rock on either side of the valley becomes the mountains.

Walls of rock grind past each other in opposite directions. This pushes one side up above the other to form the mountains.

Compression causes rock to fold and bend, but not break, in the middle of a plate. The rock that folds upward becomes a series of mountains.

A hanging wall slips down at a divergent plate boundary. The slab of crust that falls forms a valley, and the slabs on each side form mountains.

Normal - footwall slides down the hanging wall, Reverse - hanging wall slides up over the footwall, Strike-slip - rock walls grind past each other in opposite directions.

Normal - hanging wall slides down the footwall, Reverse - footwall slides up over the hanging wall, Strike-slip - rock walls grind past each other in the same direction.

Normal - rock walls grind past each other in opposite directions, Reverse - footwall slides down the hanging wall, Strike-slip - hanging wall slides up over the footwall.

Normal - hanging wall slides up over the footwall, Reverse - rock walls grind past each other in opposite directions, Strike-slip - footwall slides down the hanging wall.

The size of the earthquake’s seismic waves

The energy released by the earthquake

The damage done by the earthquake

The length of the earthquake

displacing large volumes of water

increasing water temperature

changing water salinity

altering ocean currents

It would grow more intense

It would slow down, and the volcano might become dormant.

The lava would have more silica, leading to more violent eruptions

It would remain the same.

Yes, they do get stuck for a long period of time

Plates that collide wear down at their edges becoming rubble and sediment.

The plates that collide get compressed

Some plate edges subduct, or dive under other plate edges.

Active volcanoes erupt often, dormant volcanoes could erupt in the future, and extinct volcanoes are not expected to erupt again.

Active volcanoes never erupt, dormant volcanoes erupt often, and extinct volcanoes erupt occasionally.

Active volcanoes are always erupting, dormant volcanoes are extinct, and extinct volcanoes are dormant.

Magma is molten rock found underneath the Earth’s surface, while lava is molten rock found above Earth’s surface.

Magma is molten rock found above the Earth’s surface, while lava is molten rock found underneath Earth’s surface.

Magma and lava are both found above the Earth’s surface.

Magma and lava are both found underneath the Earth’s surface.
