Crust, mantle, core

Continental crust is thinner and denser than oceanic crust

Continental crust is thicker and less dense than oceanic crust

Both types of crust have the same thickness and density

Oceanic crust is older and made of granite

The crust plus the rigid uppermost mantle, broken into plates

Only the crust

The hot, partly molten layer that flows slowly

The liquid outer core

It is completely solid and rigid

It is hot and partly molten, so it can flow slowly like a thick fluid

It is frozen solid

It is made of light granite

Energy from the Sun heating the surface

Energy from ocean tides

Heat from the Earth's formation and from radioactive decay

Friction between continents

They blow the plates like wind

Hot mantle rises, cools and sinks in loops, dragging the plates resting on the asthenosphere

They pull the plates with magnetism

They have no effect on the plates

The colour of the oceans

The height of clouds

The phases of the Moon

The jigsaw fit of continents and matching fossils across oceans

They move apart and magma rises to form new crust

They move toward each other and one subducts

They slide past each other along a fault

They stay completely still

A deep ocean trench

A mid-ocean ridge such as the Mid-Atlantic Ridge

Fold mountains formed by collision

A transform fault with no volcanoes

Because the oceanic crust is less dense

Because the oceanic crust is denser and therefore sinks beneath the lighter continental crust

Because the continental crust is thinner

Because the plates are moving apart

Mid-ocean ridges and gentle volcanoes only

Earthquakes only, with no volcanoes

Deep ocean trenches, fold mountains, explosive volcanoes and earthquakes

No landforms or hazards at all

A mid-ocean ridge

A rift valley

A deep ocean trench with subduction

Fold mountains such as the Himalayas

Neither created nor destroyed, the plates slide past each other

New crust is created

Crust is destroyed by subduction

Crust melts to form magma

Because magma rises easily there

Because friction as plates jerk past each other releases earthquakes, but no magma rises since no crust is made or destroyed

Because the plates move very fast and smoothly

Because the crust is too thin for earthquakes

The Mid-Atlantic Ridge

The Himalayan collision zone

The San Andreas Fault

The East African Rift
