The structure of the earth

Mantle

________: made from molten and semi molten rock.

Convection currents

________ causes two plates to collide.

Stage4

________: when magma cools it sinks towards the core where it is reheated.

Inner core

________: solid ball made from Nickle and iron.

Plate boundaries

________: where two plated meet and are separated by faults.

Oceanic plate

________: occurring under ocean.

convection currents

The plates are pulled apart by ________, molten magma comes to the surface through a crack called a fissure and creates new land.

crust

made from rock

Mantle

made from molten and semi molten rock

outer core

molten and made from Nickle and iron

inner core

solid ball made from Nickle and iron

oceanic plate

occurring under ocean

plate boundaries

where two plated meet and are separated by faults

stage 1

heat from the earths core causes magma to heat up and rise

stage 2

when hot magma reaches under the earths crust it moves in all directions dragging the crust with it

stage3

the hot magma cools as it is further from the core this makes it heavier

stage4

when magma cools it sinks towards the core where it is reheated

stage 5

this cycle is repeated again and again causing convection current
