Rock cycle stuff

igneous

rock formed from cooling magma or lava → crystallisation (crystal forming).
e.g basalt, diorite, granite

sedimentary rock

rock made by sediments being cemented together
e.g Chalk, Coal, Sandstone

metamorphic

rock that was once one form of rock but has changed to another under the influence of heat or pressure
e.g gneiss, quartzite, marble, schist, soapstone, and phyllite.

what does applying pressure to sediments do

form a sedimentary rock

what does weathering do to a sedimentary rock

turn it into sediment

what does heat+pressure do to sedimentary rock

turn into metamorphic rock

what does weathering do to a metamorphic rock

turn into sediment

what does melting do to a metamorphic rock

turn into magma

what does cooling do to magma

turns into igneous rock

what does melting do to a igneous rock

Rock

Any naturally occurring solid hard material made up of one or more minerals
Rocks are a collection of minerals

Extrusive (igneous)

e.g basalt, andesite, and rhyolite

rock formed from cooling magma or lava → crystallization (crystal formation)

Intrusive (igneous)

e.g Diorite, granite, and pegmatite

formed from magma that cools & solidifies in the crust (underground). Cools slowly ⇒ big crystals

Sediment

fine particles of solid material moved & deposited to a new location; can consist of rocks and minerals, as well as the remains of plants and animals.

Weathering & Erosion

break down materials

Transport

by wind & water

Deposition

sediments are put somewhere e.g. a lake or sea

Compaction

pressure squashes sediment

Cementation

particles bind together.
