earth & atmosphere

the innermost layer of the earth which extends about halfway from the centre of the earth to the surface (it is split into outer and inner core)

the rocky outer layer of the earth (the thinnest layer)

the settling sediments that have moved away from their original rock

the breaking of a rock into sediments and their movement away from the original rock

formed when lava/magma cools and freezes (lava=extrusive magma=intrusive) their minerals are arranged in crystals e.g granite&basalt

molten rock below the earth’s surface

the layer of the earth below the crust which is solid but can flow very slowly - made of molten rock

formed when existing rocks are exposed to high heat and/or pressure over a long peridod of time (e.g marble)

chemicals that rocks are made from

porous materials have small gaps (that may contain substances) in their liquid or gas states - water can soak into a porous material

sequence of processes where rocks change from one type to another over millions of years

pieces of rock that have broken away from their original rock

formed from layers of sediment which may contain fossils (e.g chalk and limestone)

movement of sediments away from their original rock

the breaking down of rock into smaller pieces by physical, chemical, or biological processes

high heat and pressure

weathering, erosion, compaction, deposition

the cooling/solidification of magma/lava

extrusive

intrusive

smaller

larger

the mixture of gases surrounding the Earth
