The Rock Cycle

Nese Selepeo

Weathering & Erosion

Occurs through the action of water & wind.

Transport & Deposition

Sediments created by weathering are transported & deposited by water & wind.


Sediments become a layer.

Compaction & Cementation

The sediments compress together & become stuck together.

Sedimentary Rocks

Type of rock formed by sediments compacting & cementing together.

All sedimentary rocks have mineral properties including, texture, composition, shape of sediments, size of sediments, sorting of sediments, & sediment structures.

Burial, High Temperatures & Pressures

Layers are close to the heat of the molten mantic & magma. This heat changes the rock from sedimentary or igneous rock to metamorphic rock.

Metamorphic Rocks

Type of rock formed from another type of rock being exposed to extreme heat & pressure changing it into another type of rock.

All metamorphic rocks have mineral properties including, luster, color, cleavage, specific gravity, & crystal form.


Hot magma & hot mantle melt the metamorphic rocks.

Magma from Molten Crust & Mantle

Hot mantle interacts with the lithosphere causing magma chambers to form.


Inside the lithosphere melts metamorphic & sedimentary rocks forming them into igneous rocks.

Intrusive Igneous Rock

Rock formed from cooling & solidification of magma beneath the Earth's surface cools slow, crystals will grow.

Intrusive Igneous Rocks are characterized by large crystal sizes. The cooling of magma in the Earth is much slower than near the surface, so large crystals are allowed to grow.

Extrusive Igneous Rock

Forms at or near the Earth;s surface.

Extrusive Igneous Rocks are characterized by fine-grained textures because they cool so fast that there's no time for large crystals to form.

Slow Uplift to the Surface

Rock layers are slowly lifted & exposed to Earth's surface. Can lead to rock layers undergo weathering & erosion.

External & Internal

The external parts of the rock cycle are weathering & erosion, transport & deposition, sedimentation,  compaction & cementation, & slow uplift to the surface.

The internal parts of the rock cycle are sedimentary rock, burial, high temperatures & pressures, metamorphic rock, melting, magma from molten crust & mantle, magma, intrusive igneous rock, & extrusive igneous rock.
