Rock Cycle

The rock cycle encompasses various geological processes that transform rocks from one type to another. Weathering, driven by chemical reactions, rain, and wind, breaks down rocks into smaller particles.

Rock Cycle

Weathering Processes

Ice
Water
Chemical

acid is in the rain water so it reacts with some of the minerals in the rock around it speeding up its eroding progress

Mechanical

When rain displaces the soil

Wind
a light wind that carries large amounts dirt, sand and ash from one place to another

Tectonic Plate

Volcanoes
The inside of a volcano has a hot liquid substance which is called magma. When the magma has been cooled it turns into igneous rock
Earthquakes
Earthquakes are caused by shifts in tectonic plates

Metamorphic rock

Pressure
Heat

Sedimentary rock

is created by compaction and cementation of loose sediments that is tightly packed together

Igneous rock

is created by lava that has cooled
