Rock Cycle

Igneous

Facts:• Near volcanos• Formed by solidified molten rock • Cools when reaches surface

Examples:• Granite• Basalt

Metamorphic

Facts:• Formed when other rocks are changed by

heat, pressure, and chemical action.

Examples:• Marble• Gniess

Sedimentary

Facts:• Formed when combinations of rock fragments, seashells

, and chemicals are compressed in layers and hardened.

Examples: • Limestone• Sand stone

Magma

Rocks form in layers. It starts from the magma chamber then flows up. It goes in between all the layers and goes up into the earths surface. And forms rock. Some rocks form under ground, the layers compress together and make rock.

Physical properties of rocks

• Rocks can be identified by their physical properties.

• Different physical properties include:1. Luster2. Streak3. Hardness4. Color5. Texture• Each physical property can identify weather it

is sedimentary, igneous, or metamorphic

Rock Cycle Stages

1. Magma comes up from underground2. Cools down and turns into igneous 3. Heat and pressure turn igneous into

metamorphic 4. Breaks down and turns into sediment5. compacts and turns into sedimentary

Rock CycleMagma cools then turns into igneous, when its weathered it turns into sediment , compacting makes the sediment turn into sedimentary rock the heat and pressure turns it into metamorphic rock. Then that’s the rock cycle!!

How rocks are made

• Rocks are formed and made in many different ways and many different times.

• Rocks take at least millions to thousands of years to form.

• Different rocks form different ways• sedimentary: formed when combinations of rock

fragments are compressed together. • metamorphic: formed by heat and pressure.• igneous: formed when molten rock reaches the

earth surfaces and cools.

Extra Information

• The rock cycle never stops.• All rocks can be heated• When Earths tectonic plates move

around, they produce heat. When they come together, they make mountains and build rock.

• Rocks are made mostly of minerals or can be made of one mineral only.
