The rock cycle

Is like a group of changes

A Path of a rock through the rock cycle.

Temperature- A measure of the average kinetic energy of individual atoms or molecules in the substance

Pressure- Forced being aliped to something

Lava- Magma that reaches the surface.

Magma- Is molten material that forms deep beneath earths surface.

MAGMA

Weathering Is the breaking down of rocks, soils, and minerals

having contact with the atmosphere.

Weathering

Sediments Is naturally occurring

material that is broken down by processes of weathering and erosion. Sediments are most often transported by water.

IMPORTANCE The rock cycle is important to me because

its forces has shaped earths surface for 4.5 billion years.

◦There are three types of rock

Rock #1

IGNEOUS ROCK

These are rocks that solidified directly from molten silicates, which geologists call magma

Intrusive- Is a geologic term used to describe igneous rock.

Extrusive- Formed from magma that has flowed out of cracks in the Earth’s surface.

Texture and Compaction Texture-The feel or appearance of a

surface.-The textures that the igneous rock has is glassy and crystal.

Compaction- The consolidation of sediments.

-The compaction the igneous rock has is that the solid of the crust rock is thickened.

Ultramafic- A rock of ultramatic composition

Importance- I think the igneous rock is important because their minerals and chemistry gives the geologist information.

Ultramafic and Importance

Rock #2

Sedimentary

Formed when igneous rocks are eroded as a sediment under the sea.

Erosion and Deposition Erosion- The gradual destruction or

reduction and weakening of something.

Deposition-

Compaction A compression of particles to make a dense

mass.

This has to do with the sedimentary rock because an sedimentary rock formed on the land and has a continual sedimentary environment.

Clastic and Chemical Clastic- An rock that is composed of

fragments of other rocks.

Chemical- A compound or substance that has been purified or prepare.

Importance I think Sedimentary rocks are important

because it contains the entire history of life on earth.

Rock #3

Metamorphic

Made up of igneous and sedimentary rocks of all ages which have subjected to intensePressure.

Metamorphism and stress Metamorphism- The composition or structure of a

rock.

Stress- Pressure or tension exerted on a material object.

The sedimentary rock has to do with metamorphism and that is, The limestone change into larger crystals.

Stress happens during metamorphism it can have a profound effect on the texture of the rock.

Foliated and non- Foliated Foliated- is a characteristic of some

metamorphosed rocks on which minerals are aligned in one direction so that the rock can readily be split in another direction.

Non-foliated-the appearance of certain metamorphic rocks.

Sedimentary rocks are non-foliated.

The carbon cycle Is a complex series of processes through

which all of the carbon atoms in existence rotate.

Importance I think the metamorphic is important

because the is one out of the three major important rocks. And its comprising the earth.
