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. LAVA MAGMA

 Is the breaking down of rocks, soils, and minerals having contact with the atmosphere. Weathering

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

 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-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- The gradual destruction or reduction and weakening of something.  Deposition-

 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- An rock that is composed of fragments of other rocks.  Chemical- A compound or substance that has been purified or prepare.

 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 intense Pressure.

 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- 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.

 Is a complex series of processes through which all of the carbon atoms in existence rotate.

 I think the metamorphic is important because the is one out of the three major important rocks. And its comprising the earth.
