1. What is the Rock Cycle The rock cycle is the interactions among earths water, air. And land that continuously causes the rocks to change to make up the rock cycle

2. The Rock Cycle 1. The rock cycle starts when rock at earth's surface are broken down into smaller pieces called sediments. 2. When sediments are compacted and cemented, sedimentary rocks form or it can become sediment thats when it alternate paths in the cycle that means they can go in different patterns. 3. Any type of rock that is changed by heat, pressure, or fluids becomes a metamorphic rock or it can become sediment. 4. When rocks melt deep beneath Earth's surface it becomes magma. 5. When magma or lava cools and solidifies, igneous rocks form and then it could go back a restart or it could go to metamorphic rock.

3. Important to the Rock Cycle Temperature plays a big importance in the rock cycle because when sedimentary rocks are heated they become metamorphic rock and when the metamorphic rock is heated it becomes magma and when magma cools own it becomes igneous. Pressure is also a big part because when sedimentary rocks are compacted or pressured it becomes metamorphic. Weathering is when rocks are broken down by water, air, and living things to produce sediment and the cycle starts over again. The rock cycle is important because a lot of things we used were made by rock and without the rock cycle we wouldn't have foundational, strong rocks.

4. Igneous Rocks The word igneous comes from the Latin word “ignis” which means fire. Intrusive igneous rocks is rocks that form when magma hardens beneath Earth’s surface Extrusive igneous rocks is when lava hardness Texture is a big part of classifying a igneous rock, some of the textures are Coarse- Grained, Fine- Grained,Glassy, and Porphyritic. Coarse- Grained is the slow cooling results in the formation of large crystals. Fine- Grained is the rapid cooling of magma or lava results in rocks with small, interconnected mineral grains. Glassy is when lava spews onto the Earth’s surface. Porphyritic is when a large body of magma located deep within Earth may take tens of thousands of years to harden Composition is also a very important part in classifying Igneous rocks some of the composition are Granitic, Basaltic, and other groups Granitic is the slight light colored silicate mineral quartz one of the rocks are Rhyolite Basaltic is the dark silicate minerals, the most common Basaltic rock is the Gabbro. The other groups are in between Granitic and Basaltic which not light but not dark, one of these rocks are Peridotite, its chemical composition is Ultramafic. Ultramafic makes up much of the the Earth’s upper mantle with peridotite.

5. 5 Sedimentary Rocks The word Sedimentary comes from the latin word Sedimentum which means Settling. Erosion involves weathering and the removal of rock. When an agent of erosion-water,wind,ice, or gravity- loses energy, it drops the sediments. This process is called deposition Compaction is a process that squeezes, or compacts, sediments Clastic Sedimentary rocks is a classification. They are made with weathered bits of rocks and minerals. An example of these rocks is shale. Chemical Sedimentary rocks is also a classification. When dissolved minerals precipitate, or separate from water solutions. An example of this rock is sandstone. The Sedimentary rocks are very important because its the only rock that uses erosion 5

6. 6 Metamorphic Rock The Metamorphic is a type of rock that is changed by heat, pressure, or fluids. Metamorphism is very appropriate name for this process because it means to change form. Stress,which is also known as pressure, increases with depth just like temperature. Foliated metamorphic rock is a texture that gives the rock a layered appearance. One of these rocks are called Gneiss A non foliated metamorphic rock is a rock that does not exhibit a banded or layer appearance. One of these rocks are marble 6

7. 7 The Carbon Cycle The carbon cycle is when carbon moved among Earth’s major spheres by the way of the carbon cycle. These are the steps. 1. The carbon is the atmosphere is taken out. 2. The carbon enters plants into the animal in the Earth 3. Carbon from atmosphere into the bodies of water 4. Carbon goes from living things to land 5. Then carbon goes back into the atmosphere 7
