What are rocks?

Back to Menu organic inorganic matter Rocks are a combination of minerals and other materials (organic / inorganic matter)

Texture What is rock Texture?

Texture Texture is the size, shape, or pattern of the grains that make up a rock. Back to Menu

Texture How would you describe the Texture of each rock shown below?

Back to Menu difficult to see easy to see Fine grained (difficult to see) and Coarse grained (easy to see)

Describe this picture and what it represents?

Rock Cycle This picture illustrates the Rock Cycle: the recurring process of rock creation and destruction. Back to Menu

What are the 3 types of rocks? Briefly describe how each type is formed.

Igneous Igneous are formed from cooling of molten material. Sedimentary Sedimentary are formed from compaction of sediments. Metamorphic Metamorphic are formed from heat and pressure. Back to Menu Final Jeopardy

LavaMagma What is the difference between Lava and Magma?

Lava Lava is molten material that reaches the surface. Magma Magma is molten material below the surface. Back to Menu

What are the 3 ways Igneous rocks are classified?

OriginTexture Mineral Composition Back to Menu

Igneous rocks are described by where they form. What are the two ways?

Intrusive rocks form inside Earth. Extrusive rocks form on Earth’s surface. Back to Menu

Texture What are the types of Texture an Igneous rock can have?

Coarse Grain: can be seen with the unaided eye Fine Grain: small and difficult to see Porphyritic: both coarse & fine grains No grains: cooled too quickly Back to Menu

What can you determine about the chemical composition of these two igneous rocks?

Back to Menu Final Jeopardy felsic One has a high silica content (felsic), and the other has a very low silica content (mafic).

Are Metamorphic rocks likely to contain fossils? Explain.

Back to Menu No. Metamorphic rocks go through extreme heat and pressure, which would destroy any fossils present. Sedimentary rocks are the only type that will contain fossils.

Metamorphic rocks can be classified in two ways. Describe what they are.

Foliatedgrains arranged in layersNon-Foliatedgrains arranged randomly Metamorphic rocks can be either Foliated (grains arranged in layers) or Non-Foliated (grains arranged randomly). Back to Menu Final Jeopardy

Sediments What are Sediments?

Sediments Sediments are pieces of rock, mineral, or organic matter. Back to Menu

Weathering Erosion Explain Weathering and Erosion.

Weathering Erosion Weathering is the breaking down of material into sediment. Erosion is the carrying away of sediment by wind or water. Back to Menu

List the steps of Sedimentary rock formation in the correct order.

Weathering Erosion Deposition Compaction Cementation Weathering  Erosion  Deposition  Compaction  Cementation Back to Menu

What are the 3 types of Sedimentary rocks?

Clastic Clastic are rock fragments squeezed together. Organic Organic contain remains of plants and animals. Chemical Chemical form when dissolved minerals crystallize Back to Menu

What are the major types of weathering? Give 3 examples of each type.

Mechanical Weathering Mechanical Weathering includes Abrasion, freeze/thaw, plants, and animal activity. Chemical Weathering Chemical Weathering includes Acid rain, water, oxygen, & carbon dioxide. Back to Menu Final Jeopardy
