| Rocks can be made from manmade products like plastic. True or false? | False |
| If grains of an igneous rock are large, what would this indicate about the formation of the rock? | It cooled slowly and stayed hot for a long time |
| List in order from beginning to end the 4 steps involved in the formation of a sedimentary rock. | erosion,deposition, compaction, cementation |
| Compare and contrast Intrusive and extrusive rock. | Intrusive is formed under ground by magma and extrusive is formed above ground by lava. They both form from molten rock and are both Igneous rocks |
| The size of grains in an igneous rock are determined by... | rate of cooling |
| Coal is a sedimentary rock made up of organic matter that has become solid. Unlike limestone, coal is made up of: | plant remains |
| What type of rock is gneiss | metamorphic |
| You can group igneous rocks by the sizes of grains in them. Coarse grained rocks are___ and fine grained rocks are___. | intrusive;extrusive |
| Rocks that come from volcanos form the greater part of earth's crust. These rocks are: | Igneous rock |
| From deep within the earth molten magma pushes up, heating rocks that surround it. this process turns igneous and sedimentary rocks into: | metamorphic rocks |
| Chalk and limestone are made up of the remains of animals. They are: | sedimentary rocks |
| What kind of rock is basalt | Igneous rock |
| clay, silt, and sand are all: | sediments |
| Is quartz a rock if not, what is it? | It is not a rock, it is a mineral |
| The terms intrusive and extrusive are what type of rocks? | Igneous rocks |
| The terms clastic, organic and chemical refer to which type of rocks | Sedimentary rocks |
| The terms foliated and non-foliated refer to which type of rocks? | metamorphic rocks |
| Name the three major groups that rock are categorized into. | Igneous, sedimentary, and metamorphic |
| How are clastic rocks different from organic rocks? | Clastic rocks are made from particles of other rocks (sediment). Organic rocks are made from living organizms or the remains of them. |
| How are they similiar? | They are both sedimentary rocks |
| Are these rocks foliated or non-foliated? Slate, Gneiss, and Marble | Slate=foliated, Gneiss=foliated, and Marble=non-foliated |
