The Rock Cycle
| Question | Answer |
|---|---|
| A naturally occurring solid mixture of one or more minerals or organic matter is called | A rock |
| The continual process by which new rock forms form old rock is called | The rock cycle |
| Rocks have been used by humans throughout history for tools, weapons, and ________ | Buildings |
| The process in which water, wind, ice, and heat break down rock is called | Weathering |
| One reason that weathering is important is because it breaks down rock into fragments, or _______, from which sedimentary rocks are made. | Sediment |
| The process by which sediment is removed from its source is called | Erosion |
| During _______, sediment is deposited in bodies of water and other low-lying areas | Deposition |
| Sedimentary rock can be made when sediment is pressed and cemented together by______ dissolved in water. | Minerals |
| Earth's surface is called | Uplift |
| When uplifted rocks reach the Earth's _______, weathering, erosion, and deposition begin | Surface |
| Magma in the Earth's crust that has risen to the surface and cools and solidifies | Igneous rock |
| Rock that is forced downward and is altered due to heat and pressure | Metamorphic rock |
| Rocks that are partially or completely melted | Magma |
| Igneous rock at the Earth's surface that is weathered and wears away | Sediment |
| Sediment that washes down into rivers and oceans and is pressed and cemented together | Sedimentary rock |
| A rock at the Earth's surface is primarily affected by forces of | Weathering and erosion |
| A rock deep underground is primarily affected by forces of | Extreme heat and pressure |
| Scientists study rocks using what important criteria? | Composition and texture |
| What is the chemical makeup, or mineral content, of a rock based on? | Its composition |
| A rock that consists mostly of the mineral quartz will have a composition very similar to | Quartz |
| What do the size, shape, and positions of the grains that make up a rock determine? | The rock's texture |
| What factors can affect the texture of a sedimentary rock? | The size of the grains that make up the rock |
| What factors can affect the texture of an igneous rock? | The length of time the magma had to cool |
