Lesson 3+4 Rocks
| Question | Answer |
|---|---|
| Igneous Rock | A type of rock that forms from the cooling of molten rock at or below the Earth's surface. |
| Sedimentary Rock | A type of rock that forms when particles from other rocks or the remains of plants and animals are pressed and cemented together. |
| The Rock Cycle | The Earth's process of changing one type of rock into another type of rock. |
| What are the three major types of rocks? | Igneous, Sedimentary, and Metamorphic |
| What is the source of energy that drives the weathering and erosion of sedimentary rocks? | The source of energy is the sun and Earth's interior |
| High heat metals a deposit of sedimentary rock, which then hardens into a new rock. What kind of rock forms? | Igneous Rock forms from the cooling of melted rock (magma or lava) |
| You are examining a sample of igneous rock. What factors affect the kind of igneous rock found in the sample? | The temperature of the magma and its composition affect the kind of igneous rock that is formed. |
| What process can recycle sedimentary rock into sediment? | Weathering and erosion can take a sedimentary rock and turn it into sediment. |
| Describe a process that happens again and again in the rock cycle. | A process that happens over and over again in the rock cycle are melting weathering and erosion,heat and pressure and deposition. |
| Describe two different way that sedimentary rock can become igneous rock. | Melting into magma and lava or by heat and pressure turning into metamorphic and then melting into magma and lava. |
| Explain why the change from metamorphic rock to magma almost always occurs below Earth’s surface. | The change from metamorphic rock to magma always happens under ground because of the intense heat and pressure. |
