What type of rock is formed by erosion and deposition?
What type of rock is formed by erosion and deposition?
Sedimentary rock
Which of these rocks are formed by volcanic activity select the two correct answers?
Granite and D. Basalt. Explanation: Granite is an intrusive plutonic rock, which is formed from solidified magma in large masses inside the earth’s crust.
Which type of rock is formed after all of these processes weathering erosion deposition compaction and cementation have occurred?
Formation of Sedimentary Rocks Sedimentary rocks are the product of 1) weathering of preexisting rocks, 2) transport of the weathering products, 3) deposition of the material, followed by 4) compaction, and 5) cementation of the sediment to form a rock. The latter two steps are called lithification.
Which of these rocks are formed by great pressure select the two correct answers?
The two correct answers are Marble and Schist. Metamorphic rocks are the rocks which are formed due to high pressure and temperature. They are found buried inside the earth where the temperature is very high. The temperature inside is very high and the so the buried also has very temperature and pressure.
Which of these rocks are formed by erosion and deposition select the two correct answers?
The correct answers are LIMESTONE AND SANDSTONE. These two rocks are examples of metamorphic rocks.
Is schist high or low grade?
The various types of foliated metamorphic rocks, listed in order of the grade or intensity of metamorphism and the type of foliation are slate, phyllite, schist, and gneiss (Figure 7.8)….7.2 Classification of Metamorphic Rocks.
| Basalt | |
| Very Low Grade | chlorite schist |
| Low Grade | chlorite schist |
| Medium Grade | amphibolite |
| High Grade | amphibolite |
What are the regional metamorphism?
Regional metamorphism is metamorphism that occurs over broad areas of the crust. Most regionally metamorphosed rocks occur in areas that have undergone deformation during an orogenic event resulting in mountain belts that have since been eroded to expose the metamorphic rocks.
What is the primary agent of regional metamorphism?
Temperature and pressure are the primary agents that drive metamorphism.
Where does dynamic metamorphism occur?
Dynamic metamorphism takes place anywhere that faulting occurs at depth in the crust. Thus, mylonites can be found at all plate boundaries, in rifts, and in collision zones.
