Drop target process that changes sedimentary rock to metamorphic rock
Drop target process that changes sediment to sedimentary rock
Drop target process than changes igneous rock to sediment
- Metamorphism
- Cementation and compaction
- Weathering and erosion
To answer this question step-by-step, here are the processes that correspond to each drop target:
1. Process that changes sedimentary rock to metamorphic rock:
Metamorphism is the process that changes sedimentary rock to metamorphic rock. During metamorphism, existing rocks undergo intense heat, pressure, or both, causing them to undergo physical and chemical changes. These changes result in the formation of new minerals and textures, transforming the sedimentary rock into metamorphic rock.
2. Process that changes sediment to sedimentary rock:
The process that changes loose sediment into sedimentary rock is called sedimentation. Sedimentation occurs when sediments, which are loose particles of rocks, minerals, and organic materials, accumulate and are compacted over time. These sediments can be derived from various sources, such as weathering and erosion of existing rocks or the remains of plants and animals. Through the process of lithification, the sediments are cemented together by pressure and chemical reactions, forming sedimentary rock.
3. Process that changes igneous rock to sediment:
The process that changes igneous rock to sediment is called weathering and erosion. Weathering refers to the physical and chemical breakdown of rocks into smaller fragments or particles. This can occur through processes like freeze-thaw cycles, abrasion, chemical reactions, or biological activity. Once the igneous rock has been weathered, it can be transported and deposited by agents like wind, water, or ice during erosion. The resulting sediment can then accumulate and undergo further processes to become sedimentary rock.
Remember, the rock cycle is a continuous process, where rocks can undergo different transformations depending on the physical and chemical conditions they are exposed to over time.
To identify the processes in the rock cycle that are represented by the given diagram, we need to understand the different types of rocks and the processes involved in their formation. Here is how you can determine the correct answers:
1. Changing sedimentary rock to metamorphic rock:
Metamorphic rocks are formed through the process of metamorphism, which involves the transformation of pre-existing rocks under high pressure, heat, or both. To locate the appropriate process on the diagram, look for an arrow or line that depicts the formation of metamorphic rock from sedimentary rock. Once you find it, drop the given target statement on that process.
2. Changing sediment to sedimentary rock:
Sedimentary rocks are formed when loose sediment, such as sand, gravel, or mud, is compacted and then cemented together over time. Look for an arrow or line on the diagram that represents the transformation of sediment into sedimentary rock. Place the second target statement on that process.
3. Changing igneous rock to sediment:
Igneous rocks are formed from the cooling and solidification of molten magma or lava. To determine the process shown on the diagram, locate the transformation from igneous rock to sediment. This process involves the weathering and erosion of the igneous rock, breaking it down into smaller particles that eventually become sediment. Place the given target statement on this process.
By following these steps and carefully analyzing the diagram, you will be able to identify the correct processes for each target statement in the context of the rock cycle.
