To complete the rock cycle diagram, we need to fill in the blanks using the provided words:
metamorphic rock,
igneous rock,
sedimentary rock,
magma, and
sediment. Let's analyze the diagram step by step and determine the correct placement of each term.
Step-by-Step Analysis:
1.
Top Right (Melting inside the Earth):
- This process involves rocks being subjected to high temperatures deep within the Earth, causing them to melt into a molten state.
- The molten material is called
magma.
- Therefore, the blank here should be filled with
magma.
2.
Top Left (Cooling & Crystallizing):
- When magma cools and solidifies, it forms a type of rock known as
igneous rock.
- This cooling can occur either underground (intrusive igneous rock) or on the surface (extrusive igneous rock).
- Therefore, the blank here should be filled with
igneous rock.
3.
Middle Left (Weathering):
- Weathering breaks down rocks into smaller pieces through physical, chemical, or biological processes.
- The broken-down pieces are called
sediment.
- Therefore, the blank here should be filled with
sediment.
4.
Bottom (Cementing & Compaction):
- Sediment is transported by water, wind, or ice and eventually settles in layers.
- Over time, these sediment layers are compacted and cemented together to form
sedimentary rock.
- Therefore, the blank here should be filled with
sedimentary rock.
5.
Middle Right (Pressure & Heat):
- When sedimentary rock or other types of rock are subjected to high pressure and heat (but not enough to melt them completely), they undergo metamorphism and transform into
metamorphic rock.
- Therefore, the blank here should be filled with
metamorphic rock.
Final Filled Diagram:
- Top Right:
magma
- Top Left:
igneous rock
- Middle Left:
sediment
- Bottom:
sedimentary rock
- Middle Right:
metamorphic rock
Explanation:
The rock cycle illustrates how rocks can change from one type to another through various geological processes. Here’s a summary of the cycle based on the completed diagram:
1.
Magma forms when rocks melt inside the Earth.
2.
Igneous rock forms when magma cools and crystallizes.
3.
Sediment forms when igneous rock (or any rock) is weathered and broken down.
4.
Sedimentary rock forms when sediment is compacted and cemented.
5.
Metamorphic rock forms when sedimentary rock (or other rocks) is subjected to pressure and heat.
Final Answer:
\[
\boxed{\text{magma, igneous rock, sediment, sedimentary rock, metamorphic rock}}
\]
