Problem Analysis:
The image provided is a diagram of the
Rock Cycle, which illustrates the processes and transformations that rocks undergo over time. The task involves labeling the missing terms in the diagram and answering questions related to the rock cycle.
Step-by-Step Solution:
####
1. Labeling the Missing Terms in the Diagram:
The diagram shows different types of rocks and the processes they undergo. The missing terms are labeled as (1), (2), (3), and (4). We need to identify these based on the context of the rock cycle.
-
(1): This is a type of rock formed from sediments through compaction and cementation. Therefore, it is
sedimentary rock.
-
(2): These are the particles or fragments of rocks that result from weathering and erosion. Therefore, it is
sediments.
-
(3): This is a type of rock formed from magma cooling and solidifying. Therefore, it is
igneous rock.
-
(4): This is a type of rock formed under heat and/or pressure, changing the structure of existing rocks. Therefore, it is
metamorphic rock.
So, the labeled diagram will be:
- (1)
sedimentary rock
- (2)
sediments
- (3)
igneous rock
- (4)
metamorphic rock

2. Answering the Questions:
#####
6. What process must happen for igneous rock to turn into sediments?
Igneous rock must undergo
weathering and erosion to break down into smaller particles, which become sediments.
#####
7. How can sedimentary rocks turn into igneous rocks?
Sedimentary rocks can turn into igneous rocks through the process of
melting. When sedimentary rocks are subjected to high temperatures deep within the Earth, they melt into magma. Upon cooling and solidifying, the magma forms igneous rock.
#####
8. What are the three main types of rocks?
The three main types of rocks are:
-
Igneous rock
-
Sedimentary rock
-
Metamorphic rock
#####
9. How do sedimentary rocks turn into metamorphic rocks?
Sedimentary rocks can turn into metamorphic rocks through the process of
metamorphism. This occurs when sedimentary rocks are subjected to high heat and/or pressure, causing their mineral composition and texture to change without melting.
#####
10. How do sediments turn into sedimentary rocks?
Sediments turn into sedimentary rocks through the processes of
compaction and
cementation. Compaction squeezes the sediments together, reducing the spaces between them, while cementation involves minerals precipitating from water and binding the sediments together.
Final Answers:
1.
(1): Sedimentary rock
2.
(2): Sediments
3.
(3): Igneous rock
4.
(4): Metamorphic rock
6.
Weathering and erosion
7.
Melting
8.
Igneous rock, Sedimentary rock, Metamorphic rock
9.
Metamorphism
10.
Compaction and cementation
Boxed Final Answer:
\[
\boxed{
\text{(1): Sedimentary rock, (2): Sediments, (3): Igneous rock, (4): Metamorphic rock}
}
\]
