Question

activity (continued from previous page)

1. diagram: the image below summarizes the different stations in the rock cycle. draw an arrow to represent each possible transition from one rock type to another. then label each arrow with the process that occurs, such as \weathering\ or \erosion and deposition.\
2. practice: list the steps that would cause each transformation below.

a. intrusive igneous rock → sedimentary rock:

b. metamorphic rock → sediment:

c. sediment → sedimentary rock:

d. sedimentary rock → sediment:

Explanation:

Step1: Intrusive igneous rock to sedimentary rock

Weathering and erosion break down intrusive igneous rock into sediments. These sediments are then transported by agents like water, wind or ice. Finally, through compaction and cementation, the sediments form sedimentary rock.

Step2: Metamorphic rock to sediment

Weathering and erosion act on metamorphic rock, breaking it into smaller particles which become sediments.

Step3: Sediment to sedimentary rock

Sediments are deposited in layers. Over time, the weight of the over - lying layers causes compaction. Minerals in the water between the sediments precipitate and act as a cement, binding the sediments together to form sedimentary rock (cementation).

Step4: Sedimentary rock to sediment

Weathering and erosion break down sedimentary rock into sediments.

Answer:

A. Weathering and erosion, transportation, compaction and cementation
B. Weathering and erosion
C. Deposition, compaction, cementation
D. Weathering and erosion
