(diagram of sedimentary rock formation process and grand canyon rock layers chart with some handwritten answers)

Explanation:

Step1: Analyze the diagram's process

The diagram shows the formation of sedimentary rocks. The first process (rightmost with the rock breaking into pieces) is Weathering (breaks rocks into sediments).

Step2: Identify the next process

After weathering, the sediments are moved by a river/stream, which is Erosion (transport of sediments).

Step3: Next process in the cycle

Then, sediments are dropped (Deposition) where the river slows.

Step4: Final processes for rock formation

After deposition, Compaction and Cementation turn sediments into sedimentary rocks. So we label each box: the rightmost (rock breaking) is Weathering, the one with the river carrying sediments is Erosion, the one with sediments being dropped is Deposition, and the one with sediments turning to rock is Compaction and Cementation.

For the chart, using Grand Canyon rock layers:

• Kaibab: Limestone (biochemical, made of calcium carbonate from organisms)
• Hermit: Shale (mud/clay sediments)
• Coconino: Sandstone (sand sediments)
• Redwall: Limestone (similar to Kaibab, biochemical)
• Mauv: Limestone (biochemical)
• Supai Group: Various (e.g., sandstone, shale, limestone depending on layer)

Answer:

Diagram Labeling:

• Rightmost (rock fragmentation): Weathering
• River/stream carrying sediments: Erosion
• Sediments accumulating: Deposition
• Sediments to rock: Compaction and Cementation

Chart Completion (example for key layers):

Name of Rock	Type of Rock	Sediment It’s Made Of
Hermit	Shale	Mud, clay
Coconino	Sandstone	Sand (quartz grains)
Redwall	Limestone	Biochemical
Mauv	Limestone	Biochemical
Supai Group	Mixed (e.g., sandstone, shale)	Mixed sediments (sand, mud)
