Describe what happens during "compaction".
Sediments are squeezed together into layers by heat and pressure.
What causes the sun's apparent movement across the sky during the day?
The Earth's rotation on its axis
What is the third process in W.E.D.? Explain.
Deposition: The dropping off of sediments to a new location
Which statement best explains how the formation of deltas and sand dunes are similar?

A) Heat
B) Decaying marine life
C) Swamp
C) Swamp
Describe the process of "cementation".
Layers are naturally glued together and create a sedimentary rock.
Which statement is correct?
1. The sun orbits the Earth
2. The sun appears to rise in the east and set in the west

2. The sun appears to rise in the east and set in the west
What is the name of the process where ice weathers a rock into sediments?
Ice wedging
Describe how a canyon is formed including the W.E.D. processes and the agent of change.
A canyon is formed by weathering and erosion by water.
How are coal and natural gas/oil created differently?
Coal is formed on land while natural gas and oil are formed in the ocean.

Examples:
Shale
Conglomerate
Sandstone
Limestone
Coal
