Erosion/Deposition
100

This is the process by which rocks are broken down by breaking and banging.

What is physical weathering?

100

This is a map that uses contour lines to show the shape and elevation of the land.

What is a Topographic Map?

100

These are any remains, trace, or imprint of animal or plant life preserved in Earth's crust.

What are fossils?

100

This is bits of dead plant and animal parts in the soil.

What is humus?

100

This is the rubbing, grinding, and bumping of rocks that cause physical weathering.

What is abrasion?

200
This is the process by which minerals in a rock can change due to chemicals in water and air.

What is chemical weathering?

200

These are the curved lines on a topographic map that represent a specific elevation.

What are contour lines?

200

Following the Law of Superposition, this is the oldest layer in the picture shown above.

What is Tapeats Sandstone?

200

This is a mix of humus, sand, silt, clay, gravel, and/or pebble.

What is soil?

200

This is the carrying away of weathered earth material by water, wind, or ice.

What is erosion​?​​​
300

This is what could have caused this rock to crack.

Answers May Vary.

300

Between Line A and Line B is 20 meters. This is the change in elevation between contour line A and contour line C.

What is 40 meters?

300

Following the Law of Superposition, this is the most recent layer in the picture shown above.

What is Kaibab Formation?

300

This is a location where a lot of humus is found in soil.

Where is the forest?

300

This is the settling of sediments.

What is deposition?

400

This is the type of weathering that most likely caused the rock shapes you see above.

What is sand blown by wind?

400

This is the vertical distance or height above the sea level.

What is elevation?

400

This is the principle that rock layers and the fossils they contain are arranged in layers and that lower sedimentary layers are older than higher layers of rock.

What is superposition?

400

This is pieces of weathered rock such as sand, deposited by wind, water, ice

What is sediment?

400

Looking at the picture and the map key, the dashed symbol this earth material.

What is clay?
