This is the process by which rocks are broken down by breaking and banging.
What is physical weathering?
This is a map that uses contour lines to show the shape and elevation of the land.
What is a Topographic Map?
These are any remains, trace, or imprint of animal or plant life preserved in Earth's crust.
What are fossils?
This is bits of dead plant and animal parts in the soil.
What is humus?
This is the rubbing, grinding, and bumping of rocks that cause physical weathering.
What is abrasion?
What is chemical weathering?
These are the curved lines on a topographic map that represent a specific elevation.
What are contour lines?
Following the Law of Superposition, this is the oldest layer in the picture shown above.
What is Tapeats Sandstone?
This is a mix of humus, sand, silt, clay, gravel, and/or pebble.
What is soil?
This is the carrying away of weathered earth material by water, wind, or ice.
This is what could have caused this rock to crack.
Answers May Vary.
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?
Following the Law of Superposition, this is the most recent layer in the picture shown above.
What is Kaibab Formation?
This is a location where a lot of humus is found in soil.
Where is the forest?
This is the settling of sediments.
What is deposition?

This is the type of weathering that most likely caused the rock shapes you see above.
What is sand blown by wind?
This is the vertical distance or height above the sea level.
What is elevation?
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?
This is pieces of weathered rock such as sand, deposited by wind, water, ice
What is sediment?
Looking at the picture and the map key, the dashed symbol this earth material.
What is clay?
