Breaking up is hard to do
The breaking down of rocks into smaller pieces.
What is weathering?
Chemical composition, particle size, texture, and luster are all examples of this.
What are properties of rocks?
The speed of water and size of particles determine how far rocks can travel, using your knowledge of stream tables, the this particle traveled the farthest.
What is clay?
This layer of the soil profile contains humus and needs organisms to help add nutrients to it.
What is topsoil?
What is "A" horizon?
This model showed how sediments are sorted by water.
What is a stream table?
The act of bumping and grinding of rocks that results in smaller particles.
What is abrasion?
These two tools are important for geologist to take into the field when doing research.
What are HCl and a hand lens?
Sediment that forms a delta at the mouth of a river landed there by this process.
What is deposition?
The areas where soil develops have these characteristics. (Name 2)
What are warm, wet, flat, and abundant with organisms?
Name two landforms that formed in the stream table after initially starting with a plateau.
What are canyon, river, delta, meander, basin, beach?
A lichen slowly breaks a rock down by this process.
What is chemical weathering?
A natural feature of the Earth's surface with a characteristic shape.
What is a landform?
The breaking down of a boulder into smaller particles is an example of this type of weathering.
What is physical weathering?
One cubic centimeter of this may take hundreds of years to form.
What is soil?
The outer curve of a meander experiences a faster flow of water which often leads to increased weathering and these processes.
What are erosion and deposition?
This happens when water fills cracks, freezes, expands, and repeats over and over.
What is ice wedging?
A river running through a canyon may expose more rock layers at higher elevations than lower elevations as a result of this.
What is the speed of Water?
What is the slope?
Name the process that transports (moves) large and small rock particles in a river.
What is erosion?
Minerals, organic materials, air, water, weathered rock particles, and humus are the main components of this.
What is soil?
In our class model, and as seen in the videos of stream tables, landforms were made by eroded sand. Name two.
What is a beach and a delta?
The two processes involved when large chunks of ice (glaciers) move over rocks.
What are weathering and erosion?
If you were able to visit a canyon in 1 million years you would most likely see this at the river level.
What is a new (older) rock layer?
This is the name of the rock sizing guide.
What is the Wentworth Scale?
Name two factors that contribute to the length of time it takes soil to form.
What are parent material, climate, topography, organic material, and time?
The stream table and Grand Canyon are similar because they both began with this landform.
What is a plateau?
