Ground composition
The name of the sphere containing all rock and ground material
Geosphere
What are the two types of weathering?
Mechanical and Chemical
In every coastal region, ocean deposition creates
Beaches
Headland
Rock breaks into smaller pieces
Mechanical
A= top soil/Humus B= Subsoil, C= Bed rock
Define Erosion
Sediment carried away by an outside force
Deposition at the end of a river will form what?
A Delta
What are the two actions a glacier can perform to change a land
Abrasion and Plucking
An underground cave forms
Chemical
Landslide or Mudslide
Earthworms are considered _____ because they break down organisms in the soil producing Humus
Decomposers
Sand Dunes
When sea arches fall due to wave action they form
Sea stacks
Pressure changes on the surface causes a sinkhole
Mechanical
What are the two materials you will find in Humus
Decaying organisms and Dead plants
What kind of rock is easily broken down through chemical weathering?
Limestone
Formed by the pull of gravity on sediment in a mountain valley
Alluvial Fan
What are the three landforms that can be created through wave deposition
Sandbars, Spits, Barrier Island
Chemical
The main factor that can determine the rate of weathering in a rock
The mineral composition
Describe the formation of an oxbow lake
A meander caused by Weathering of soil will have the sediment in the river erode away. As eroded material builds up in the beginning and end of a meander due to Deposition the section of river becomes separated and is considered an Oxbow Lake.
The diagonal movement of sediment on the beach is due to this phenomenon
Long shore drift
Stalactites and Stalagmites form
Chemical
