What's the Weather?

100

The name of the sphere containing all rock and ground material

Geosphere

100

What are the two types of weathering?

Mechanical and Chemical

100

In every coastal region, ocean deposition creates

Beaches

100

Formed as soft rock erodes at the coast and hard rock remains, jutting out from the coast line

Headland

100

Rock breaks into smaller pieces

Mechanical

200

What is the composition of the A, B, and C horizons of ground composition

A= top soil/Humus B= Subsoil, C= Bed rock

200

Define Erosion

Sediment carried away by an outside force

200

Deposition at the end of a river will form what?

A Delta

200

What are the two actions a glacier can perform to change a land

Abrasion and Plucking

200

An underground cave forms

Chemical

300

What is a fast way the geosphere can be changed drastically

Landslide or Mudslide

300

Earthworms are considered _____ because they break down organisms in the soil producing Humus

Decomposers

300

These can form on both beaches are in deserts due to wind erosion

Sand Dunes

300

When sea arches fall due to wave action they form

Sea stacks

300

Pressure changes on the surface causes a sinkhole

Mechanical

400

What are the two materials you will find in Humus

Decaying organisms  and Dead plants

400

What kind of rock is easily broken down through chemical weathering?

Limestone

400

Formed by the pull of gravity on sediment in a mountain valley

Alluvial Fan

400

What are the three landforms that can be created through wave deposition

Sandbars, Spits, Barrier Island

400

Rock sits in a body of water and forms bubbles

Chemical

500

What is Uniformitarianism?
Geologic processes that operate today also happened in the past

500

The main factor that can determine the rate of weathering in a rock

The mineral composition

500

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.

500

The diagonal movement of sediment on the beach is due to this phenomenon

Long shore drift

500

Stalactites and Stalagmites form

Chemical
