A
The middle inner layer of earth
Core
The breakdown of rock into smaller pieces.
Weathering
Loosens and transports sediment by gravity, wind, water, or ice.
Erosion
Alpine
Name of the landmass before the continents drifted apart.
Pangea
The reason why plates move.
Convection Currents
Acid rain and oxidation are examples of what kind of weathering?
Chemical Weathering
It creates sand dunes and rock arches.
The process of physical weathering and erosion by ice.
Glaciation
This can occur at any plate boundary to release stress.
Earthquake
The Appalachian and Himalayan Mountains were formed by which type of boundary?
Convergent
Type of weathering caused by living things.
Biological weathering
It creates landforms such as valleys, canyons, caverns or floodplains.
Water erosion
The type of valleys glaciers form.
U-shaped valleys
Beaches change shape and size because of what erosion?
Wave erosion
This is created when a oceanic plate collides with a continental plate.
Subduction zone
The grinding and scraping by wind, water or human activity.
Abrasion
It is a curve or bend in a stream bed.
Landforms composed of glacial till deposited primarily by glacial ice.
Moraines
River erosion can move all sizes of ______________.
Sediments
A plate boundary that moves away to each other.
Divergent boundary
Plants, algae, lichens, fungi, and bacteria can dissolve rocks for nutrients.
Chemical-biological weathering
Triangle-shaped area at the mouth of a river and where deposition occurs.
Delta
Created by glacial weathering and is evidence of glacial activity, specifically abrasion.
The material that is produced by explosive volcanoes.
Pyroclastic material.
