Exogenic Processes
Two types of glaciers
Alpine and continental
Continental glaciers characteristics
Carved Great Lakes, fjords
Soil
Created by weathering of rock and decomposing organic material
Moraine
Debris left over after glaciers melt
Arid is
Desert
Glacier
Very thick, slow moving sheets of ice that build up over time
Types of erosion
Water, wind, glaciers
2 processes of exogenic processes
Weathering and erosion
Terminus
Where glacier ends (Alpine) and it starts to melt. Forms a moraine
Loess
Yellowish wind blown soil from China that gets in the atmosphere
Arid rain
<10 inches per year
Soil creep is
A lesser slope and gradual slide
Examples of mechanical weathering
Frost wedging and root growth
Desert Pavement
Hard rocky cement-like floor of desert
Continental glaciers are
Ice sheets/masses
Floodplain
Low area adjacent to river where there is flooding on a regular basis
Gravity transfer
Mass movement
Types of weathering
Mechanical, chemical, gravity transfer
Exogenic processes
Modify the landscape created by endogenic processes
Landscape change example
Mountain, hill, plateau, mesa, butte, flat
Alpine glaciers are
Mountains
Exogenic processes occur
On the exterior of the Earth
Example of chemical weathering
Oxidation and acid-rain
Mechanical weathering
Physical breaking of rocks
Longshore current
Picks up spool and stretches down beach
Steep slopes cause
Rock slides and mudslides
Wind erosion occurs at
Semi-arid/ arid areas
Delta
Silt deposited in mouth of river
Alpine glaciers characteristics
Slide down hillside and can turn v-shaped valleys into u-shaped valleys
Gravity transfer examples
Steep slopes and soil creep
Weathering
The breaking up of rock at or near the Earth's surface
Erosion
The movement of the weathered material
Chemical weathering
The rock is chemically weakened by a chemical change
