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
