Class 8b: Desert and glacial landforms. Desert landforms Tend to be stark, barren (not much soil)
Types of Landforms Caused by Erosion & Deposition
 As glaciers travel over land, glacial ice can erode the underlying bedrock.  This erosion can happen by:  Plucking  Abrasion.
10.4. Erosion  Water, in either gas, liquid, or solid form can change the surface of the earth, it can even carve rock!  Erosion is the transportation.
Erosion and Deposition
Fluvio-Glacial Landforms. Fluvio-glacial landforms are landforms molded by glacial meltwater. There are 2 main fluvio-glacial features; 1)Outwash Plains.
Deposition. When transported material settles or comes to rest Caused by: running water, glacial ice, waves, or wind losing energy so they can no longer.

Glaciers We wouldn’t be here without them.. A Glacier is an accumulation of snow that is large enough to survive the summer melt. These large ice masses.
Mass movement & Glacial erosion
Glacial Erosion and Deposition. Erosion Glaciers have the capacity to carry huge rocks and piles of debris over large distances They grind out parallel.
Glacial Landscapes Glacier = large moving mass of ice. Glacier = large moving mass of ice. Glaciers erode, transport and deposit massive amount of sediment.

Presentation transcript:

Glaciers & erosion Glaciers can leave behind large boulders known as erratic. Glaciers can move lots of sediments that can carve striations or grooves into rocks.

Glaciers & Erosion Drift or till is all sediment that is deposited by glacial activity Moraine: ridge or pile of boulders, gravel, sand left at the end of a glacier Esker: sediment carried by water in channels of a glacier (outwash)

Running Water & Erosion Rivers with lots of energy can move lots of sediment and even large boulders. Fast water, large discharge, & a steep slope = high erosion Slow water, low discharge, & gentle slope = low erosion

Running Water & Erosion

Running Water & Erosion River meanders or bends in the river, shows how mature a river is.

Mass Movement & Erosion Mass movement is the downward transportation of weathered materials by gravity.
