Sub-tropical Desert: |
Formed by sub-tropical high pressures. |
|
Trade Winds Desert: |
Created by trade winds. |
|
Mid-Lattitude Desert: |
Influenced by the sub-tropical high and inland areas are a far distance from oceans. Caleld continentality. |
|
Monsoon Desert |
Experiences seasonal precipitation increases. |
|
Coastal Desert |
They occur where cold ocean currents corder a warmer land mass. The water is too cold to evaporate so the region stays dry. |
|
Orographic Desert |
Where the dominant winds in a region are blocked by mountain ranges. The moisture is lost as it is precipitated on the mountain. |
|
Polar Desert |
Where the temperatures are so cold that freezing level is rarely met. |
|
Amount of Wind Directions needed to form sand dunes. |
One |
|
Straight Channel |
Rarely forms in nature, forms in short distances along fault lines, or bedrock. |
|
Braided Stream |
Multiple interconnected shallow channels produced by an inability to transport a large stream load. |
|
Meandering Stream |
Has a single, winding channel that twists and curves as it flows. |
|
Where does degradation occur? |
When the stream channel removes sediment from the channel. |
|
Where does aggradation occur? |
Occurs when the stream can't transport any more sediment and deposits it. |
|
How to calculate Hydraulic Radius? |
Hydraulic Radius = |
|
Stream Orders: |
First order: no branches or tributaries. 2,3= large flow surges |
|
Backshore |
Backshore: only impacted by large storms. Foreshore: Affected by daily tides |
|
Offshore: Berm: Dunes: |
Offshore: Outer extent to wave action. Berm: Area in backshore above high water line Dunes: Furthest away from water |
|
Daytime wind circulation: Nighttime wind circulation: |
Daytime: Low onshore, High offshore, winds blow onshore. |
|
Spring Tide: |
Spring Tide: Occur when moon and sun are aligned (large tidal range) |
|
Longshore movements: |
Swash onto the beach and backwash out transports sediment along the beach in the direction of the longshore current. |
|
What happens to irregular coastlines over time? |
They develop caves and eventually stacks. |
|
Location of glaciers and what they are called: |
- |
|
Ablation: |
Where the mass of ice is removed. |
|
Zone of Accumulation |
The supply of ice and water for the glacier. |
|
Terminus |
- |
|
Erosional Landforms |
Cirque: Bow like depression U-Shaped Valley: Glacial Trough Arete: Ridge |
|
Depositional Landforms |
