Weathering
The Breakdown of rocks
Weathering
The number one agent of erosion
water
A large deposit of sand by the wind.
A Dune
A Curve in a river
A Meander
Scratches made in the bedrock by glaciers.
Striations
The breaking down of rocks into smaller pieces
physical or mechanical weathering
The agent that is most common in a hot, dry climate.
wind erosion
Where most running water eventually deposits sediment.
On the ocean floor or bottom
Dissolved sediment in a river is carried this way.
A Solution
These glaciers round off mountain tops.
continental glaciers
When rocks breakdown and create new substance/types of rocks
Chemical Weathering
The primary force behind all mass movements.
Gravity
The sediment that builds up in a delta create this.
Islands
The area drained by rivers and its tributaries.
A Watershed
Long, smooth, canoe-shaped hills of till.
drumlins
When oxygen reacts with minerals changing them into iron oxide.
Oxidation
This agent of erosion produces U-shaped valleys.
Glaciers
Fill in the blank:
Larger, more dense and more ________ sediments settle faster to the bottom of still water.
Round
A cut off meander.
An Oxbow Lake
These are large boulders transported by glaciers
glacial erratics
When wind scrapes or wears away rock
abrasion
This provides the energy for rivers and glaciers.
The Sun
Sediment builds up on this part of a bend in a river.
The Inside
Fan shaped deposits at the mouth of a river.
A Delta
Bowl shaped formations where valley glaciers begin to form
