A glacier deposits till at the edge, forming a ridge called:
Glacial Moraine
The process of dirt and sediment being dropped
Deposition
The process that combines Oxygen with other elements to cause oxidation (copper turning green)
Chemical Weathering
What is a RAPID downhill movement of soil, rocks and boulders?
landslide
Ice-wedging in rocks causes mechanical weathering by what? (how does it work)
freezing and thawing of water
What is a mixture of sediments deposited by a glacier?
TILL
What is the eerie, out-of-shape look of the land on the side of a mountain caused by slowly moving rock and soil?
Creep
Wind, water and ice are agents of what?
The movement of weathered material or sediment from one place to another is what?
Erosion
What are the 2 most important factors in determining the rate of weathering?
type of rock and environment
Landslides, mudflows, slump and creep are all examples of what?
Mass movement
What causes rocks and other materials to move downhill (MASS MOVEMENT)
Gravity
What is a broad, winding stream is called?
Meander
What is a stream that flows out of a narrow canyon or at the foot of mountains and deposits sediment?
Alluvial Fan
The RAPID downhill movement of water, rock, and soil
mudflow, mudslide
Two processes where glaciers erode the land by either:
1. Picking up rocks
2. Dragging them along the bottom
1. plucking
2. Abrasion
How does groundwater erosion occur?
seeps into the ground with other corrosive elements to break down limestone
When a meander deposits enough sediment on one side and erodes the other, it can form this:
Oxbow Lake
Glaciers can only form when...
more snow falls than melts and it stays cold
Tiny to small/medium grooves in soil and dirt (2 answers)
rills and gullies
Which is evidence that an area between mountains was once covered by a glacier?
U-shaped valley
Two types/kinds of glaciers found:
Alpine/Valley Glaciers and Continental Glaciers
The process of wind, animals, rain, dirt or other debris breaking down rocks and landforms
Physical Weathering
delta
The sediment deposited at the edge of a glacier/glacier breaking off and melting leaving sediments is called
Kettle Lake
