a group of small streams that flow together into slightly larger streams
What is a tributary
100
a funnel-shaped depression in the surface caused by dissolving of underlying rocks
What is sinkhole
100
Erosion of a valley by a stream
What is downcutting
100
a stream with a channel that curves or loops back and forth on a wide floodplain.
What is Meandering Stream
100
When a glacier cannot hold all of its load, it deposits part of it by plastering it onto the bedrock beneath the glacier
What is Glacial Till
200
the area from which all the rain that falls eventually flows to the same final destination, usually the ocean
What is the drainage basin or watershed
200
the breaking down of rocks by chemicals
What is weathering
200
The volume of water passing a point along the river in a unit of time
What is stream discharge
200
What are the steps of the hydrologic cycle?
What is Precipitation, Condensation, and Evapotranspiration
200
A mound or ridge of mainly glacial till deposited by the direct action of glacial ice
What is moraine
300
a major river red by a small number of fairly large tributaries; usually tree-like drainage pattern
What is a trunk stream
300
water that is contained in pore spaces and fractures in sediments and rocks beneath Earth's surface
What is groudwater
300
the slope of a stream or river expressed as a loss in elevation of the stream or river with distance downstream
What is gradient
300
The flat, low-lying valley bottom surrounding the channel that fills with water when the river overflows.
What is floodplain
300
This ice sheet rearranged the course of many rivers in North America
What is Pleistocene ice sheet
400
a number of small channels that branch off from the main river near the river's final destination
What is a distributary system
400
Main causes of flooding are
What is heavy rains and development on poorly drained parts of the floodplain because water drains off at a very slow rate
400
Where are high-gradient streams usually located?
What is the headwater areas of river systems
400
a crescent-shaped body of standing water situated in the abandoned channel of a meander.
What is an Oxbow Lake
400
Melting of the lower areas of glaciers in summer produce enormous volumes water; together with rainwater from summer storms that flows across the glacier and finds its way through the glacier through fissures and holes in the ice.
What is meltwater
500
What is the one thing all parts of a river system have in common?
What is it flows downhill
500
Landforms that develop from the dissolution of underlying carbonate rocks
What is Karst terrain
500
what are very small streams usually called
What is brooks or creeks
500
When does flooding occur on low-gradient streams?
What is when the stream channel cannot contain the discharge of water that is passing through it.
500
How did the Great Lakes, the Finger Lakes and Lake Champlain form?
What is ice sheets erode out wide and deep depressions in the bedrock which fill with water to become lakes.
