All About Glaciers
100
Velocity and stream discharge are the two influences of what stream process.
What is stream erosion?
100
rock/sediment that halts ground water flow due to low porosity or permeability.
ex) shale, clay
What is an aquitard?
100
A term for all the places on earth where water is in it's solid form, includes polar regions, glaciers, and high altitude mountains.
What is the Cryosphere?
100
Refracted waves hitting the coastline at an angle, which pushes water to form currents parallel to the coastline. Can produce spits, and baymouth bars.
What are longshore currents?
100
Fragments of rock transported and then deposited by a glacier.
What is till?
200
Draw a trellis vs dendritic drainage pattern.
200
The level in which a rock is able to pass fluid through its pores.
What is permeability?
200
The change in global averaged sea-level that would occur if a given amount of water or ice was added.
What is sea-level equivalent (SLE)
200
Highest point of normal wave activity along a beach.
What is a berm crest?
200
A glacial deposit that is shaped like an inverted spoon in the direction of glacial travel.
What is a drumlin?
300
What are three ways streams carry sediment?
Bed load, suspended load, dissolved load
300
What is the difference between the vadose zone vs phreatic zone.
Vadose -> region above water table, unsaturated
phreatic -> region below water table, saturated with water.
300
Permanently floating ice connected to land mass.
What is an ice shelf?
300
Pattern of highest tides, produced by the alignment of the Earth, sun, and moon.
What are spring tides?
300
A steep-sided, half-bowl-shaped recess carved into a mountain by a glacier, at the head of a valley.
What is a Cirque?
400
Draw the hydrological cycle.
Include the following terms: Evaporation, Precipitation, Transpiration, Runoff, Infiltration, Glaciers
400
What is the difference between a gaining stream & losing stream?
400
Upper zone of a glacier that is the passively "riding along" due to friction.
What is the rigid zone?
400
Semi-enclosed bodies of seawater that are connected to the ocean, and diluted with freshwater from the land.
What is a Estuary?
400
Elongated mounds of till that forms along the sides of a valley a glacier has passed through.
What is a lateral moraine?
500
Draw the formation process of an oxbow lake.
include and define meandering streams and meander cutoffs
Meandering streams-> streams that flow faster along outside of bends, and more slowly along the inside
Meander cutoffs-> form when a new, shorter channel cuts through the neck of a narrow meander
500
Aquifer that has a completely filled water table, and is separated from the surface by a confining layer.
What is a confined aquifer?
500
The ice sheet which covered North America during the last ice age, melted about 18,000 years ago causing 120 meters of sea level rise.
What is the Laurentide ice sheet?
500
Rock walls designed to prevent the entrance of a harbor filling with sand.
What is a Jetty?
500
What are Earths current two main glaciers?
100 pt bonus (what are their SLE)
The Greenland (7.2 SLE) and Atlantic (58.3 SLE) ice sheet.
