weathering in which a chemical change takes place in the rock or rock particles
What is chemical weathering
100
the placement of sediment to produce landforms
What is deposition
100
a long ridge of stratified drift left behind when a glacier retreats
What is esker
100
global positioning system; a network of orbiting satellites that constantly broadcasts radio signals allowing anyone on Earth with a GPS receiver to determine his or her altitude, longitude, and latitude
What is GPS
100
a structure made of sediment dropped by a glacier
What is moraine
200
a natural geological process that makes minerals, rocks, and landforms
What is constructive smoking
200
a natural geological process that wears down landforms, rocks, and minerals, and carries the bits and pieces to different places on land and sea
What is destructive force
200
an area where the wide mouth of a river meets the tidal waters of an ocean
What is estuary
200
a layer in a soil profile
What is horizon
200
a region where glacial melt has created streams that dry up and deposit sediment
What is out wash plain
300
a line on a map that connects places that have the same elevation above sea level
What is contour line
300
long mounds of glacial drift that run parallel to the path of the glacier's retreat
What is drumlin
300
the mechanical breakup of rock caused by the expansion of freezing water in cracks and crevices
What is frost wedging
300
a large mound of stratified drift left by a retreating glacier
What is kame
300
in soil, a network of holes that lets air and water circulate
What is pore spaces
400
the difference in elevation between contour lines; shows how much you would ascend or descend every time you went from one contour line to another.
What is contour interval
400
the physical movement of weathered materials, as by water, wind, ice, and so on
What is erosion
400
a geographic information system; a computer system that lets scientists store, share, analyse, and display vast amounts of geographic information
What is GIS
400
the down slope movement of sediment because of gravity
What is mass wrestling
400
surface soil, including the organic layer in which plants have their roots
What is topsoil
500
a map that shows the different elevations of an area of land; a topographical map
What is contour map
500
individual boulders dropped by a glacier that are often made of igneous and metamorphic rock
What is erratic
500
a huge mass of ice that does not completely melt over the course of a year
What is glacier
500
the physical disintegration of rock or into smaller fragments
What is mechanical weathering
500
the wearing down of rocks and soil by chemical and physical processes
