weathering in which a chemical change takes place in the rock or rock particles
What is chemical weathering?
100
a natural geological process that wears down land forms, rocks, and minerals, and carries the bits and pieces to different places on land and sea
What is destructive force?
100
an area where the wide mouth of a river meets the tidal waters of an ocean
What is estuary?
100
a downslope movement of sediment because of gravity
What is mass wasting?
100
the sediment left behind by a glacial melt-water, in which the heaviest sediments are at the bottom, and the smallest and lightest are at the top
What is a stratified drift?
200
a natural force geological process that makes minerals, rocks, and landforms
What is constructive force?
200
long mounds of glacial drift that run parallel to the path of the glacier's retreat
What is drumlin?
200
a huge mass of ice that does not completely melt over the course of the year
What is glacier?
200
the physical disintegration of rock into smaller fragments
What is mechanical weathering?
200
long ridges of till marking the farthest advance of a glacier
What is terminal moraine?
300
the difference in elevation between contour lines; shows how much you ascend or descend every time you went from one contour line to another?
What is contour interval?
300
the physical movement of weathered material, as by water, wind, ice, and so on
What is erosion?
300
global positioning system; a network of orbiting satellites that constantly broadcasts radio signals allowing anyone on Earth with a GPS receiver to determine his/her altitude, longitude, and latitude
What is GPS?
300
a structure made of sediment dropped by a glacier
What is moraine?
300
sediment dropped directly by a glacier's edge
What is till?
400
a line on a map that connects places that have the same elevation above sea level
What is contour line?
400
individual boulders dropped by a glacier that are often made of igneous and metamorphic rock
What is erratic?
400
broad plains of till left by a retreating edge of a glacier
What is ground moraine?
400
a region where glacial melt has created streams that dry up and deposit sediment
What is outwash plain?
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
a long ridge of stratified drift left behind when a glacier retreats
What is esker?
500
a large mound of stratified drift left by a retreating glacier
What is kame?
500
in soil, a network of holes that lets air and water circulate
What is pore spaces?
500
the wearing down of rocks and soil by chemical and physical prowess
