What kinds of landforms are shaped by erosion?
Canyons or caves
100
What is topography?
is the shape and size of the land features on Earth's surface
100
What is index contour?
a thicker contour line that often has an elevation label.
100
What are the conditions for a glacier?
areas where it is cold enough for ice to stay cool year round.
100
What is remote sensing?
is the process of gathering and analyzing information about an object without physical contact with the object
200
What causes sinkholes?
acidic groundwater
200
What are contour lines?
connects points of equal elevation on a topographic map
200
What is loess?
thick deposits of windblown, fine- grained sediment
200
What is a glacier?
is a large mass of moving ice that forms by the compacting of snow by natural forces
200
What is GPS?
is a network of satellites orbiting earth
300
How does erosion erode sea caves?
waves can cut deeply into the cracks and forms large holes, as the holes erode, they form sea caves.
300
What is a scale?
shows the relationship between the sizes and distances shown on the map and the actual measurements on Earth's surface
300
What is a creep?
the extremely slow movement of material downslope. (also Alex)
300
What is glacial drift?
is the general term for all of the materials carried and deposited by a glacier.
300
What is GIS?
is a program used to view and make images and maps.
400
Waves and currents erode the shoreline forming what?
bays, inlets, headlands, sea cliffs, etc.
400
The difference in elevation between two contour lines is called what?
contour interval
400
What is slope?
measures steepness from one point to another.
400
What is an arête?
a sharp ridge that forms between two cirques that are next to each other
400
Why do we use remote sensing?
because it is easier to view images from the air rather than the ground
500
The ocean deposits what?
sand, rock, dead coral, and shells.
500
A map that shows the different rock types in an area is a what?
Geologic map
500
How do kettle lakes form?
They form when chunks of ice are deposited by a glacier and glacial drift builds around ice blocks, when the ice melts, the lake forms.
500
What is a continental glacier?
are thick sheets of ice that may spread over large areas.
500
Where were the first aerial images taken from?
they were taken by hot-air balloons in 1858
