How does erosion by groundwater create landforms?
Acidic groundwater dissolves rock and creates caves or sinkholes
100
What landforms do wind erosion form?
Dunes, loess, abraded rock, desert pavement
100
Dunes
Mounds of wind-deposited sand
100
What if the difference between an aerial and satellite image?
Aerial images are usually taken from airplanes, satellite images are usually taken by space satellites that orbit earth
100
How do you find the difference between the beginning and end elevations on a topographic map?
Subtract the smaller elevation from the larger elevation
200
When do rivers form deltas?
When sediment builds up from rivers/streams depositing their load
200
What are contour intervals
The difference in elevation between two contour lines
200
Loess
Thick deposits of wind-blown, fine-grained sediment
200
What does a geologic map show?
Rock types and ages
200
What is remote sensing?
The process of gathering and analyzing information about an object without physical contact with the object
300
Formation if floodplains
Streams flood, and a layer of sediment is deposited over flooded land, when many layers build up, it forms a flat floodplain
300
What is GIS
A program used to view and make images and maps

What is the difference between GPS and GIS
A GPS is a network of satellites orbiting Earth, GIS is a program used to make images and maps
400
Definition of GPS
A network of satellites orbiting earth

How is GIS used?
It can be used with many sources of information: different kinds of maps, images, and data can be combined or layered using GIS
400
Glacier
A large mass of moving ice that forms by the compacting of snow by natural forces
400
What is the difference between contour intervals and contour lines?
Contour intervals are the difference in elevation between two contour lines, contour lines connect points of equal elevation

Scientist can study changes to land features by comparing (past/future) images with recent ones. Choose the correct answer
Past

Conditions that trigger mudslides
When a large amount of water mixes with soil and rock
500
How do glaciers affect valleys
The glacier widens and straightens valleys into a broad u-shape
500
Glacial drift
The general term for all of the materials carried and deposited by a glacier
500
What are some symbols used to represent features on a topographic map?
Points, lines, and area symbols
