What is a landform at the mouth of a river, formed from the deposition of sediment carried by the river as it flows into a body of water.
Delta
What kind of landforms are created by wind erosion in desert regions?
Dunes
As glaciers move and eventually melt, they deposit materials like rocks and sediment they picked up along the way
Glacier Drift
How can you identify a steep slope on a topographic map?
The contour lines are close together.
What does GPS stand for, and what does it do?

What is the contour interval on a topographic map?
The vertical distance between contour lines.
What does GIS stand for?
Geographic Information System
How are caves created by erosion?
Groundwater erodes underground rocks
What is relief?
The difference from the highest point to the lowest point.
What are fine, silt-like sediments transported and deposited by wind, often forming large, fertile plains over time.
Loess
What is the contour index?
Every fifth line is made darker
What is the benefit of using a satellite image
Satellites provide detailed images over time, and allow for a view of a larger area.
