Exploring Topographic Maps and Satellite Views

This video tutorial covers Texas Essential Knowledge and Skills 8.9C, focusing on interpreting topographic maps and satellite views to identify land and erosional features. It explains weathering and erosion processes, how to read topographic maps, and interpret satellite images. The tutorial includes sample questions and emphasizes using Cornell notes for effective learning.

__________ is the process by which wind, water, or ice wear down surfaces and or rocks over time

• Corrosion
• Abrasion
• Erosion
• Weathering

_______ is the process in which you move sediment from one location to another

• Deposition
• Transportation
• Erosion
• Weathering

__________ is the process by which sediment in is dropped off and compiled (stacked up)

• Erosion
• Accumulation
• Dissolution
• Deposition

What is the main difference between weathering and erosion?

• Erosion involves the movement of material, while weathering breaks it down.

• Weathering involves the movement of material, while erosion breaks it down.

• Both weathering and erosion involve the chemical breakdown of rocks.

• Weathering and erosion are the same processes under different conditions.

What feature is formed when a river deposits sediment into a sea or ocean?

• Delta

• Canyon

• Island

• Mountain

Contour lines tell us the __________ of an area (how high)

• temperature
• elevation
• width
• depth

What is the elevation of the line in-between 100 and 200

• 225
• 175
• 150
• 125

What does an index contour line represent on a topographic map?

• The highest elevation point

• A significant change in elevation

• The lowest elevation point

• A water body outline

How do you determine the elevation at a point between two index contours?

• By subtracting the contour interval from the higher index contour

• By adding the contour interval to the lower index contour

• By averaging the elevations of the nearest index contours

• By calculating the difference in elevation between the index contours

What does a contour interval indicate on a topographic map?

• The distance between two mountains

• The depth of a body of water

• The change in elevation between contour lines

• The length of the contour lines
