Exploring Erosion and Topographic Maps

Dr. Mike from Oxbow Meadows introduces the concept of erosion and demonstrates it using a model of a river. He encourages students to make observations and think about how water speed affects erosion. The video explains topographic maps, focusing on how elevation lines indicate slope steepness. Students are tasked with predicting erosion at different points on a map, using their understanding of topographic features.

What is the main topic of the video presented by Dr. Mike?

• Weather patterns

• Erosion

• Plant growth

• Animal habitats

What is a topographic map?

• A map showing plant distribution

• A map showing animal habitats

• A map showing weather patterns

• A map showing elevations

What does an elevation of 10,000 feet mean?

• The height of a building

• The depth of a river

• The height above sea level

• The distance between two points

What do closer lines on a topographic map indicate?

• A flat area

• A valley

• A gentle slope

• A steep slope

What do lines that are farther apart on a topographic map indicate?

• A plateau

• A gentle slope

• A cliff

• A steep slope

Which point is likely to have more erosion, Point A or Point B?

• Both points equally

• Neither point

• Point B

• Point A

Why would Point A have more erosion than Point B?

• It is closer to the water source

• It has more vegetation

• It is at a lower elevation

• It is at a higher elevation
