Understanding Stream Flow on Topographic Maps

What does the tip of the V shape formed by contour lines indicate when determining stream flow?

• The direction the water is flowing towards

• The source of the water

• The speed of the water flow

• The depth of the stream

Why can't water flow from a lower elevation to a higher elevation?

• Because of gravity

• Because of wind resistance

• Because of the Earth's rotation

• Because of the water's temperature

When using contour lines to determine stream flow, what is the significance of the V shape?

• It shows the width of the stream

• It marks the end of the stream

• It indicates the direction of the water flow

• It shows the depth of the stream

In the example of Maple Stream, which direction is the stream flowing?

• Southeast

• Northwest

• Southwest

• Northeast

What is the primary purpose of using both contour lines and elevation data on a topographic map?

• To find the stream's temperature

• To accurately determine the stream's flow direction

• To determine the stream's depth

• To measure the speed of the stream
