Lesson 1.2 Topographic and Geologic Maps - Mastery

What do contour lines represent on a topographic map?

• Areas of equal elevation

• Areas of equal temperature

• Areas of equal precipitation

• Areas of equal vegetation

What do closely spaced contour lines indicate on a topographic map?

• Steep slopes

• Flat areas

• Valleys

• Rivers

What is the contour interval on a topographic map?

• The distance between two contour lines

• The distance between two index contours

• The distance between two geologic formations

• The distance between two fault contacts

What are index contours on a topographic map?

• Darker or wider contour lines representing round numbers of elevation

• Lines connecting points of equal elevation

• Lines indicating areas of equal temperature

• Lines indicating areas of equal precipitation

How are geologic maps created?

• By observing and collecting rock samples from Earth's surface

• By studying weather patterns

• By analyzing satellite images

• By measuring seismic activity
