Topographic and Satellite Maps Test Review

The satellite image below shows a portion of the Namib Desert in Africa. This is an ancient, sandy desert with dunes that can be up to 305 m tall. The Namib Desert extends inland from the Atlantic Ocean between 80 km and 200 km and receives only 5 mm to 76 mm of rain each year.

A satellite picture of this same area taken weeks before shows that the shape and location of some sand dunes have changed. Which of these most likely caused the changes in the dunes?

• Ocean waves

• Flowing rivers

• Blowing wind

• Crustal uplift

The satellite image shows a ship channel between South Padre Island and Boca Chica beach in South Texas.

Sand is sometimes removed from theship channel through a process called dredging to make it easier for ships to travel through. Recently sand from the bottom of the channel was moved to are beaches. Without this transfer of sand, what would most likely occur in this area in the future?

• The ship channel would become deeper, and the island would move west toward the mainland.

• The ship channel would become shallower, and the beach would become narrower.

• The ship channel would become narrower, and the island would become completely covered with water.

• The ship channel would become wider, and the island would sink into the Gulf of Mexico.

A student stands at the point marked X on the topographic map below.

What height in meters must the student climb in order to reach the top of the hill? ( type only the number answer, do not add meters)

The points labeled W and Y on the topographic map below show the campsites of two families. Each family hiked to the elevation on the map marked X. The arrows show the paths taken by both families. What was the change in elevation, to the nearest ten meters, for the family that took the steepest path to Point X? (type only the number, do not add meters)

This satellite photograph shows an area in Alaska after a fire occurred. Which statement best describes the most likely effect the fire had on the river in the 12 months after it occurred?

• Less sediment flowed into the river because the fire heated up the soil and made it drier.

• The amount of vegetation increased and less sediment flowed into the river because the fire produced ash that mixed with the soil.

• More sediment flowed into the river because the fire destroyed most of the vegetation holding the sediment in place.

• More sediment flowed into the river because the fire disrupted animal habitats and caused animals to leave the area.

The topographic map shows the location of a park ranger at Point X when a message is received that an injured hiker needs help at Point Z. Which of these is closest to the difference in elevation between the locations of the ranger and the injured hiker?

• 2,050 m

• 450 m

• 910 m
