Satellite Maps and Topographic Maps lvl.2

The image above shows a bay, a coastal body of water that directly connects to a larger main body of water, in Sydney, Australia. What is the most likely reason for the creation of the bay?

• Coastal deposition by ocean waves dropped off sediment on the coast creating a bay.

• A hurricane destroyed the coast creating the bay.

• Coastal erosion by ocean waves carried the sediment away creating a bay.

• A glacier bulldozed the coastline creating the bay and cooling off the ocean.

The image above shows sand dunes, hills of sand, in a desert. Sand dunes are constantly changing shape and location. What process of erosion is responsible for these changes?

• Animals change the sand dunes by carrying the sand dunes away.

• Rain from the desert carries sand particles to new locations.

• Wind carries sand particles to different locations.

• A river cuts through the desert and carries away sediment as it moves through.

The following image is of a crater in Arizona. Scientists predict a change in the shape of the crater will occur over time. What will most likely happen to the crater as time goes on?

• There will be no change.

• Erosion will break down parts of the crater, while weathering will carry the broken sediment away, causing the crater to decrease in size.

• Weathering will break down parts of the crater, while erosion will carry the broken sediment away, causing the crater to increase in size.

• As it rains, rainwater will collect in the crater. This will cause it to fill up with water and eventually become a small lake.

A satellite image of an area in Florida shows a river with slight bends along its length. A second satellite image taken of the same area 10 years later shows the same river with a different course. What is the best explanation for the difference in the shape of the river's course between the two satellite images?

• Wind blew waves across the water surface, eroding away the bank on one side of the river until the river's course changed its shape

• Regular freezing and thawing of the river split the soil along the river banks, changing the shape of the river

• Water eroded the banks of the river and deposited the eroded soil on opposite banks, causing the river to form tighter bends

• Acid rain chemically weathered the banks along the river, forcing the river to wind back and forth

A student is drawing a topographic map. They want to be able to illustrate all parts of the mountain. How would they draw contour lines to demonstrate steepness on their map?

• The student will need to draw lines close together to represent the steeper slopes and further apart lines to represent gentler slopes.

• The student will need to draw lines close together to represent the gentler slopes and further apart lines to represent steeper slopes.

• The student will need to draw lines more north to represent the steeper slopes and more south to represent gentler slopes.

• The student will need to draw thicker lines for steeper slopes and thin lines for gentler slopes.

A satellite image of a river is provided.

The river shown in the satellite image is carrying sediments in which direction?

• From south to north

• From southwest to northeast

• From northwest to southeast

• From east to west

A family wants to go hiking. The use a topographic map to mark out their journey. The want to take the easiest path possible. The family noticed Path B to C is about the same distance as path E to N. Which of the path would be the easiest, gentlest path for the family to take.

• B to C because it is less steep.

• E to N because it is more steep

• They are no different from each other

• B to C because it is more steep

What is the difference in elevation between Point X and Point Y?

• 120 m
• 240 m
• 360 m
• 340 m

Provided is a topographic map of a hill with contour lines drawn showing elevation in meters.
The steepest slope on this hill can be found on the side that is facing which direction?

• Southwest
• Northeast
• Northwest
• Southeast
