Satellite

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

Provided is a satellite image of a glacier as it moves down a mountain and into the bay.
What is the general direction of movement of the glacier?

• North
• South
• East 
• West

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

What would be the most likely way this coastline would change over time?

• A fire could destroy the vegetation
• The waves could erode the beach
• The beach would grow due to deposition
• The beach will disappear due to plate tectonics

These images compare the same stretch of coastline.  What is a possible reason for the change?  

• A fire destroyed the beach and surrounding area
• Overtime, water eroded away much of the land
• A major catastrophe such as a hurricane or tsunami destroyed the area
• The beach and land went through a sever drought
