At the end of the Rio Grande there is a delta. How do you think the delta formed?
the river cut through the solid bedrock of the valley
river deposited large amounts of sediment from land erosion

Which 2 processes best complete this diagram?
Compaction and Cementation
Evaporation and dissolving
Erosion and compaction
Melting and cooling
12
Plants can grow on the surface of some water, how do they later become fossil fuels?
dead plants sink to bottom and comsumed by decomposers
dead plants produce carbon, eaten by fish, then forms fossil
dead plants sink to bottom & get buried by sediment mil. yrs
dead plants buried for mil. yrs, form fossil& attract carbon
13
Which of the following best explains how these layers can become rock over many years?
Sand in the sediment melts and turns into rock
Changing water temp. turn sand in the sediment into rock
Pollution caused by humans turns sediment into rock
The weight of the water compacts the sediment into rock
14

Which of the following represent the circles on the maps?
Earthquakes, they occur on land and the ocean floor
Volcanoes, they occur near the equator
Floods, heavy rains can make riverbeds deeper & create delta
Landslides, they are all located near ocean coastlines
