Wed in the Ecoregions

Which of the following will most likely increase the amount of erosion that occurs on the banks of a river?

• Heavy rains on the mountain that is the river’s water source.

• High winds over the ocean to which the river flows.

• High temperatures increasing evaporation from the river

• Ice formation at the source of the river

The illustration provided shows exposed layers of sedimentary rock in the High Plains region of Texas. Which of the following best explains the uneven nature of the exposed rock layers?

• Different types of rock weather at different rates when exposed.

• Wind speeds vary greatly over time in this region of Texas.

• An ancient river deposited sediments at different rates over time.

• Glacier movement always creates uneven rock formations.

In Galveston, the beaches are often exposed to hurricanes originating in the Gulf of Mexico. It is reasonable to predict that hurricane activity may -

• create new rivers near Galveston.

• move sand from the beach to offshore sand bars.

• cause local earthquakes after the storm.

• create new river deltas along the beaches.

Rivers carry and deposit sediments all along their course. Where will the sediments made of the largest and heaviest particles be deposited?

• Near the start of the river where water travels fastest

• In locations where the river banks are the widest

• In locations where the river banks are the most narrow

• At the river’s mouth where the river meets the ocean
