Changes in Landforms

What is the BEST explanation for how the steep walls of a canyon were formed?

• sediments were deposited in the bottom of an ancient lake

• an ancient earthquake caused the land to split apart

• the walls were weathered and eroded by a river

• the canyon was created when lava pushed the sea up

What is the BEST explanation for how a valley is formed?

• earthquakes formed the valley along a California fault line

• deposition of sediment flowing down the river formed the valley

• lava flows from ancient volcanoes in the canyon formed the valley

• flowing water and runoff that flowed down the hills formed the valley

Following a recent natural event, scientists recorded the following observations of what happened:

“A large amount of sand was deposited over a mile inland from the shoreline. Large amount of debris from buildings, trees, boats, and cars were also dropped well away from the beach.”

A scientist observed the rock below in the snow-covered mountains.

What most likely explains the large cracks in the rock?

• The cracks were caused by erosion when river water flowed by it.

• The cracks were caused by weathering when water froze in the cracks.

• The cracks were caused by weathering when acid rain fell on it.

• The cracks were caused by erosion when a heavy snow fell on it.

The model below shows the direction of water flow in the inlet as the tide rises.

What is the most likely effect on the estuary as the tide rises?

• The ocean water brings in sediments and sea life that help feed life in the estuary.

• The ocean water in the inlet moves very fast and removes sediment from the estuary.

• The ocean water decreases the salt level in the brackish water in the estuary.

• The ocean water lowers the water level in the estuary and exposes the marsh area.
