As the velocity of a stream transporting pebbles, sand, silt, and clay decreases from 30 cm/s to 0.1 cm/sec, some sediment deposition will occur. Which choice below best describes the sediments that will be deposited as a result of the decrease in stream velocity?

1. pebbles, sand and some silt 2. clay and some silt 3. pebble, sand, silt, and most of the clay 4. only some sand and clay

Which agent of erosion most likely produced this valley’s shape?

1. wave action 2. moving ice 3. blowing wind 4. flowing water

Transported sediments are usually deposited at locations in which

1. the freeing and thawing of water occurs 2. the chemical breakdown of rocks occurs 3. a decrease in the speed of the agent of erosion occurs 4. an increase in the physical weathering of rocks occurs
