A rain storm causes a large amount of water to flow through the river in a very short time. Which size sediments would you most likely find at each location, X, Y, and Z?

• where the water runs slower, and finer clay particles at location Z.

• smaller rocks like sand and gravel at location Y, Y where the water runs slower

• cobbles and pebbles at location X, where the water runs faster

• All of the above

You  nd some soil that is mostly made of clay and silt, but no sand. How might this soil have formed?

• Silt, clay, and organic material settled out of slow-moving water

• A fast-moving stream washed away all the sand.

• Wind blew all the sand away, leaving behind the silt and clay particles

• Slow-moving water carried the sand downstream and left behind the silt and clay
