A stream flows from a steep mountain onto a flat plain and slows. What happens to many pebbles in the stream?

Floodwater leaves the main river, spreads over a field, and slows. What happens to fine mud in the water?

Waves move sand until they slow in shallow water near a beach. What does the sand do there?

A river splits into several channels at its mouth and slows. What does this slowing cause?

Sand has piled up behind this boulder on a windy beach. Why did the wind drop the sand there?

A fast creek enters a quiet pond and slows suddenly. What happens to the gravel it carries?

In a stream table, water carries sand down a tilted tray. A student wants the water to drop more of its sand. What change should the student make?

People build a dam far up this muddy river. The dam traps much of the mud the river carries. What will most likely happen to the land the river builds at its mouth?

Rock on a hillside is broken down, moved by a stream, and later left in a valley. Which order shows how this happens?

People plant beach grass and put up sand fences along a beach. How do these help protect the beach?

A glacier slowly melts at its lower edge. What happens to the rocks and gravel frozen inside the ice?

After a heavy rain, a muddy stream like this one flows much faster than usual. What can the faster water do?

Wind blows sand across a dry field toward a low fence. Where will most sand pile up when the wind slows?

Floodwater spills out of a river onto a wide, flat field. Why does the water slow down there?

A river brings mud into a calm harbor, and the mud keeps settling on the bottom. What problem can this cause for ships over many years?

Waves wash sand through a narrow inlet into a quiet lagoon. Where will the sand settle?

A stream carries gravel, sand, and clay from a hillside into a flat valley. As water slows, what settles closest to the hillside?

A river leaves mountains and slows across a plain. Which particles settle first, and which travel farthest?

A stream enters a pond carrying gravel and fine silt. What is deposited near the stream inlet, and what travels farther?

Wind moves large sand grains and tiny dust across dunes. When wind slows behind plants, what settles first?

A river carries sand and mud. Why does the river drop the sand and mud when its water slows down?
