9. which sediment type moves most easily with water? sand, silt, and clay. small, fine silt and clay
10. what is the most effective method of sediment transport in rivers? sorted
11. what sediment types are commonly found near a river mouth?
12. what energy source can move pebbles uphill?
13. what happens to sediments as they’re transported over time?
14. what type of river flow can move large rocks?

Explanation:

1. Glacial movement carves valleys in mountainous areas through processes like plucking and abrasion.
2. Wind is responsible for forming sand - dunes as it transports and deposits sand particles.
3. Rivers change landscapes over time through erosion, carrying away sediment and shaping channels.
4. A canyon is a landform created by water erosion, often by a river cutting through rock over a long period.
5. Glaciers deposit sediment to create landforms like moraines. Moraines are accumulations of debris left behind by a glacier.
6. Coastal waves cause erosion of shorelines, wearing away rock and soil.
7. Wind in deserts transports and deposits sand, forming dunes.
8. Wind energy moves sand in a desert.
9. Small, fine - grained sediment types like clay, silt, and sand can be moved by water, with clay being the most easily moved due to its small particle size.
10. Sorted sediment transport is an effective method in rivers, where particles are separated by size and density during transport.
11. Sand, silt, and clay are commonly found near a river mouth as the river slows down and deposits sediment.
12. Human energy (e.g., in construction or mining) or mechanical energy (e.g., using machines) can move pebbles uphill. In natural processes, it is very rare for pebbles to move uphill without external force.
13. As sediments are transported over time, they can be sorted, rounded, and deposited in new locations.
14. High - velocity river flow can move large rocks as it has enough force to dislodge and carry them.
