Geography Vocabulary

3. - Hydraulic action occurs when the motion of water against a rock surface produces mechanical weathering. Most generally, it is the ability of moving water to dislodge and transport rock particles.
5. - the removal of weathered sediment or rocks by the wind, water, ice and sunlight.
7. - In karst study, the change of bedrock from the solid state to the liquid state by combination with water. In physical solution the ions of the rock go directly into solution without transformation. In chemical solution acids take part, especially the weak acid formed by carbon dioxide (CO2).
8. - One of three distinct process of air, water, ice and sunlight.
10. - is a process that soil and rock added to the land form or landmass.
11. - Attrition refers to erosion of rock particles through friction as they are moved from one place to another. The rock particles gradually become smaller and more rounded in shape as they are transported by wind and water.

1. - Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice, and/or by the force of gravity acting on the particle itself.
2. - Erosional movement of sediment continually held in the transport medium of air, water or ice.
4. pool - A deep basin excavated at the foot of a waterfall by the action of the falling water.
6. - A narrow valley between hills or mountains, typically with steep rocky walls and a stream running through it.
9. - Physical wearing and grinding of a surface through friction and impact by material carried in air, water, or ice.
