AS OCR Geog: River Processes

A crossword to gain familiarity with key terms of processes in rivers/river basins.

?
9 letters. Type of mechanical weathering. Water expands by 9% when it freezes to form ice.
freezethaw
1 of 19
9 letters. Type of chemical weathering. Oxygen reacts with minerals like iron, causing rocks to rust.
oxidation
2 of 19
10 letters. Type of chemical weathering. Decomposition of a chemical compound by reaction with water.
hydrolysis
3 of 19
6 letters. This is a factor controlling type/rate of weathering. Can be defined as the direction of which the sun or rain comes from.
aspect
4 of 19
10 letters. This is a factor controlling type/rate of weathering. It can also cause biological weathering (root growth).
vegetation
5 of 19
7 letters. This is a factor controlling type/rate of weathering. It can be defined as weather conditions prevailing in an area in general.
climate
6 of 19
12 letters. Movement of material under the force of gravity.
massmovement
7 of 19
7 letters. Could result from wind, ice, sea, human activity or the river itself. The rate of this process is increased during storms and floods. Sediment is typically added to the river from this process.
erosion
8 of 19
9 letters. Carries the load. Rate is determined by energy available and the weight of load.
transport
9 of 19
8 letters. Material dissolved in water.
solution
10 of 19
10 letters. Material held in water.
suspension
11 of 19
9 letters. Material bouncing along river bed.
saltation
12 of 19
8 letters. Material dragged along river bed.
traction
13 of 19
8 letters. Load is used to wear away banks/bed.
abrasion
14 of 19
9 letters. Sheer force and weight of falling water erodes rocks.
hydraulic
15 of 19
10 letters. Load collides with each other and grinds into smaller fragments.
attrition
16 of 19
8 letters. The erosion of chemical ions causes rocks to dissolve.
solution
17 of 19
10 letters. Type of flow in meanders...corkscrew-like motion.
helicoidal
18 of 19
11 letters. Process by which surface sediment is incorporated into a fluid flow (air, water, ice).
entrainment
