What is 'hydraulic action' in the context of river processes?

• When rocks carried by water wear the land away

• When bubbles of air are forced into cracks, shattering the rock

• When water dissolves minerals from rocks

• When rocks and pebbles wear down by hitting each other

What does 'abrasion' refer to in river erosion?

• The dissolving of minerals from rocks by water

• The deposition of materials on the inside bend of a river

• The process of rocks wearing down the land as they are carried by water

• The breaking of rocks into smaller pieces due to collision

What is 'solution' in the context of river erosion?

• The mechanical breakdown of rocks into smaller pieces

• The chemical process where water dissolves minerals from rocks

• The action of water carrying rocks to erode the river bed

• The deposition of sediments on river bends

What describes the term 'attrition' in river processes?

• The smoothing of pebbles by water action

• The movement of eroded materials from the outside to the inside bend

• The formation of river cliffs by fast-moving water

• The wearing down of rocks as they collide and break into smaller pieces

What is the effect of water traveling fastest at the outside bend of a river?

• It causes the water to slow down significantly

• It erodes the river cliff, shaping the river bend

• It erodes the river bed, deepening it

• It deposits more sediments, forming a river beach
