Question

What are the physical characteristics of a river? need answers PLZ!?

Answer 1

There are many:

Meander - A meander in general is a bend in a river.

Waterfall - When a River, flows over hard rock which has softer rock underneath. The river erodes the softer rock. eventually the harder rocket cannot be supported to breaks. The waterfall reatreats back to form a gorge.

OxBow lake - An oxbow lake is a U-shaped lake water body formed when a wide meander from the river is cut off to create a lake.

Current - The current ina  river runs fastest around the outside bend so in a meander, the inside bends erodes more. The outside bend is therefore a lace of deposition where the current is slowest.

Processes of Erosion -

Attrition: Bolders collide and break up smaller rock.

Hydraulic Action: Force of river dislodges rock from River bank and bed.

Corrasion: Particles in suspension rub against river banks.

Solution (Corrosion): When minerals are dissolved in water.

Processes of Transportation -

Traction (rolling): Boulders roll on the floor.

Saltation: Sand Sized particles bounce along the floor.

Suspension: Silt clay carried in water.

Solution: Minerals dissolved in water.
