a meander is a

• narrow bridge over a river
• sharp turn in a river
• winding curve or bend in a river
• straight line in a river

what is plucking in glacier erosion

• Plucking is the process where glaciers deposit rocks instead of pulling them from the bedrock.
• Plucking is the process where meltwater at the base of a glacier freezes onto rocks, and as the glacier moves, it plucks or pulls these rocks from the bedrock, carrying them along and causing erosion.

what is a delta

• A delta is a river in Egypt.
• A delta is a type of triangle.
• deposited sediment that builds up a landform as a river flows into an ocean or lake

what is mechanical weathering

• Mechanical weathering is the process of rocks changing color due to weather exposure.
• Mechanical weathering involves the chemical alteration of rocks.
• Mechanical weathering is caused by volcanic activity.
• Mechanical weathering is the breakdown of rocks into smaller pieces without changing their chemical composition.

what are the agents of the mechanical weathering

• freezing and thawing, release of pressure, plant growth, actions of animals, and abrasion

• water,oxygen,carbon dioxide, and living organisims
