Section C: Physical landscapes in the UK

Question

A. By the deposition of sediment at the river mouth.
B. By the erosion of the river bank during flooding.
C. By the cutting off of a meander from the main river.
D. By the accumulation of glacial meltwater.

Answer

The correct answer is By the cutting off of a meander from the main river..

Explanation

The correct option is By the cutting off of a meander from the main river.. By the cutting off of a meander from the main river. is correct because it directly matches the approved learning objective to explain the characteristics and formation of erosion and deposition landforms including meanders and ox-bow lakes. This belongs to River landscapes in the UK (optional route) within Section C: Physical landscapes in the UK, so the answer must stay focused on the geographical process, evidence, place, or impact named by the curriculum. The other options are weaker because they move away from River landscapes in the UK (optional route), reverse the geographical relationship, or make a broader claim than the objective supports.

Common mistake

Confusing Meanders and Oxbow Lakes

Students often confuse the formation processes of meanders and ox-bow lakes, thinking they are the same feature.

Meanders are curves in a river formed by erosion and deposition, while ox-bow lakes are formed when a meander is cut off from the river, creating a crescent-shaped lake.
