To match the columns correctly, we need to understand the terms listed in both Column A and Column B, as they pertain to geographical formations and features.
Column A:
Delta - A delta is typically a fan-shaped landform located at the mouth of a river, where it deposits sediment as it flows into a slower-moving or standing body of water, like a sea or lake.
Anticline - An anticline is a type of fold that is arch-like and has its oldest beds at its core, characterized by an upward convex shape.
Syncline - In contrast, a syncline is a fold with a downward curvature, creating a trough-like structure where the youngest layers are at the core.
Bed - In geology, a bed refers to a layer of sediment or sedimentary rock, which is often found as part of formations in riverbeds or sediment deposition areas.
Banks - This refers to the sides of a river or stream channel, often defining where water flows.
Column B:
(a) Downfolds - Associated with synclines as they represent troughs or downfolds in layering.
(b) Upfolds - Associated with anticlines, which are upward folds.
(c) Fan-shaped built-up areas - Represents deltas, given their fan-like appearance where rivers meet larger water bodies.
(d) Side of the channel - This matches with banks, as they are indeed the sides of a water channel.
(e) Bottom of the channel - This aligns with bed, indicating the bottom layer of a river or stream channel.
Using this information, the correct matches are:
Delta - (c) Fan-shaped built-up areas
Anticline - (b) Upfolds
Syncline - (a) Downfolds
Bed - (e) Bottom of the channel
Banks - (d) Side of the channel
Each term relates to significant geographical processes or structures, which are key components in understanding the physical landscape and its formation.
