Question

Which statements accurately describe groundwater? Check all that apply.

Groundwater is water found below Earth’s surface.
Groundwater erosion creates oxbow lakes.
Groundwater erosion leads to the creation of caves.
Groundwater flows across the ground.
Groundwater can cause chemical weathering.

Answer 1

Correct answers:
- Groundwater is water found below Earth’s surface. (True)
- Groundwater erosion leads to the creation of caves. (True)
- Groundwater can cause chemical weathering. (True)

Why: groundwater moves through pore spaces and fractures underground and dissolves soluble rock (especially limestone), producing caves and karst features and causing chemical weathering.

Incorrect:
- Groundwater erosion creates oxbow lakes. (False) — Oxbow lakes form from river meanders and surface erosion/deposition.
- Groundwater flows across the ground. (False) — That describes surface water; groundwater flows below the surface.
