Question
Work of groundwater and landforms
✓
Answer
The rainwater seeps below the earth’s surface through porous rocks or the cracks in the rocks.
This water accumulates at the non-porous layer of the rock. This accumulated water is called groundwater.
The soluble minerals in the water get dissolved and flow with the groundwater. This is the erosional work of the groundwater.
When the groundwater evaporates or the volume of soluble minerals is more than the solubility of the groundwater, the deposition of dissolved materials starts.
Landforms like sinkholes, limestone caves, stalactites and stalagmites are formed.
Thus, the groundwater carries out the erosion, transportation and depositional work.
