GEOLOGY

Detailed explanation-1: -Springs are formed where the water table naturally meets the land surface, causing groundwater to flow from the surface and eventually into a stream, river, or lake. The water table level can vary in different areas and even within the same area.

Detailed explanation-2: -Figure 12.9 and 12.12: A spring is a natural flow of water that occurs when the groundwater table intersects the land surface. The water emerges at the ground surface.

Detailed explanation-3: -A spring is a natural flow of groundwater to Earth’s surface in places where the ground surface dips below the water table. Wells and springs are classified into two groups-ordinary and artesian.

Detailed explanation-4: -Depression springs are formed in unconfined aquifers when the topography intersects the water table, usually due to the surface stream incision.

Detailed explanation-5: -Springs occur when water pressure causes a natural flow of groundwater onto the earth’s surface. As rainwater enters or “recharges” the aquifer, pressure is placed on the water already present.
