What geological condition primarily leads to the formation of springs?
What geological condition primarily leads to the formation of springs?
- Intense seismic activity causing underground fissures.
- The presence of non-porous rock layers preventing water infiltration.
- The water table intersecting the ground surface. (correct)
- High levels of soil erosion exposing underground aquifers.
A key characteristic that differentiates hot springs from regular springs is:
A key characteristic that differentiates hot springs from regular springs is:
- Their water containing higher concentrations of dissolved minerals.
- Their association with volcanic activity, leading to increased water temperature. (correct)
- Their flow rate being significantly higher than regular springs.
- Their location in high-altitude regions.

What is the defining feature of a geyser?
- The collection of stagnant water in underground caverns.
- The periodic and forceful eruption of water and steam. (correct)
- A continuous, steady flow of groundwater to the surface.
- A slow seepage of mineral-rich water from porous rocks.

Study Notes
- Springs are small streams found in hill slopes and courtyards during rainy seasons.
- Water flows out along the surface where the water table touches the ground, creating a spring.
- Some springs are characterized by hot water, known as hot springs.
Geysers
- Geysers are a phenomenon of severe ejection of water from within the earth at regular intervals.
- An example is The Old Faithful geyser of the Yellow Stone National Park in the U.S.A.
Horizontal Wells of the Kasaragod Region
- In the Kasaragod and south Canara districts, people collect drinking water by constructing horizontal wells.
- These wells are dug horizontally along the foot of hills.
- Water flows out from narrow 'Surangams' (gaps cut on hill sides), which are barely wide enough to enter.
- It is believed that this technique arrived through trade relations with the Arab world.
