Question
State three conditions that favour the formation of an artesian basin.
Answer
What is an Artesian Basin
An artesian basin, also known as an artesian aquifer or confined aquifer, is a geological formation that consists of layers of permeable rock or sediment (such as sandstone, limestone, or gravel) sandwiched between impermeable layers of rock or clay. This geological arrangement allows groundwater to be stored and flow under pressure, creating artesian wells and springs.Conditions that Favour the Formation of an Artesian Basin
- The aquifer must be sandwiched between impermeable rocks so that it can retain water- The aquifer must outcrop in a region which is a source of water
- The mouth of the well must be lower than the intake area to allow water to be forced out by pressure
- The aquifer must dip from a region of water intake and the rock layers must form a broad basin.
