The correct answer is A. Unlike surface water, groundwater is also responding to pressure in addition to gravity.
Explanation:
A groundwater aquifer is a saturated underground earth formation that may consist of permeable or unstructured rocks (gravel, sand or lime). The water is stored and circulated through these materials. This water can be extracted using wells, mines and other catchment systems.
When the permeable rock where water accumulates is located between two impermeable layers, it is called a confined aquifer. In this case, the water is under a higher pressure than the atmospheric one.
Answer: The Ring of Fire is an area of tectonic activity. It surrounds the Pacific Ocean and runs along the west coast of Latin America. Large numbers of earthquakes and volcanic eruptions occur in this zone. In 2010, a major earthquake struck the coast of Chile. The earthquake resulted in massive damage to infrastructure
