Answer:
A large or small depression, or a low spot, in the land surface is called Basin.
Answer and Explanation:
A hydro-thermal vent can be defined as a crevice on the floor of the sea from which water heated by geothermal energy erupts or issues. These vents are common near places that are volcanically active, areas where the movement of the tectonic plates is away from the spreading centers, hotspots, ocean basins,etc.
Marine researchers know the sites for hydro-thermal vents by computing the exact location of the place of active volcanic sites which provides the movement to the the tectonic plates which in turn produces gas and undergo some thermal processes making it easily detectable for the location of thermal vent sites.
They can be sure of finding a vent by calculating the activeness of active volcanic sites in the hydrological places.

Answer:
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.
The greenhouse effect is related to the increase in the average surface temperature which is considered "global warming". Global warming is the result of an increase in gases like methane, carbon dioxide, and other factors that lead to a rise in the planet's temperature.
