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:
B) The warm, moist Pacific air rises and cools, releasing precipitation as it moves up the windward side of the range, and this cool, now dry air mass heats up as it descends on the leeward side of the range
Explanation:
The air masses that have formed over the Pacific and move toward the western coast of the United States are warm and moist ones. As they reach the coastline they continue into the mainland, but only to come upon a natural barrier, a north-south mountain range. The warm and moist air starts to move up and starts to cool off, and as it does, condensation occurs, thus the windward side of the mountain range gets a lot of precipitation. The cool, but now dry air continuous its movement across the mountain range, and moves down its leeward side. As it moves down on the leeward side it heats up again, so it becomes a warm and dry air mass. This makes the leeward side very dry, so it is no wonder that it is dominated by desert and semi-desert.
