The dots on the map represent deep, underground hydrothermal resources in the united states. why do more hydrothermal resources exist in the western regions of the united states?
a) geological processes contributed to the formation of vents in that region.
b)western states experience more wildfires than eastern states.
c)the western region has far fewer trees, leading to higher wind production.
d)lack of groundwater and extended drought has reduced the number of vents.

The correct answer is - a) Geological processes contribute to the formation of vents in that region.

The western part of the United States is geologically much more active than the other parts of the country. This is due to the geological activity in the region which is caused by the subduction of the heavier oceanic Pacific tectonic plate under the lighter North American tectonic plate. Because of this, the pressure, temperatures, magma, gases, form the mantle are able to come to the surface, and one of the results is the hydrothermal activity.
