GEOLOGY

Detailed explanation-1: -The resultant boiling of the pressurized water results in the geyser effect of hot water and steam spraying out of the geyser’s surface vent (a hydrothermal explosion).

Detailed explanation-2: -Geysers occur in locations where there’s a coincidence of certain unusual conditions. These include the presence of hot magma beneath the earth’s surface. An abundant supply of groundwater and the presence of vents or fissures through which the water and steam erupt to the surface.

Detailed explanation-3: -First, a brief overview on how geysers form. It begins with groundwater flowing through rhyolitic rocks. These rhyolitic rocks mainly consist of silica (SiO2) and are heated by a deep magma body beneath the Yellowstone Caldera.

Detailed explanation-4: -A geyser is a rare kind of hot spring that is under pressure and erupts, sending jets of water and steam into the air.
