The Old Faithful geyser found in Yellowstone Park is an example of _____. a feature resulting from earthquake activity a feature
Monica [59]

The given blank can be filled with a feature resulting from hot volcanic rock.  

The geysers refer to the rare characteristics on Earth, only about 1000 of them prevail, and more than half of those are situated in Yellowstone. For a geyser to develop, there must be a source of volcanic heat, enough groundwater, and a geologic plumbing system via which the heated water can escape.  

The absconding of water takes place when the groundwater is heated by the hot volcanic rocks. The intensifying steam bubbles push the water above via the fissures in the rock until they overflow from the geyser.  

With the absconding of the top layers of the water, the pressure on the hotter waters below diminishes, leading to a violent chain reaction of explosions, which expand the volume of the rising boiling water by up to 1500 times or more.

Cochlear implants functions just like the hair cells and capture sound and transmit it via the vestibulocochlear nerve or the cranial nerve VIII and then to the temporal lobe in the auditory cortex.
