Question

Explain what causes a geyser to erupt.

Answer 1

Geysers erupt because surface water seeps down under the surface to magma heated rock and is forced back up by way of convection. Hope this helps.

Answer 2

Answer: Sample response:

Geysers form in areas where groundwater is heated by contact with hot rock. The boiling hot water can’t expand and change to steam. Instead, it moves upward through cracks in the rock. As the water nears the surface, the pressure on the water is suddenly released and it changes to steam. The geyser erupts as a fountain of steam and bubbles jets high into the air.
