A geyser is a type of artesian well.

during colder climates.
Changes that occur in one part of the climate system are isolated and will have no part
on the remainder of the system.

Water expands when it freezes.
The water table undulates with the ground surface. It is low where the ground surface is
high and high where the ground surface is low.

objective testing and analysis.
Because massive submarine structures such as seamounts and ridges exert stronger than
average gravitational attraction, they produce depressed areas on the ocean's surface.

or ice.
