Answer 1

The answer is D It is a geyser that formed due to water heated by magma erupting at Earth's surface.

Answer 2

The correct answer is D.

Old Faithful is located in the Yellowstone National Park in the state of Wyoming. It is a cone geyser, named this way because of its frequent and somehow predictable eruptions which number more than a million.

The geyser was discovered in 1870 by the Washburn expedition. The geyser erupts a column of steam and super hot water. The water escapes when the ground water is heated to the boiling point by the hot volcanic rocks. The super heated water escapes and bursts into the sky to form a geyser's fountain.
