'X' is a vent in Earths surface that periodically ejects a column of hot water and steam. The formation of it is a rare phenomenon because it is due to particular hydrogeological conditions which exist at few places on Earth. Taupo volcanic zone in New Zealand is one of its examples. Identify 'X'.

Introduction:
The rare phenomenon described in the question refers to a vent in Earth's surface that periodically ejects a column of hot water and steam. This feature is known as a geyser.

Definition of a Geyser:
A geyser is a hydrothermal feature characterized by intermittent eruptions of hot water and steam. It occurs when water beneath the surface is heated by geothermal energy, causing it to rise and erupt through a vent.

Formation of a Geyser:
The formation of a geyser requires specific hydrogeological conditions to exist. These conditions are found at only a few places on Earth. The following factors contribute to the formation of a geyser:

1. Heat Source: A heat source, typically a magma chamber or a geothermal gradient, is required to heat the underground water. This heat source provides the energy necessary for geyser eruptions.

2. Plumbing System: A geyser needs a complex plumbing system consisting of a reservoir to hold the water, a narrow conduit to channel the water towards the surface, and a vent through which the water erupts.

3. Confining Layer: The water reservoir must be located beneath a confining layer, such as impermeable rocks or clay, which prevents the water from easily escaping to the surface. This buildup of pressure within the reservoir contributes to the explosive nature of geyser eruptions.

4. Superheating: As water is heated underground, it can become superheated, meaning it remains in a liquid state despite being at a temperature above its boiling point. This superheated water is highly pressurized and can lead to explosive eruptions when it reaches the surface.

5. Recharge: A geyser needs a continuous supply of water to sustain its eruptions. This water typically comes from rainfall or snowmelt that percolates through the ground and replenishes the underground reservoir.

Example of a Geyser:
The Taupo volcanic zone in New Zealand is one of the examples of a geyser. It is home to the famous Waimangu Geyser, which was active from 1901 to 1904. The hydrogeological conditions in this region, including a heat source from volcanic activity, a plumbing system, and a confining layer, allow for the formation of geysers.

Conclusion:
Geysers are a rare phenomenon due to the specific hydrogeological conditions required for their formation. They occur at only a few places on Earth, with the Taupo volcanic zone in New Zealand being an example. Understanding the factors contributing to geyser formation helps explain why they are not commonly found and adds to our knowledge of Earth's dynamic processes.

A geyser is a vent in Earth's surface that periodically ejects a column of hot water and steam. They are a quite rare phenomenon on Earth due to the precise conditions that are required for them to form. They are mainly clustered near active volcanic areas. 
The Taupo Volcanic Zone in New Zealand is 350 km long and 50 km wide and contains volcanoes, hot springs and geysers. The largest geyser ever known, the Waimangu Geyser, sat in the Taupo Volcanic Zone.
