How Geysers Start
Our Earth consists of many regions where magma, or hot lava. lies beneath the surface. This magma works like a burner on a stove, hooting any water in the ground until it grows very hot Mast water beneath Earth's surface comes from rain and melting snow. This water passes through cracks in the earth and collects underground. If this water lies close enough to hot magma, it heats and begins to boll:

Solution

failed
failed

The answer is the fourth one: to explain how geysers are formed below Earth's surface and how they erupt.

Explanation for each option:

  1. To introduce the idea that even the most reliable of geysers can be inconsistent: This option is incorrect because the text does not discuss the inconsistency of geysers, particularly Old Faithful. The focus is on the formation and eruption process of geysers in general.

  2. To illustrate the importance of geysers to our natural world and our environment's health: This option is incorrect because the text does not emphasize the environmental importance or health benefits of geysers. It is more focused on the geological process.

  3. To provide information about geysers and how we can preserve them worldwide: This option is incorrect because the text does not discuss preservation strategies for geysers. It is centered on explaining the natural process of geyser formation and eruption.

  4. To explain how geysers are formed below Earth's surface and how they erupt: This option is correct because the text provides a detailed explanation of the process by which water is heated by magma, leading to the formation and eruption of geysers.

In summary, the section on Yellowstone's Old Faithful is included to explain the geological process of geyser formation and eruption.
