This is where the system connects to the geyser’s heat source. Each geyser’s plumbing system is different. Some consist of a single, long vertical shaft while others connect to large areas of water beneath the Earth’s surface (How Geysers Form and Erupt). Certain types of soil are also much better for the plumbing formation (How Geysers Form and Erupt). These soils usually contain a high concentration of a volcanic rock that contains minerals that seal the lining of the plumbing system (How Geysers Form and Erupt). The mineral lining is very important to the geyser’s formation due to geyser’s operating under a large amount of pressure (How Geysers Form and Erupt). The plumbing system must be able to hold this pressure for the geyser to function (How Geysers Form and …show more content…
The eruption process begins as the water moves to the geyser’s plumbing through openings in the ground (Atteberry 2009). Due to the plumbing system being miles below, the water below the geyser’s plumbing is under a large amount of pressure from the water above it (Atteberry 2009). We can think of the system as a large pressure cooker or even boiling water. When water reaches the boiling point, the water starts to move and bubbles begin to rise to the surface. The more pressure that is exerted on the water, the more the water needs to move and the more energy overcomes the pressure which pushes bubbles to the surface (Atteberry
