• Lithosphere
In Yellowstone, the interplay between volcanic, hydrothermal, and glacial processes, and the distribution of flora and fauna are intricate. The topography of the land from southern Idaho northeast to Yellowstone probably results from millions of years of hot spot influence. [1] Yellowstone Plateau itself is a result of uplift due to hot spot volcanism.
The volcanic rhyolites and tuffs of the Yellowstone Caldera are rich in quartz and potassium feldspar, which form nutrient-poor soils. Thus, areas of the park underlain by rhyolites and tuffs generally are characterized by extensive stands of lodgepole pine, which are drought tolerant and have shallow roots that take advantage of the nutrients in the soil.
In contrast, andesitic volcanic rocks that underlie the Absaroka Mountains are rich in calcium, magnesium, and iron. These minerals weather into soils that can store more water and provide better nutrients than rhyolitic soils. These soils support more vegetation. [1]
Yellowstone is the largest volcano in the world lies underground. Magma or heat under the ground as a result of many things. Such as a lift of Soil, separated from each other and earthquakes. The volcano lies underground influence that made the mud pond, hot spring, which has more than 10,000. Volcanic soil is high in nutrients.
