Section 1. Volcanic Eruptions. Volcanoes – areas of Earth’s surface through which magma and volcanic gases pass. In seconds a volcanic eruption can turn an entire mountain into a cloud of ash and rock. Target #16- I can summarize the conditions needed for magma to form. Despite the high temperature in the mantle, most of the layer remains solid due to extreme pressure. Magma: . liquid rock produced under Earth’s surface. Youtube. :.

Viscosity is the property of matter that allows it to hold it’s shape (or the property that allows it to resists flowing).. Low Viscosity means that it is more runny/thin (like water).. Section 3: .

A group of rocks that share some chemical, and sometimes mineralogical, characteristics. They share patterns on chemical variation diagrams which suggests a genetic relationship – beyond the scope of this course. Magma is a mixture of molten rock, volatiles and solids that is found beneath the surface of the Earth.. In some instances, it solidifies within the crust to form . plutonic rocks. . In others, it erupts onto the Earth’s surface to form .
