Valmonte Image from : http://www.esc.cam.ac.uk/images/research/petrology/lava_flow Where do rocks melt? -Layers of the Earth diagram The rocks start to melt at the upper mantle (200km deep from the surface of the earth Takes 600-1300 degrees to melt a rock (To turn it into a molten rock called “Magma”) http://www.wired.com/2012/12/why-do-rocks-melt-volcano/ What happens when rocks melt? Igneous Processes • Diagram of the Rock cycle What is magma? • Magma is a semi-molten rock *Temp. of magma is around 800 C to 1100°C • Found under the surface of the Earth • Have high silica content http://cx.aos.ask.com/question/aq/700px-394px/what-is-molten-rock_e9b070f7-d7ef-45b5-abac-240b4c3fbf29.jpg What is Magma made of?
