Throughout the last step, some of the metamorphic rocks melt as they get close to molten magma. Test your understanding with practice problems and step-by-step solutions. What are sills and where they can be found? However, in a case where magma does not have enough silica relative to the magnesium oxide to produce the pyroxene, the magma will compensate by making a magnesium-olivine (forsterite; Mg2SiO4), along with the pyroxene, since the olivine requires only one-half as much silica for every mole of magnesium oxide.

Within Earths deep crust the temperatures and pressures are much higher than at its surface; consequently, the hot magma cools slowly and crystallizes completely, leaving no trace of the liquid magma. Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. Articles from Britannica Encyclopedias for elementary and high school students. The practice worksheet will test students understanding of the traits of specific rock types. Layers of rock wear off as well during a process scientists call exfoliation. You could also plan a Rock Week during which you teach about all the types of rocks, including this lesson and the one on the rock cycle. Grades PreK - 2.
