In Science, we are looking at the three different types of rocks and how they are formed. We learnt that igneous rocks are formed when magma cools into rock. Sedimentary rocks are formed under water and under lots of pressure. Metamorphic rocks are rocks that were once igneous or sedimentary rocks come under intense heat or pressure and they change into a new type of rock. Last week we looked at different rocks and decided whether they were igneous, sedimentary or metamorphic rock!
