Description
This great selection of rocks, minerals and fossils includes a fossil collection up to 70 million years old (9 fossils), an igneous rock collections which have been produced by hot volcanic magna action (12 rocks), a mineral collection (12 minerals) and a sedimentary rock collection, formed by layers of deposited matter (12 rocks). Each set comes with an identification chart, self-adhesive labels, handy storage tray and information-packed guide. Igneous rocks are one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava. There are two types of igneous rocks: extrusive and intrusive rocks, depending on the way they are formed. Minerals occur naturally, stable at room temperature, and is represented by a chemical formula. A mineral is usually not resulting from activities from living organisms.Fossilsare the preserved remains or traces of animals, plants, and other organisms from the remote past.Sedimentary rocks are formed by the deposition and subsequent cementation of that material at the Earth?s surface and within bodies of water
