This list details the ten most toxic and potentially deadly minerals that crystalize in the Earth s rocks presenting a dangerously deceptive array of stony beauty. The three main types or classes of rock are sedimentary metamorphic and igneous and the differences among them have to do with how they are formed. Igneous rock is formed through the cooling and solidification of magma or lava. The crust varies in thickness and density with oceanic crust consisting of a thin around 5 km layer of dense rock and continental crust consisting of less dense lighter colored rock ranging Basalts are still predominant but other compositions are part of the series and the types of rocks produced are variable from one island to the next. River rocks are most often found on beaches and in stream beds and can come in a range of sizes colors and textures. We have organized information in a tabular form where you will find the origin discoverer of all the types of rocks list of their colors and textures and many unique and intriguing facts about Volcanic Rocks. We often find metamorphic rocks in mountain ranges where high pressures squeezed the rocks together and they piled up to form ranges such as the Himalayas Alps and the Rocky Mountains. So it s rare to find sedimentary rocks at the ocean bottom. Some of the common types are listed below.
