👉 The term "cratons" refers to a group of solidified rock that is separated from the surrounding environment by layers of sedimentary rocks. These layers are typically composed of sand, silt, and gravel, and they can be found in different geological formations such as metamorphic rocks or igneous rocks. Cratons are commonly found in the Earth's crust, particularly in areas where there has been a volcanic eruption, such as on the surface of the Moon or Mars.
