Some facts about igneous rocks include that they are glassy in nature, that pumice igneous rock is the lightest type of rock on Earth, and that the moon is made of igneous rocks Igneous rocks come from molten magma and have two main versions: basalt and pumice.

Sedimentary rocks are made of particles of sediments such as sand and clay, or the skeletons and shells of sea creatur When layers of loose sediment are buried and pressed down under more layers, the particles slowly cement together and lithify (form rock).

Children might also learn about the rock cycle (as soon as igneous rocks are exposed to air they begin to be eroded and form sediments; the sediments will then be pressed together to form sedimentary rock, which might then become metamorphic rock and finally melt beneath the Earth's crust and erupt as lava, before becoming igneous rock once again).

How Are Conglomerate Rocks Formed? Conglomerate rocks are formed by the sedimentary rock process, which is: erosion, transport, deposition and cementation Two characteristic properties of conglomerate rock are that the sedimentary particles, or clasts, are greater than 2 millimeters in size, and the clasts are rounded in appearance.

Sedimentary rocks are made when sand, mud and pebbles get laid down in layers Over time, these layers are squashed under more and more layers Eventually, the layers are lithified - turned to rock Sedimentary rocks can be formed in deserts, lakes, rivers and seas More information.

Sedimentary rocks are the most common rock types which are freely exposed on the earth’s surface They are formed from other rock materials since they are made up from the buildup of weathered and eroded pre-existing rocks The weathering, erosion and the eventual compaction of igneous, metamorphic or formerly structured sedimentary rocks among other biological sedimentations leads.
