While lava and magma are the basis of igneous rocks, sediments are the building blocks of sedimentary rocks. Sediments are small bits of rocks caused by the erosion, or breaking down, of other rocks. Water and wind cause this erosion, which is sometimes called weathering. Sediments can be incredibly small or as …

Rocks. There are three main categories of rocks, which are defined by how the rocks are formed. Sedimentary Rocks. Sedimentary rock is often found in layers. One way to tell if a rock sample is sedimentary is to see if it is made from grains. Some samples of sedimentary rocks include limestone, sandstone, coal and shale.

Sandstones comprise about 20–25% of all sedimentary rocks.. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface.

Floor 1. Metamorphic rocks form when sedimentary, igneous, or pre-existing metamorphic rocks are changed by heat, pressure, and chemically reactive waters. These rocks are identified by their minerals and texture. During metamorphism, new minerals grow, with different sizes, shapes, and orientations than those of the original minerals.
