Make two shapes to represent the two stages before rock is formed: magma and sediment. This is known as the rock cycle. Sedimentary rocks are made up of different types of particles, or sediments, such as sand, tiny particles of silt, or small pebbles.
A rock is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. It is categorized by the minerals included, its chemical composition and the way in which it is formed. Rocks are usually grouped into three main groups: igneous rocks , sedimentary rocks and metamorphic rocks. Rocks form the Earth's outer solid layer, the crust , and most of its interior, except for the liquid outer core and pockets of magma in the asthenosphere.

Rock , in geology , naturally occurring and coherent aggregate of one or more minerals. Such aggregates constitute the basic unit of which the solid Earth is composed and typically form recognizable and mappable volumes. Rocks are commonly divided into three major classes according to the processes that resulted in their formation. These classes are 1 igneous rocks, which have solidified from molten material called magma; 2 sedimentary rocks, those consisting of fragments derived from preexisting rocks or of materials precipitated from solutions; and 3 metamorphic rocks, which have been derived from either igneous or sedimentary rocks under conditions that caused changes in mineralogical composition , texture, and internal structure. These three classes, in turn, are subdivided into numerous groups and types on the basis of various factors, the most important of which are chemical, mineralogical, and textural attributes. Igneous rocks are those that solidify from magma , a molten mixture of rock-forming minerals and usually volatiles such as gases and steam.
GSA Bulletin ;; 84 11 : — The properties of four igneous rocks a tholeiitic and an alkali-olivine basalt, an andesite, and a rhyolite and a synthetic lunar sample have been determined at atmospheric pressure over a range of temperatures including their melting interval. Viscosity, density, electrical and thermal conductivity, ultrasonic wave velocities, surface tension, and vesiculation rates were measured directly; these data have been used to calculate values for thermal expansion, compressibility, ultrasonic wave attenuation, and activation-energy coefficients.
