Rock Cycle A cool trip around the rock cycle

What is a rock? A rock is a mixture of such minerals, rock fragments, volcanic glass, organic matter, or other natural materials. Most rock used for building stone contains one or more common minerals, called rock-forming minerals, such as quartz, feldspar, mica, or calcite When you look closely, the sparkles you see are individual crystals of minerals.

What is the difference between a rock & a mineral? Minerals are solid, naturally occurring, inorganic, have a fixed composition and are made of one or more elements. Rocks are made of one or more minerals.

Made of elements Solid Can be made of lava/ magma Have crystals Can be formed from solutions Must be inorganic Made only of compounds Elements must be chemically bonded Naturally occurring Can be made from organic materials Mixtures made of minerals Can be man made

Rock Types There are three types of rocks Igneous Sedimentary Metamorphic

What is the rock cycle? To show how rocks slowly change through time, scientists have created a model called the rock cycle. It illustrates the processes that create and change rocks.

Rock Cycle Continued The rock cycle shows the three types of rock— igneous, metamorphic, and sedimentary—and the processes that form them.

What is the law of conservation of matter? Law of conservation of matter states that matter cannot be created or destroyed. The changes that take place in the rock cycle never destroy or create matter. The elements are just redistributed in other forms.
