Metamorphic rocks.<\/p>\n<p>Gneiss is a type of metamorphic rock that is formed when existing rocks are subjected to high heat and pressure. The original rock can be any type, but it is most commonly igneous or sedimentary rock. When the rock is subjected to these conditions, the minerals in the rock recrystallize and form new minerals. The new minerals are often aligned in bands or layers, which give gneiss its characteristic appearance.<\/p>\n<p>Igneous rocks are formed when magma or lava cools and solidifies. Sedimentary rocks are formed when pieces of other rocks or minerals are deposited and compacted over time. Sedimentary metamorphic rocks are formed when sedimentary rocks are subjected to high heat and pressure.<\/p>\n<p>Gneiss is a strong and durable rock that is often used in construction. It is also a popular choice for landscaping and garden features.<\/p>\n<p>Here is a diagram that shows the different types of rocks and how they are formed:<\/p>\n<p>The diagram shows that igneous rocks are formed when magma or lava cools and solidifies.
