Which of the following statements is not correct?

The statement "Rocks that are changed by great heat and pressure are called sedimentary rocks" is not correct. Sedimentary rocks are actually formed through the accumulation and solidification of sediment, while rocks that are changed by great heat and pressure are called metamorphic rocks. Metamorphic rocks are formed from other rocks that undergo extreme heat and pressure, resulting in the recrystallization of minerals and the development of new textures and structures. Examples of metamorphic rocks include marble and gneiss. Igneous rocks are formed through the solidification of molten magma, and examples include basalt and granite. Volcanic rocks are a type of igneous rock that are formed through the extrusion of magma onto the earth's surface. Igneous rocks generally do not contain fossils, as the intense heat and pressure involved in their formation destroys any organic matter.
