The cervix is the neck of the uterus, leading to the vagina. Itâs not a smooth pipe, but a passage filled with crevices. In these nooks and crannies, CM is produced and released. Hormonal changes over the course of a womanâs menstrual cycle affect the amount and the consistency of CM.

Scientists generally classify rocks by how they were made or formed. There are three major types of rocks: Metamorphic, Igneous, and Sedimentary. Metamorphic Rocks - Metamorphic rocks are formed by great heat and pressure. They are generally found inside the Earth's crust where there is enough heat and pressure to form the rocks. Metamorphic rocks are often made from other types of rock. For example, shale, a sedimentary rock, can be changed, or metamorphosed, into a metamorphic rock such as slate or gneiss. Other examples of metamorphic rocks include marble, anthracite, soapstone, and schist. Igneous Rocks - Igneous rocks are formed by volcanoes.
