Like most Earth materials, rocks are created and destroyed in cycles. The rock cycle is a model that describes the formation, breakdown, and reformation of a rock as a result of sedimentary, igneous, and metamorphic processes. All rocks are made up of minerals. A mineral is defined as a naturally occurring, crystalline solid of definite chemical composition and a characteristic crystal structure. A rock is any naturally formed, nonliving, firm, and coherent aggregate mass of solid matter that constitutes part of a planet.
The examples of positive feedback loops are as follows:
- contractions during the process of giving birth
- Blood clotting
<h3>WHAT IS POSITIVE FEEDBACK LOOP:</h3>
- Positive feedback loop is that in which a change in a given direction causes additional change in that same direction.
- The contractions during the process of giving birth is an example of positive feedback loop because the contractions further stretch the walls and continues until birthing occurs.
- Also, the clotting of blood causes the stoppage of blood flow.
Therefore, the examples of positive feedback loops are as follows:
- contractions during the process of giving birth
- Blood clotting

Cellular respiration takes in food and uses it to create ATP, a chemical which the cell uses for energy. Usually, this process uses oxygen, and is called aerobic respiration. It has four stages known as glycolysis, Link reaction, the Krebs cycle, and the electron transport chain. yup
