Write a hypothesis about the effect of mineral composition, acidity, temperature, and surface area on the rate of weathering using the “If…then…because…” format. Be sure to answer the lab question, “What factors influence the rate of weathering?”

rising temperatures because when water vapor in the air is cooled, it condenses. it turns back into a liquid and attaches to dust particles in the air. these very small water droplets group together to form clouds

these muscles maintain the blood pressure in the vessels. the smooth muscles are innervated by nerves of the autonomic nervous system. when the muscles contract, they cause vasoconstriction of the vessels and increase blood pressure. when the muscles relax, they enable vasodilation of the   blood vessels hence reduce blood pressure.
