A quarry is a type of open-pit mine from which rock or minerals are extracted. Quarries are generally used for extracting construction materials, such as dimension stone. Quarries are usually shallower than other types of open-pit mines. People in some English-speaking countries are unlikely to make the distinction between this type of mine and any other type of open-pit or open-cast borrow or gravel pit mining operation. Many quarries fill with water to become ponds or small lakes after abandonment for mining purposes. Others have become landfills. Water-filled quarries can be very deep with water that is often surprisingly cold. Unexpectedly cold water can cause a swimmer's muscles to suddenly weaken; it can also cause shock and hypothermia[1]. These risks make quarry swimming dangerous, especially to kids and teenagers who might swim in a quarry not expecting any risk. Several teenagers and young men and women drown in quarries each year [2][3]. Types of rock extracted from quarries include: Cinder Coquina Blue rock Granite Gritstone Gypsum a mineral Limestone Marble Sandstone Slate
