Anatomy of the foot. The foot is one of the most complex parts of the body. It is made up of 26 bones connected by many joints, muscles, tendons, and ligaments. The foot is susceptible to many stresses. Foot problems can cause pain, inflammation, or injury. These problems can result in limited movement and mobility.
Bricks and tiles. Bricks and tiles are made from clay minerals. When wet, the clay can be shaped, and then fired to make floor, wall, and roof tiles, as well as house bricks. Think about the properties of clay: Easy to shape when wet. Strong and rigid when fired. Impermeable when fired. A thermal insulator.
This dissolved limestone is carried away by the water in solution. Limestone is made of calcium carbonate so this is what is dissolved and carried in the solution. Water will drip from the roofs of caverns very slowly and will therefore evaporate. As it does so solid calcium carbonate is deposited on the cavern roof.uring periods of glaciation, glacial abrasion has scraped away the topsoil to expose the bare rock underneath. Limestone is a sedimentary rock that is made up of horizontal cracks called bedding planes and vertical cracks called joints.
