prevents deterioration. BUILDING MATERIALS Aggregate is crushed stone, <span class="highlight">sand</span>, and gravel (small, naturally loose pieces of rock). Asphalt is a mixture of <span class="highlight">sand</span> and a liquid product refined from crude oil, combined with aggregate. Brick is a baked mixture of <span class="highlight">sand</span>, clay, and water. Cement is a fine, gray powder that is made by firing clay and limestone in a kiln. Ceramic tiles are made by firing a mixture of clay, chemicals, and water. Concrete is a mixture of cement, aggregate, <span class="highlight">sand</span>, and water. Dimension stones

further fracturing. Some chemical weathering is a consequence of acids produced by living things growing on the rock. The deterioration of structures such as bridges and statues has increased dramatically in the last few decades, how- ever, because of chemical changes that produce acid rain. Pollution from automobiles and industrial plants adds sulfur dioxide, carbon dioxide, and other gasses to the natural carbon dioxide in the air. 4 <span class="highlight">Sand</span> is used in glass, concrete, asphalt, bricks, and the mortar that holds

This close-up view of the base of a marker shows flaking and chipping caused by physical weathering. 10 This sandstone tablet is disappearing because of chemical weathering.The mineral calcite, which holds the quartz <span class="highlight">sand</span> grains together, dissolves away. The loosened <span class="highlight">sand</span> accumulates at the marker’s base. If acidic precipitation continues to damage the stone, only a pile of loose red <span class="highlight">sand</span> will remain. Leanne Wiberg Leanne Wiberg

4HABITATS - DUNES On low-lying shores, dunes form behind beaches. Dunes look like rolling hills of sand and are blown into place by the wind. Dune Habitat Most of the shores along the US's East Coast and Florida's Gulf Coast are white. The white sand comes from granite, which has been broken down, or weathered, into quartz and feldspar. 9/27/2005 15 This comes from the weathering of volcanic rock. Other beaches are made of cobbles, or small stones. Waves and currents cause these stones to churn and
