2. Well, here's all the answers I decided not to go not in order, but I have the answers to the questions 5. The land formations are very interesting 7. People are littering, and others. 1. Big Bend National Park was authorized by the U.S. Congress on June 20, 1935. 2. Big Bend National Park encompasses more than 800,000 acres in southwest Texas. 3. http://tlc.howstuffworks.com/family/ big-bend-national-park-ga2.htm Go to this link http://tlc.howstuffworks.com/family/ big-bend-national-park-ga2.htm 8. Look at the picture on the right 4. It never said what kind of rock, but I found on another site that said it had metamorphic rock and volcanic rocks 6. Erosion in Big Bend is best defined by rapid runoff and flash-flooding following summer thunderstorms, but there are other active agents of erosion. Water droplets in the atmosphere capture carbon dioxide to form carbonic acid, a very weak naturally occurring acid which has virtually no effect on man. One mineral, however, is vulnerable to attack by carbonic acid: calcite, which comprises the bulk of all limestone in the Big Bend. Every drop of rain that falls on limestone dissolves a tiny bit of calcite which is transported away by runoff, perhaps to a final destination in the Gulf of Mexico – From www.nps.govwww.nps.gov
