1. Describe and explain the relationship between velocity and pressure

2. The word "hurricane" is derived from Hurican, the god of evil of the Carib people of the Caribbean. Hurican was himself inspired by the Mayan god Hurakan, who destroyed humans with great storms and floods. Hurricanes are actually tropical cyclones. This generic term applies to tropical or sub-tropical ocean storms with winds topping 74 miles an hour (65 kilometers an hour). Names such as "hurricane" and "typhoon" refer to cyclones that occur in different regions, but they are the same type of storm.

3. The first image, taken in July 2001, shows narrow sandy beaches and adjacent overwash sandflats, low vegetated dunes, and backbarrier marshes broken by ponds and channels. The second image shows the same location on August 31, 2005, two days after Hurricane Katrina made landfall on the Louisiana and Mississippi coastline. Storm surge and large waves from Hurricane Katrina submerged the islands, stripped sand from the beaches, and eroded large sections of the marsh. Today, few recognizable landforms are left on the Chandeleur Island chain. http://coastal.er.usgs.gov/hurric anes/katrina/photo- comparisons/chandeleur.htmlhttp://coastal.er.usgs.gov/hurric anes/katrina/photo- comparisons/chandeleur.html

4. Mainland Mississippi In the top image, taken in 1998, notice the Deep South Motel to the left and the apartment building to the right. The bottom image shows the same location on August 31, 2005, two days after Hurricane Katrina made landfall. This photo shows that a small portion of the motel is only structure left standing in the area. http://coastal.er.usgs.gov/hurrica nes/katrina/photo- comparisons/mainmississippi.ht mlhttp://coastal.er.usgs.gov/hurrica nes/katrina/photo- comparisons/mainmississippi.ht ml

5. Mainland Mississippi The top image, taken off the coast of Waveland, MS in July 1998, shows several large oceanfront homes, and thick wooded vegetation bordering the sandy beach. The bottom image shows the same location on August 31, 2005, two days after landfall of Hurricane Katrina. All of the houses have been destroyed, and the tennis court behind the house on the far right is no longer recognizable. The vegetation, which should be at its peak in August, has been stripped from the trees. http://coastal.er.usgs.gov/hurricanes/katrina/p hoto-comparisons/mainmississippi.htmlhttp://coastal.er.usgs.gov/hurricanes/katrina/p hoto-comparisons/mainmississippi.html
