ESC1000 Virtual Field Trip to Dames Caves, Citrus County, Florida View the video here: https://www.youtube.com/watch?v=QuUWbKYFh38 1. This area is an example of karst geology. What type of rock is typical of karst geology? What role does groundwater play in the formation of karst and, in particular the formation of caves? The type of rock that is typical of karst geology is soluble rocks like dolomite, limestone, and gypsum. In groundwater there is carbonic acid throughout the moving water that causes the surface of the bedrock to dissolve and create a cave formation. 2. How are caves part of our aquifer? How much water does our aquifer discharge each day? The reason caves are part of our aquifer is because of their karst geology. Our aquifer discharges over 8 billion gallons of water daily. 3. How can sinkholes be related to caves? Sinkholes are related to caves because over time as the dissolving limestone and other rocks from the caves fall onto the surface a sinkhole can be formed. Most sinkholes are formed from the karst process. 4. Describe how the stalactites look in these caves? Why do you think that they are so small? In these caves stalactites look like small shriveled up stone pieces in the same shape as an icicle. I believe stalactites are so small because of the tourist travelling amount is very common and the Dames caves mainly are subject to karst landforms which typically are known for smaller stalactites. 5. What minerals are common in the caves in Florida? Minerals that are common in the Florida caves are phosphate, gypsum, dolomite, and calcite. 6. How are the animals that live in caves different from their counterparts that live on the ground surface? Animals that live in caves are different from their counterparts that live on ground surface because the functionality of their eyesight has been decreased or lost because of the lack of light found in caves.

ESC1000 Beaches and Coastal Erosion PART 1: Northeast Florida Beaches Virtual Field Trip by Joann Mossa The questions below are based upon the virtual field to three northeast Florida beaches, linked here: https://fcit.usf.edu/florida/teacher/science/mod2/resources/coastal.pdf Use the PowerPoint your textbook to answer the questions. 1. What are the two principle materials found on these beaches? List the principle mineral(s), the grain size, and the source of the sediment. The two principal minerals found on these beaches are quartz and another darker mineral that is denser than quartz. The minerals have a grain size of 1/16 mm and 2 mm. The source of sediment is sand. 2. Describe the beaches of Northeastern Florida. Include the width and slope of the beaches in your description. The beaches in Northeastern Florida have several sand dunes to which many forms of vegetation are created to reduce coastal erosion. In my opinion, the width of the Northeastern Florida are long and narrow and the slope of the beach and its sand dunes are dependent on the wind patterns, tides, and the movement of sand. 3. Describe the dunes in Northeastern Florida. What are the natural means of stabilizing dunes? How does this work? 4. What agents and processes move the dunes? 5. Did you see any evidence of dune erosion? What caused the erosion? 6. These beaches are on barrier islands. Compare the beaches on the ocean side of the islands with the beaches on the lagoon (river) side of the islands. How are they similar and how do they differ in width, slope, composition of the sediments, and grain size of the sediments? 7. What are the agents and processes that move sand on the beaches? 8. How are the beaches and the dunes related? 9. How have people tried to slow down beach erosion in this area? 10. Is this an active or passive margin? Give some reasons to support your answer. PART 2: Coastal Erosion 1. How structural and nonstructural methods used to try to slow coastal erosion?   2. Describe the different methods, their effects, and effectiveness.
