Study Notes
Landforms in Florida
- Lakes formed through erosion of limestone; Florida has approximately 7,000 lakes, including Lake Okeechobee.
- Rivers transport and deposit sediment, shaping coastal features like beaches and barrier islands.
- Deltas, typically fan-shaped, form at river mouths as they deposit sediment.
- Coastlines serve as the interface between land and ocean.
- Sand dunes protect coastlines from storms; formed by wave-carried sand and wind action, promoting plant growth like sea oats.
- Wetlands, such as the Everglades, are saturated lands that can be classified as marshes or swamps.
- Coastal lowlands encompass diverse landforms, including beaches, dunes, sandbars, and wetlands.
- Beaches are accumulations of materials deposited by ocean waves and currents.
- Sandbars are ridges of sand or gravel found along coastlines, shaped by water movement.
- Barrier reefs, located offshore, consist of coral colonies and support diverse marine life.
- Ridges mark ancient shorelines, running parallel to the coast, while hills are generally taller features found in Northern and Central Highlands.
Florida's Main Landform Regions
- Florida consists of three primary landform regions: Northern Highlands, Central Highlands, and Coastal Lowlands.
- Northern Highlands is characterized by gently sloping plateaus.
- Both Northern and Central Highlands feature long ridges and hills.
- Coastal Lowlands are rich in coastal features, including beaches, reefs, and wetlands.
Water Bodies and Sinkholes
- Bays, such as Florida Bay and Tampa Bay, are bodies of water formed by shoreline indentations.
- Sinkholes are common in Florida's limestone terrain, with most occurring in Central and North Florida; Southern Florida and the Panhandle experience fewer sinkholes.
- Small sinkholes should be filled with natural materials like rock and clay, while large sinkholes require cement for filling.
- Sinkholes develop over years due to erosion of limestone beneath the surface, often caused by acidic water from rainfall.
- Triggering factors for sinkholes include groundwater overwithdrawal and changes in surface water flow.
- Conditions like droughts or heavy rains following droughts contribute to favorable sinkhole formation.
- The Winter Park Sinkhole was caused by low water levels in Florida’s limestone aquifer; it opened near the residence of Mae Rose Williams.
Notable Events and Locations
- The 2010 Guatemala City Sinkhole was exacerbated by Tropical Storm Agatha, volcanism, and sewage leakage, swallowing a three-story factory.
- The Belize Great Blue Hole is a significant underwater sinkhole.
- Additional oceanic sinkholes include Cave of Swallows (Mexico), Blue Hole (Red Sea), and Dean's Blue Hole (Bahamas).
