Study Notes
Topography
- Topography refers to the elevation, relief, and landforms of a region.
- It informs architects, engineers, and soldiers in planning projects and navigating the land.
- Topographic maps visualize an area's topography.
Florida's Landforms
- Florida's sinkholes are caused by the dissolution of limestone bedrock.
- Coastal plains characterize Florida's beaches, known for low elevations and flat land.
- Florida's north and central regions feature hills and ridges, with Sugarloaf Mountain being the most prominent part of the Lake Wales Ridge (325ft above sea level).
- Lake Okeechobee is Florida's largest lake, overflowing during the rainy season and feeding the Everglades.
- The Florida Keys are a chain of about 1,700 islands, primarily formed by exposed coral reefs with accumulated sand.
Weathering, Erosion, and Deposition
- Weathering is the process of breaking down Earth's surface into smaller pieces.
- Weathering agents include water, plants, air, chemicals, and animals (including humans).
- Erosion is the process of carrying away weathered rock.
- Deposition occurs when eroded sediment settles in new locations, reshaping the land.
- The cycle of weathering, erosion, and deposition is continuous.
Types of Weathering
- Physical weathering breaks large rocks into smaller ones without changing their chemical composition.
- Abrasion: The wearing away of rock by sand or rock-on-rock friction.
- Animal Activity: Animals, including humans, dig and disrupt rock, loosening soil and breaking apart rocks.
- Frost Wedging: The freezing and thawing of water in rock cracks causes expansion and breakage.
- Plant Growth: Root growth in rock cracks widens them, ultimately breaking the rock.
Chemical Weathering
- Chemical weathering changes the chemical composition of rocks.
- Acid Rain: Acids from burning fossil fuels dissolve in water vapor, creating acid rain that accelerates weathering.
- Carbon Dioxide: Carbon dioxide dissolved in water forms carbonic acid, which erodes rock, particularly limestone and marble.
- Oxygen: Oxygen reacts with iron-rich minerals in rocks, causing rust (iron oxide), which weakens the rock and makes it more susceptible to further weathering.
