Landforms, Rock Cycle, & Human Impacts  Landform Formation of landform Picture of Landform Beach/Coastline Formed by weathering in mountains/inland, eroded, and deposited by rivers Dune Formed by wind eroding sand and depositing into large piles Delta Formed by the slowing down of a river near a large body of water and depositing sand/sediment River Formed by the surface runoff from precipitation of melting snow  Landform Formation of landform Picture of Landform Mountain Formed by two tectonic plates pushing against each other (convergent) Glacier Formed from a large moving mass of ice Lake Formed at the end of rivers collecting water Sinkhole Formed by water chemically weathering limestone beneath the surface and creating a large hole What is the difference between Weathering: Breakdown of rock weathering, erosion, and Erosion: Movement of sediment from broken down rock deposition? Deposition: The dropping of sediment in a NEW place Need help? Watch this video Weathering, Erosion, Deposition Song What is the difference between Physical (mechanical) weathering breaks down rock by physical (mechanical) and natural forces such as wind or rain. Chemical weathering breaks down rock by chemical reactions such as acid rain and chemical weathering? Give rust. examples of each Need help? Watch this video For each of the following scenarios, identify whether it describes weathering, erosion, or deposition. If it is weathering, specify whether it is physical (mechanical) or chemical. YOU CAN PUT MORE THAN ONE A river slowing down and depositing sediment forming a delta Deposition Water seeps into cracks in a rock, freezes, and expands, causing the rock to break apart over time. This Physical Weathering is known as frost wedging. Acid rain reacts with limestone, causing it to dissolve and form caves. Chemical Weathering Strong winds in a desert pick up and carry away small particles of sand, gradually shaping sand dunes. Erosion & Deposition (THIS ONE HAS 2) Tree roots grow into the cracks of a rock, exerting pressure and eventually causing the rock to split Physical Weathering apart. A river flows rapidly through a canyon, carrying away small rocks and sediment, gradually deepening Erosion & Physical and widening the canyon. weathering Ocean waves carry sand and pebbles onto the shore, creating a sandy beach over time. Erosion & Deposition Describe how igneous rock can change into The igneous rock is weathered and eroded into sedimentary rock sediment. The sediment is compacted and compressed into sedimentary rock. Describe how metamorphic rock can be changed The metamorphic rock melts into magma and then into igneous rock cools and crystallizes. Describe how igneous rock can be changed into The igneous rock is exposed to heat and pressure. metamorphic rock Describe how sedimentary rock can be changed The sedimentary rock is exposed to heat and into metamorphic rock pressure. Describe how igneous, metamorphic, or Weathering and Erosion sedimentary rock can be changed into sediment  Florida Landforms What type of landforms are NOT found in Florida? Mountains and glaciers (you can also put volcanoes) What type of rock is the plateau of Florida made Limestone, sedimentary out of? Is this rock sedimentary, igneous, or metamorphic? How are sinkholes formed? Why are they common Chemical weathering causes a cavity or cavern to in Florida? collapse What can form after a sinkhole fills with water? Lakes Does Florida have dunes? If so where and how Yes, near the beaches are they formed?  Florida Landforms Florida is surrounded by water on 3 sides and is still Why is Florida considered a connected to the mainland peninsula? The everglades are a wetland and they are What are the Everglades and important because of water filtration, flood control why are they important? (absorbs and releases water slowly), and habitat A spring is a natural opening in the ground where What is a spring? groundwater flows to the surface. The water comes from an aquifer. The Everglades is a subtropical wetland ecosystem spanning two million acres across central and south Florida. Originally the Greater Everglades ecosystem had a large diversity of habitats connected by wetlands and water bodies. The Everglades ecosystem provides drinking water for one-third of Floridians and irrigation for much of the state's agriculture. Since the 1800s, humans have been altering the Everglades landscape by changing the flow of water (shown by the maps below) How have humans impacted the Everglades environment, habitats, and wildlife? Changing Water Flow: By altering the flow of water in the Everglades, humans have caused the ecosystem to lose about 70% of its water supply. This significant reduction has affected the habitats of many plants and animals, leading to a decline in biodiversity. Urbanization: Urban development has destroyed natural habitats, displacing many plant and animal species. Additionally, urbanization has introduced pollutants such as fertilizers and pesticides into the environment, further degrading the quality of habitats and water. Introduction of Non-Native Species: Humans have introduced non-native species to the Everglades, which often outcompete native species for resources. This has disrupted the natural balance of the ecosystem, leading to declines in native populations and changes in habitat structure. Human Behavior Deforestation, Urbanization, or Describe how this behavior may Desertification impact the Earth (Erosion, air quality, water quality, change water flow) Deforestation Loss of habitat Increased CO2 in the atmosphere Soil erosion and reduced soil fertility Increased flooding Desertification Reduced ability to grow crops Loss of vegetation Loss of habitat for plants and animals Urbanization Loss of habitat for plants & animals Increased surface runoff Higher risk of floods More polluted Water
