  1. Landforms Mr. Perez

  2. What is a landform? • A landform is a natural feature of the landscape or natural physical features of the Earth’s surface • Examples include: • Valleys • Plateaus • Mountains • Plains • Hills • Beaches • Canyons • Deserts • Rivers • Straits • Archipelago • Peninsulas • Swamps

  3. Lanforms

  4. Mountains • Mountains are formed when two plates converge or collide and begin to rise • Some times, mountains are formed by the process of weathering and erosion. • Mountains are broken down by wind, water and ice • This causes the shape of the rock to change • Other times, mountains can be formed by volcanism • Volcanism is any volcanic activity

  5. Examples of Mountains Adirondack Mountains Rocky Mountains Himalayan Mountains

  6. Plains • Plains are broad, nearly level stretches of land that have no great changes of elevation • Plains may be found along the coast or inland • Coastal plains: generally rise from sea level until they meet higher landforms such as mountains or plateaus • Inland plains: may found at high altitudes • Flood plains are the floor of a river valley beyond the riverbed • These are formed by mud, sand and silt that are carried off by the river as it erodes the land upstream

  7. Examples of Plains

  8. Plateaus • Plateaus are large highland areas of fairly level land separated from surrounding land by steep slopes • Some lie between mountain ranges • Some are basaltic, forming from many lava flows • Other are formed by upwarped folding • Plateaus may also be formed due to eroding land • Weathering and erosion take affect on the upland, creating slopes

  9. Examples of Plateaus Tibetan Plateau Island in the Sky- Utah • KukenanTepui- Venezuela

  10. Florida Landforms • Florida consists of these major landforms: • Beaches • Aquifers • Sinkholes • Caverns • Coastal plains • Upland (hilly areas) • Swampy Everglades • Florida Keys (archipelago) (Peninsula)

  11. Beaches • Beaches are formed by the constant battering of the ocean, wind and other natural conditions wear down the rock and other materials on shore

  12. Aquifers & Sinkholes • Aquifers are bodies of permeable rock that can transmit or contain groundwater • The major source of ground water supply in Florida is the Floridan Aquifer System, which underlies the entire state • Sinkholes are natural draining systems formed by chemical weathering • Limestone is dissolved, forming sinkholes

  13. Caverns • Caverns are natural underground spaces large enough for humans to enter • They form naturally by weathering of rock and often extend deep underground

  14. Upland (hilly areas) • Upland, or hilly areas, are raised areas of land • In Florida, hilly areas are found in the northern panhandle and central part of the state.

  15. Swampy Everglades • Swamps are types of freshwater wetlands that have spongy, muddy land and a lot of water. • Many trees and shrubs grow in swamps • Before humans began developing land in South Florida, almost 11,000 square miles was covered in the swampy Everglades • The Everglades is the only place where alligators and crocodiles can exist side by side (because of the salt and freshwater mix)

  16. Florida Keys (archipelago) • An archipelago is a group or chain of islands clustered together in a sea or ocean. • Some archipelago are formed due to volcanic activity, while others can form due to weathering and erosion of land • The Florida Keys are an example of an archipelago

  17. Optional Project (for those who would like to boost their project grade) • Create a 10-15 slide PowerPoint about 3 or more landforms following these guidelines: • The first slide should include: • Name, Date due, period • Name of Landforms included inyour PowerPoint • Include the following information about your landforms: • Description, how they are formed, picture(s), examples of your landform on Earth • The last slide should include a list of websites or references of where you found information • Email your PowerPoint presentation to eperez@miamiartscharter.net by A: 1/11 B: 1/14 with “Landform Project” written in the subject line of your email
