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

3 Lanforms

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

5 Examples of Mountains Rocky Mountains Himalayan Mountains Adirondack Mountains

6 Plains Plains are broad, nearly level stretches of land that have no great changes of elevation Plains are broad, nearly level stretches of land that have no great changes of elevation Plains may be found along the coast or inland 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 Coastal plains: generally rise from sea level until they meet higher landforms such as mountains or plateaus Inland plains: may found at high altitudes Inland plains: may found at high altitudes Flood plains are the floor of a river valley beyond the riverbed 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 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 Plateaus are large highland areas of fairly level land separated from surrounding land by steep slopes Some lie between mountain ranges Some lie between mountain ranges Some are basaltic, forming from many lava flows Some are basaltic, forming from many lava flows Other are formed by upwarped folding Other are formed by upwarped folding Plateaus may also be formed due to eroding land Plateaus may also be formed due to eroding land Weathering and erosion take affect on the upland, creating slopes Weathering and erosion take affect on the upland, creating slopes

9 Examples of Plateaus Island in the Sky- Utah Kukenan Tepui- Venezuela Tibetan Plateau

10 Florida Landforms Florida consists of these major landforms: Florida consists of these major landforms: 1.Beaches 2.Aquifers 3.Sinkholes 4.Caverns 5.Coastal plains 6.Upland (hilly areas) 7.Swampy Everglades 8.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 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 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 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 Sinkholes are natural draining systems formed by chemical weathering Limestone is dissolved, forming sinkholes Limestone is dissolved, forming sinkholes

13 Caverns Caverns are natural underground spaces large enough for humans to enter Caverns are natural underground spaces large enough for humans to enter They form naturally by weathering of rock and often extend deep underground 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 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. 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. Swamps are types of freshwater wetlands that have spongy, muddy land and a lot of water. Many trees and shrubs grow in swamps 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 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) 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. 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 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 The Florida Keys are an example of an archipelago

17 Optional Project (for those who would like to boost their project grade) Create a slide PowerPoint about 3 or more landforms following these guidelines: Create a slide PowerPoint about 3 or more landforms following these guidelines: 1.The first slide should include: Name, Date due, period Name, Date due, period Name of Landforms included in your PowerPoint Name of Landforms included in your PowerPoint 2.Include the following information about your landforms: Description, how they are formed, picture(s), examples of your landform on Earth Description, how they are formed, picture(s), examples of your landform on Earth 3.The last slide should include a list of websites or references of where you found information 4. your PowerPoint presentation to by A: 1/11 B: 1/14 with “Landform Project” written in the subject line of your
