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

Lanforms

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

Examples of Mountains

Rocky Mountains

Himalayan Mountains

AdirondackMountains

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

Examples of Plains

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

Examples of Plateaus

Island in the Sky- Utah

Kukenan Tepui- Venezuela

Tibetan Plateau

Florida 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)

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

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

Caverns

Caverns are natural underground spaces large enough for humans to enter

They form naturally by weathering of rock and often extend deep underground

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.

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)

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

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:1. The first slide should include:

Name, Date due, period 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

3. The last slide should include a list of websites or references of where you found information

4. Email your PowerPoint presentation to [email protected] by A: 1/11 B: 1/14 with “Landform Project” written in the subject line of your email
