Presentation Transcript

2. Mountains Mountain- an elevated landform characterized by steep slopes; it is usually part of a chain of mountains.

3. How Mountains are Formed Mountains form in different ways- Strong movements in the earth under the ground form mountains. The force of these movements pushes rock layers upward and this forms mountains and mountain ranges.

4. Mountain Parts

5. Mountain Vocabulary Hill- Moderately high landform whose slopes follow a gentle incline. Cliff- A steep and fairly smooth slope. Peak- mountain whose summit forms a cone or point. (triangle-like) Summit- The highest point on the mountain. Ridge- Long narrow section at the highest point on a mountain.

6. Mountains Characteristics: Erosion and Weathering Older Mountains- lowers, more flattened, smoother Newer Mountains- higher, rigid, rocky Why do you think you can see a difference between older and newer mountains? The reason is because of erosion and weathering. Overtime the older mountains have been worked down, and slowly become flat and/or smooth.

8. Mountains Mountains can be found through out the United States. There are a total of 75 mountains in the United States. There are TWO main mountain ranges: 1)The Rocky Mountains which run from the Western United States through Canada. 2) The Appalachian Range which runs from the Southeast U.S. and northward to Canada. Does anyone know if Alabama has a mountain? If there is one, do you know the name of it?

12. Appalachian Mountains The Appalachian Range runs through Alabama, Georgia, Tennessee, Kentucky, Virginia, West Virginia, Maryland, South Carolina, North Carolina, and Pennsylvania. Activity- each student is given a copy of a U.S. map, with each state name shown and outlined. The students will color in the states the Appalachian range runs through in red.

13. Rocky Mountains

14. Rocky Mountains The Rocky Mountains span over 8 states: Arizona, Colorado, Idaho, Montana, Nevada, New Mexico, Utah, and Wyoming. Rocky Mountain Activity- each students is given a map of the united states and they will color in the Rocky Mountain States. In blue.

15. Mt. Rushmore Mt. Rushmore is located in South Dakota. Locate South Dakota on your map. Now label it with the color green. During the early 1900’s, the U.S. was growing very fast. People were traveling from the East Coast to the West coast. Many were passing by North and South Dakota, not stopping. The people in South Dakota wanted a tourist attraction that would bring in more tourists that were passing through the state. The South Dakota Historical Society decided they should build a huge memorial carved from rock and it would bring more visitors to the area. The increased number of visitors would bring in more money also.

19. Mt. Rushmore Mt. Rushmore is made out of a type of rock called granite. Granite is especially good for carving. The carver Gutzon Borglum decided to carve president’s faces onto the side of the mountain. He decided that George Washinton, Thomas Jefferson, Abraham Lincoln, and Theodore “Teddy” Roosevelt should be carved on the mountain.

20. Mt. Rushmore George Washington- 1st president & leader of our country. Thomas Jefferson- purchased land from France, which doubled the size of the U.S. Abraham Lincoln- he led the country during the Civil War. Theodore “Teddy” Roosevelt- he had the U.S. build a waterway in Central America, the waterway is called the Panama Canal. He also was from South Dakota.

22. Good citizens As a review of what we just learned about the presidents, can someone raise their hand and tell me if the presidents were good citizens? Also give me an example of why. How can we be good citizens? Raise your hand and give me an example. Do you remember that we said weathering and erosion caused mountains to become more smooth and to flatten out? What can we do as “good citizens” to make sure Mt. Rushmore isn’t damaged? How can we protect Mt. Rushmore?

23. Damage to mt. rushmore Each year Mt. Rushmore is cleaned and checked for cracks or damage. Rock wears away over time from weathering and erosion. Also some people leave trash around the mountain or spray paint it. Do you think these are examples of showing good citizenship or bad citizenship?
