1. Exploring Earth’s Surface
Chapter 1
Section 3

2. Standard
S.6.2
Topography is reshaped by the weathering of rock and soil and by the transportation and deposition of sediment.

3. Anticipatory Set

4. Language of the Discipline
Topography
Map
Elevation
Scale
Relief
Degree
Plain
Latitude
Mountain
Longitude
Plateau

5. Topography (Input) Definition- is the shape of the land.
It may be flat, sloping, hilly or mountainous
Topography includes the area’s elevation, relief and landforms.
Elevation- the height above sea level of a point on Earth’s surface
Relief- the difference in elevation between the highest and lowest parts of an area
Look at diagram on page 21

6. Topography (Input)

7. Types of Landforms (Input)
They vary in size and shape
Plains- a landform made up of flat or gently rolling land
If it is by the coast it is called a costal plain
If it is not by the coast it is called an interior plain

8. Plains (Input)

9. Mountains (Input)
2. Mountains- a landform with high elevation and high relief. They are normally in a mountain range
Mountain Range- mountains that are closely related in shape, structure and age
Mountain ranges in a long, connected chain form a larger called unit called a mountain belt (Rocky Mnts)

10. Mountains (Input)

11. Plateaus (Input)
3. Plateaus- a landform that has high elevation and a more or less level surface
Streams and rivers cut into the surface (hardly smooth)
Columbia Plateau- rocks are stacked 1,500 meters thick

12. Plateaus (Input)

13. What is a Map? (Input)
Map- a flat model of all or part of Earth’s surfaces as seen from above.
Maps are drawn to scale and use symbols to represent topography and other features on Earth’s surface.
Scale- relates distance on a map to a distance on Earth’s surface. It is given as a ratio.
Mapmakers use shapes and pictures called symbols for features of Earth’s surface.

14. Map (Input)

15. Map’s Continued (Input)
A symbol can represent a river, lake, mountain, or play
A symbol can also stand for a man made feature- a highway, city or airport
Map Key/Legend- is a list of all of the symbols used on the map and their meanings
Maps also include a compass rose or north arrow
North is usually located at the top of the map

16. Legends/Keys (Input)

17. Earth’s Grid (Input)
You need a grid to help you keep track of where you are
To locate positions on Earth’s surface, scientists use units called degrees.
Each degree is a measure of an angle formed by lines drawn from the center of Earth to points on the surface.

18. Earth’s Grid (Input)

19. Equator (Input)
Halfway between the North and South poles is an imaginary line that circles the Earth
This equator divides the Earth into a Northern Hemisphere and a Southern Hemisphere.
Hemisphere- one half of the sphere that makes up Earth’s surface
Look at wall map. Locate equator, Northern and Southern Hemispheres

20. Equator (Input)

21. Prime Meridian (Input)
Another imaginary line
Makes a half circle from the North Pole to the South Pole.
If they are East of the line, they are in the Eastern Hemisphere.
If they are West of the line, they are in the Western Hemisphere.
Look at wall map, locate prime meridian, and East and West Hemispheres

22. Prime Meridian (Input)

23. Locating Points (Input)
The lines of latitude and longitude on a map form a grid that can be used to find locations anywhere on Earth.
The equator is the starting line to meausre latitude
North to South
The Prime meridian is the starting line to meausre longitude
East to West

24. Using Latitude and Longitude (Input)
Any location on Earth can be expressed in terms of the latitude and longitude lines.
Look at page 27 and picture of globe
Explain how they found London
What would be the latitude and longitude for Los Angeles?
What would be the latitude and longitude for Sydney?

25. Longitude and Latitude (Input)

26. Checking for Understanding
True or False
Elevation and relief are part of an area’s elevation?

27. true

28. Checking for Understanding
What is the landform that has high elevation but a level surface (relief)?

29. Plateau

30. Checking For Understanding
Draw a world map and label the equator and the prime meridian
