Mapping Earth’s Surface

UNIT 2

What types of landforms are around here?

• Homework check• Homework review• Homework quiz• What is the land like around BFS?• Use your smart phones to research one city

outside of Korea. Use each vocabulary term to describe what the city’s land is like. – Topography– Elevation– Landform– Plain– Mountain

Bellwork Quiz

A landform that has high elevation but a mostly flat surface is a a. Plainb. Mountainc. Mountain ranged. Plateau

BFS environment

–Draw a small square to represent BFS.–Choose a word a word that

describes the type of land near your school (flat, hilly, mountainous) and write it next to the square.–Use a compass to determine which

direction is north. Assume north is the top of your paper.–Draw a picture of what the land is

like 5 km in each direction. Describe in words what you drew using terms like flat, hilly etc. – -Scale and Key Practice

Why do we use maps?

• Homework check/homework review• Homework quiz• Share landforms from our chosen

countries• Glue in map to your notebook and

follow the instructions!• If time get started on the history of

maps reading.

1. Color the water light blue, color the mountains purple, color the land light green, and color the key yellow.

2. What is the name of the largest island?3. What is the name of the ocean in the

map?4. Which island is farthest west? 5. Which island is farthest south? 6. About how many miles is it from Hilo

to Captain Cook? 7. What direction would you travel to go

from Hilo to Mauna Kea? 

Map Analysis Questions

What is the history of maps?

• Read about different historical maps with a partner• Make your map foldable

Bellwork Quiz

• Over time map technology has allowed us to see the world more accurately. Which maps were improved by the printing press?A. Early MapsB. Medieval MapsC. Renaissance MapsD. Modern Maps

Bellwork Quiz

The equator divides the Earth into two equal halves called:

A.GlobesB.HemispheresC.DegreesD.Pixels

History of Maps FoldableStep 1: Title the page “History of Maps”

Step 2: Make your foldable and glue it on the page

Step 3: The flaps should be labeled: Early Maps, Medieval maps, Renaissance maps, and Modern maps (leave room for pictures!)

Step 4: Draw a sample map from each era on the front flap.

Step 5: The inside flap should describe the type of map in your OWN WORDS.

Step 6: On the bottom of the foldable you should answer the question: How has map technology influenced our view of the Earth?

How do we use latitude and longitutude?

• Latitude and Longitude notes• Latitude and longitude practice

game in pairs• Paste globe into journal: Label

– North Pole– South Pole– Equator– Prime Meridian– Western Hemisphere– Eastern Hemisphere– Northern Hemisphere– Southern Hemisphere– longitude– latitude

Typical Graph

• This is an example of a typical graph we are all familiar with.

• The graph is made up of different “points” with lines that connect the points.

Typical Graph • Each point has two values:

• The “X” value that runs along the horizontal “X” axis

• The “Y” value that runs along the vertical “Y” axis

Y axis

X axis

Typical Graph• X value is always

stated first• Followed by the Y

value• The “origin” is the

point where the 2 axes intersect with a value of (0,0)

(0,0)

(3,8)Y

X

(9,5)

Typical Graph• A point can also

have negative (-) values

• Negative X values are to the left of the origin (0,0)

• Negative Y values are below the origin

X

Y

(-X,+Y)

(+X,-Y)

(+X,+Y)

(-X,-Y)

(0,0)

East West, North South on The Earth

• Let the X axis be the Equator.

• Let the Y axis be the Prime Meridian that runs through Greenwich outside of London.

• Latitude and Longitude are the 2 grid points by which you can locate any point on earth.

Y

X

East West, North South on the Earth

• Let each of the four quarters then be designated by North or South and East or West.

N

S

EW

East West, North South on the Earth• The N tells us we’re

north of the Equator• The S tells us we’re

south of the Equator.• The E tells us that

we’re east of the Prime Meridian.

• The W tells us that we’re west of the Prime Meridian.

(N, W) (N, E)

(S, W) (S, E)

East West, North South on the Earth

• That means all points in North America will have a North latitude and a West longitude because it is North of the Equator and West of the Prime Meridian.

(N, W)

Prime Meridian

East West, North South on the Earth

• What would be the latitude and longitude directions in Australia?

Prime Meridian ?

If you said South and East , you’re right!

What is Latitude? • Latitude is the distance from the equator along the Y axis.

• All points along the equator have a value of 0 degrees latitude.

• North pole = 90°N• South pole = 90°S• Values are expressed in

terms of degrees.

Y

X

90°S

90°N

What is Longitude?

• Longitude is the distance from the prime meridian along the X axis.

• All points along the prime meridian have a value of 0 degrees longitude.

• The earth is divided into two parts, or hemispheres, of east and west longitude.

Y

X

180°W 180°E

What is Longitude?

• The earth is divided into 360 equal slices (meridians)

• 180 west and 180 east of the prime meridian

Y

X

180°W 180°E

So Where is (0,0)?• The origin point

(0,0) is where the equator intersects the prime meridian.• (0,0) is off the

western coast of Africa in the Atlantic Ocean.

• In your notebook answer the following question:– If you were in charge of deciding where the state borders would be for an area of land, HOW WOULD YOU DECIDE WHAT THEY WOULD BE?

Reading Check/Prediction…

• Reading check page 26–What information does a topographic

map give you?

represented on a topographic map?

steepness• D. There is no way to tell!

-What do close contour lines mean?-What do spread out contour lines mean?-What information can you conclude from this map?-How tall is Mr. Passaconway peak?

How can you MAKE a topographic map?

• Collect your mountain• Make a topographic map! (page 31)• Analysis questions: 1. Compare your map with the clay landforms. How

are they alike? How are they different? 2. Looking at your topographic map, how can you

tell which parts of your model have a steep slope? A gentle slope?

3. How can you tell from the map which point on the hill is the highest?

4. How could you improve your map as a model of the landform?

Time to create!

• Make a clay model of your topographic map.–Study the picture–Make a sketch–Make your model–Describe in words

• Review for quiz!
