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

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.

• Lat/Long 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.

What is Latitude?

• For Example:• 37°, 02’,51’’N• This is close to

the latitude where you live.

Y

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

What is Latitude?

• Our latitude and longitude might be:• 37° N• 76° W

Y

90°S

90°N

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.

See If You Can Tell In Which Quarter These Lon/Lats Are Located

• 1. 41°N, 21°E• 2. 37°N, 76°W• 3. 72°S, 141°W• 4. 7°S, 23°W• 5. 15°N, 29°E• 6. 34°S, 151°E

10.24 Bell Ringer

• Europe and Northern Canada are around the same latitude, so therefore they should have similar climate. Why is it that this is not true and that Canada is much colder than Europe?

How currents affect climate?

• Currents carry warm water from the equator and cold water from the poles• Currents change the temperature of

the air above them, which then affects the temperature of the coast

Look at where the warm-water currents and cold-water currents are located. What is the relationship between the temperature of the water currents and the

climate?
