1. Ch. 2 Notes Day 2

2. Objectives
SWBAT identify the position of the prime meridian and equator and explain their significance.
SWBAT define and identify latitude and longitude lines on a map
SBAT define and estimate the latitude and longitude of a city/location on a map

3. Mapping the Earth
The Earth is huge, so we need a special system to determine where we are on it
This special system also needs a reference point.
“Hey Bill, come meet us at the malt shop.”
“Sure gang, where is it?”
“It’s only a few blocks.”
“A few blocks from what????”
NO REFERENCE POINT, NO MALT FOR BILL. 

4. The Two Reference Points on the Earth
Just like the x-axis and y-axis in math class, we have the following lines…

5. The Equator (Earth’s X-axis)
The Equator is a “imaginary” horizontal line that passes through the middle of the Earth, splitting it into two equal-sized hemispheres.
Northern Hemisphere
Southern Hemisphere

6. Latitude- Horizontal, parallel lines on a globe, that describe how North or South you are from the Equator. Also called a parallel.
60° North
Latitude angles are measured from the center of the earth. Maximum angle of 90 Degrees.
Never negative!
30° South
