• Orbit- the path of the earth around the sun
• Axis- An imaginary line that runs from
north to south pole through the middle of
the earth
• Hemisphere- half of a sphere. There are 4
North, South, East, West
Questions
1. In what two ways does the earth move?
Rotates and Revolves
2. What causes the changes in the
seasons?
The tilt of the earth on it’s axis
3. In what ways is Aristotle correct in his
ideas about the earth?
Aristotle was correct in saying that the earth
was a sphere.
4. What do we know about the earth that
Aristotle did not know?
That the earth is in constant motion
Lesson 2
• GridA system that uses lines of longitude and latitude to find
location
• Latitude –
lines that run east and west on the globe that measure
distances north and south of the equator
• Parallel –
Another way to describe the lines of latitude that never
intersect
• LongitudeLines that run north and south on the globe that measure
distances east and west of the prime meridian
Vocabulary continued
• Meridian
Another term to describe the lines of longitude
• Prime Meridian
The major line of longitude from which all other
lines are measured. 0 degrees longitude
• International date line
The point at which the day begins
Questions
1. What were Ptolemy's contributions to the
study of geography?

world
3. What special meridians divide the world
into eastern and western hemispheres?
The Prime Meridian and the International
Date Line
Questions
4. What are the 2 kinds of lines that form a
grid that Ptolemy drew on his map?
Lines of longitude and lines of latitude
5. Why are grids placed on a map?
To find location
Vocabulary
• Odometer-A device used in measuring distance
• Scale-Shows the relationship between a model size and
the actual size
• Elevation-The distance on land above sea level
• Altitude- The distance above sea level
• Contour Line- A way to show on a map the distance
above sea level.
Questions
1.What was the reason for Ptolemy's mistake
about the size of the earth?
He had no way to know with the technology
available to him
2. How did the Roman odometer work?
It was a device with a wheel and a round stone.
3. What is the purpose of the map scale?

map?
Color relief and contour line
Vocabulary
• Cartographer
A person who makes maps
• Satellite
An object that is made to travel around the
earth
Questions
1. How do photographs taken from directly
above the earth surface help make better
maps?
Photographs have an exact degree on
accuracy
2. How has exploration of space helped
cartographers make better maps?
It removes distortion by getting a look at the
entire surface
Vocabulary
• ProjectionA way to show a drawing of the earth on a
flat surface
• Distortion
A difference in what is true and what is
perceived.
Questions
1. Why do map makers have a problem
making a flat map of the world?
It is very difficult to create a flat model of a
round object without distortion.
2. How has exploration of space helped
cartographers make better maps?
Satellite pictures give us a real photo and a
true representation of the earth’s surface
