1. Objective 3.1 Unit Notes

3. The ROTATION of the Earth causes day and night.

4. Earth's Rotation around its Axis
Earth rotates around its own axis
Through 360° once every 24
hours. This is the cause of day
and night.
The Earth's polar axis tilts at an
angle of 23,5° with its orbital
plane around the sun. This
inclination (tilt) is responsible for
the climate changes and the
seasons experienced on
Earth.   

5. As the Earth revolves around the Sun, the part of Earth
that points toward the Sun changes. The part of the
Earth pointing toward the Sun is having summer and the
part of the Earth pointing away from the Sun is
experiencing winter.

7. The equator always
receives DIRECT
sunlight and is
therefore always
hotter. The poles
always receive
ANGLED (indirect)
sunlight and are
always colder.

8. The Earth is divided
into 3 major climate
zones. These zones
are divided based on
temperature and
precipitation.

9. Factors that Influence Climate
1.Latitude – how far an area is away from the equator. (The further north or south of the equator you are, the colder the climate will be.)

10. Tilt of the Earth – Earth is tilted at a 23. 5 degree angle
Tilt of the Earth – Earth is tilted at a 23.5 degree angle. Areas around the equator receive direct sunlight year round.
3. Prevailing Winds – winds from different areas carry different temperature air.

11. Large Bodies of
Water – water holds
heat better than land
and the prevailing
winds carry the
heat/cold to ot
her
areas.
5. Ocean Currents – currents carry warm or cold air to other parts of the world.

12. Mountains – affect the temperature and amount of precipitation of an area.
