1. Chapter 13 Section 3 What are climate zones?
Objective:
Identify and describe the three main climate zones.

2. Latitudes and Climate Zones
climate zone: an area of Earth that has a certain temperature range and similar weather conditions

3. Latitudes and Climate Zones
3 main climate zones:
tropical zone = warm zone near the Equator
between 30°N and 30°S latitude
polar zones = coldest climate zones
above 60°N and below 60°S latitude
temperatures do not go above 10°C
middle-latitude zones = temperatures range from 10°C to 18°C.
between 30° and 60° N and S latitude

5. DEFINE:
What is a climate zone?

6. Solar Energy and Climate Zones
Energy from the Sun is the biggest influence on climate and weather.
the amount of solar energy received at a particular spot is determined by the tilt of Earth on its axis
the tilt influences the angle at which sunlight strikes Earth

7. Solar Energy and Climate Zones
Other factors that can affect the climate of a region include topography, location of lakes and oceans, availability of moisture, global wind patterns, ocean currents, and location of air masses.

8. Rainfall and Climate Zones
In each climate zone, there are smaller climate zones based on rainfall.
In the tropics:
climates can be very arid, or dry
they can also be very humid, or wet
In the polar zones:
the climate is always cold and never humid
The middle-latitude zones have many different climates

9. Rainfall and Climate Zones
affects human life
determines the type of soil and vegetation found in a given area
determines how the land supports living things

10. 2. ANALYZE:
What creates smaller climate zones within the larger ones?

11. 13-3 Classwork Earth is divided into ___ climate zones.
Places with the coldest temperatures are located in the ___ zone.
Places with the warmest temperatures are located in the ___ zone.
The middle-latitude zone has many different combinations of ___ and amounts of rainfall.
The middle-latitude zone is located between ___ N and S latitude.
