ObjectiveToday we are going to be learning
about what climate is and the different climate zones.
Factors that affect climate.
Factors that affect climate?There are different factors that affect
the climate, which areLatitude
The range of temperature increases and decreases with the distance from the equator.
Why? Because the sun rays are scattered over a larger area of land as we move away from the equator, the curved surface of the earth causes this to happen.
The polar regions are colder due to the fact that sun rays have to travel further
Factors that affect climate cont.
WindsIf the wind is being blown from a hot area, the temperatures will rise, whereas if the wind is being blown from a cold area, the temperatures will decrease.
AltitudeThe height causes the temperatures to decrease.
The air is less dense and it cant hold the heat as easily
Factors that affect climate cont.Distance from the sea (continentally)
Land heats and cools faster than the sea, this is a fact. Because of that the temperature in coastal areas are lower than area inland. The winter is mild and the summer is cool on the coast. In the inland areas, the temperatures are high in the summer and cold in the winter.
AspectThe warmer areas are the slopes that are
facing the sun. the south facing slopes in the northern part of the hemisphere are the warmest, for the most part.
Tropical Zone cont.A tropical Zone is wet and hot all year round
The part of the Earth’s surface between the Tropic of Cancer and the Tropic of Capricorn
Temperate Zone cont.
Temperate zones consist of cold winters and mild summers
This zone is located in most of Europe and America, New Zealand, southern Chile and east Asia.
Fun Fact: This zone accounts for 7 percent of the world’s surface land and 4/10ths of the population
Polar/Tundra Climate cont.The polar zone is very cold AND very dry all
year roundThe winters are long and dark in the polar
zone.In the tundra, the temperature can rise
above freezing, but not in the ice cap climate
Fun Fact: The coldest temperatures that are ever recorded on Earth was -88 degrees Celsius, -125 degrees Fahrenheit, in Antarctica.
Dry/Desert Climate cont.The dry/Desert zone is dry AND hot all year
round These climates are formed by high-
pressure zones in which the cold air descends. The descending air soon becomes warm, but instead of releasing rain, the heat that is coming from the ground evaporates the water before it has a change to come down as rain. The ground is really hot because the rays of the sun are directed directly overhead. There isn’t much of an atmosphere to protect it from radiant energy.
Ending QuestionDescribe the pattern you see of the climate zones heading north of the equator, and south of the equator
