Homework Oceanography and Climate Review due Friday Feb 12 th (test day!!)
Learning Targets I can define the term climate and explain the factors that influence the climate of an area. I can identify the location and characteristics of four basic climate zones. I can interpret Climate Graphs to determine climate zones.
Review: Using a blank piece of paper sketch the equatorial Pacific. - Draw arrows to show the Trade Winds - Draw a circle of warm surface water during a normal year - Write the normal climate conditions next to each continent
Climate Average weather conditions at a location over a long period of time. Determined by temperature and amount of precipitation.
Prediction What are some factors that affect climate?
Why do the following locations have different climates? Brazil, South America Russia
1. Latitude Uneven heating from equator to poles
Why do the following locations in France have different climates? Tignes, France
2. Elevation Temperature drops the higher your elevation
Why do the following locations at similar latitudes and elevation in the U.S. have different climates? Portland Minneapolis
3. Distance from Large Bodies of Water (oceans, seas, large lakes) Oceans hold their heat longer creating mild coastal climates (ex: Portland see graph below)
Why do the following coastal locations at similar latitudes have different climates? Newfoundland Scilly Isles
4. Ocean Currents Warm-water currents warm coastal climates Ex Labrador Current and Natashquan Cold-water currents cool coastal climates. Ex London and Gulf Stream
FOUR Basic Climate Zones Based on Temperature & Precipitation Usually found at the latitudes listed below Tropical (0-25 degrees latitude) Desert (Arid) (25-40 degrees latitude) Temperate (40-60 degrees latitude) Polar (60-90 degrees latitude)
FOUR Basic Climate Zones
Reading a Climate Graph READ ONLY - Climate graphs are used to illustrate the average temperature and rainfall experienced at a particular place over the course of a year. The graphs consist of a red line graph showing average monthly temperature, and a simple column graph showing average monthly rainfall figures. Rainfall is, by tradition, shown in blue. Which of the FOUR climate zones are both Portland & Minneapolis?
ANSWER - Both Portland AND Minneapolis are considered TEMPERATE. Why?
Climate Activity Directions: Complete the Climate Activity Worksheet with a partner. You will need the Climate Activity Packet provided by your teacher to complete the questions. PLEASE DO NOT WRITE ON THE PACKET. Return the packet to the teacher at the end of class. If you do not finish you can access the Climate Activity packet on my School web site.
While you are working Please open your ISN to your isotherms on page 64 so they can be graded.
Exit Ticket What is the main unanswered question you leave class with today? Rate your understanding of today s lesson using the three boxes at the bottom.
Tropical (0-25 degrees latitude) Temperature = warm year round Precipitation = high levels of precipitation
Desert (Arid) (25-35 degrees latitude) Temperature = hot during the day Precipitation = low levels
Temperate (35-60 degrees latitude) Temperature = seasonal variation Precipitation = moderate to seasonal
Polar (60-90 degrees latitude) Temperature = cold year round Precipitation = low levels
Climate Change
El Nino (impact on global climate for 1-2 yrs) Dry conditions in the western Pacific (Australia & Indonesia) Heavy rainfall in South America (Peru) & Southern U.S. Mild winter temps in Northern U.S.
Volcanic Eruption (1-100s of yrs depending on size of eruption) Volcanic dust & sulfur dioxide blocks solar energy
Meteor Impact (similar to volcanic eruptions)
Global Warming (human impact on atmosphere, could be 100s of yrs)
Ice Ages (1000s of yrs)
Ice Age (from ocean current conveyor belt )
Continental Drift (millions of yrs)
