1. Chapter 7 Lesson 1 Climate
SPI’s: Math: 6.4.7

2. In this lesson we will learn some of the factors that affect climate.
Main Idea
In this lesson we will learn some of the factors that affect climate.

3. At the end of this lesson…
You will be able to describe two ways in which bodies of water can affect climate, using the words “ land breeze”, “sea breeze”, and “ocean currents”.

4. Let’s get this party started!!!

5. Vocabulary
Climate
Ocean current
El Nino

6. Climate: normal pattern of weather in an area over many years.
Science Journals
Climate: normal pattern of weather in an area over many years.

7. Ocean current: moving stream of water created by winds pushing against the ocean’s surface.

8. El Nino: periodic change in direction of warm currents in the Pacific Ocean.

9. Let’s read about Uneven Heating and Major Climate Zones on PP
Let’s read about Uneven Heating and Major Climate Zones on PP. 246 and 247
Remember, when we read we use fluency and expression. We also pay attention to punctuation.

10. Name Earth’s 3 major climate zones.
Challenge
Name Earth’s 3 major climate zones.

11. Answer
Polar Tropical Tropical
Temperate

12. Critical Thinking
In temperate zones, when do the sun’s rays strike Earth at more direct angles?
Summer?
Winter?
Explain

13. Critical Thinking answer…
The summer months are warm in temperate zones. This means the sun’s rays must be striking at more direct angles during the summer months.

14. Cause and Effect
What is the effect of the sun’s rays striking an area at angles less than 90 degrees?

15. Cause and Effect answer…
Cooler Temperatures!!!

16. Land and Sea Breezes
Take a look at the pictures and captions on P.248. See if you can find out why land breezes occur at night?

17. And the Answer is…
At night, land cools down faster than water. The cool air over the land moves out over the water as the warm air over the sea rises.

18. Mountain Effect
Why are some places rainier than others? Let’s RTFO (Read to Find out) on P. 249.

19. Windward and Leeward side
Describe the difference in precipitation (rain and snow) on the leeward side and windward side of a mountain.

20. Windward and Leeward side
Windward side = Very wet Leeward side = Very dry

21. Who remembers what we’re learning in this lesson?

22. Who remembers what we’re learning in this lesson?
To describe two ways in which bodies of water can affect climate, using the words “ land breeze”, “sea breeze”, and “ocean currents”.

23. Show me how smart you are…
Why do more rain and snow fall at the top of a mountain than at its base?

24. Show me how smart you are…
The air is cooler at the top of a mountain. The air needs to be cool to form clouds that drop precipitation. (Rain or snow)

25. Show me how smart you are…
So is the air warmer or cooler at the base of a mountain?

26. Show me how smart you are…
Warmer!!!

27. Ocean currents move water and energy from place to place.
Oceans and Climate
Ocean currents move water and energy from place to place.

28. Oceans and Climate
How many of you have ever been to the lake and noticed the water moving?

29. Oceans and Climate
That movement is similar to an ocean current. “Wind pushing against the ocean’s surface causes moving streams of water called ocean currents.”

30. Oceans and Climate
Let’s read about ocean currents on P. 250 Is it hot or cold near the equator?

31. Oceans and Climate
Hot!!!

32. Name some factors that affect climate.
Review
Name some factors that affect climate.

33. Review
Mountains
Bodies of water
Earth’s overall shape and tilt

34. What are ocean currents, and what sets them in motion?
Review
What are ocean currents, and what sets them in motion?

35. Review
Ocean currents are moving streams of water caused by winds blowing on the ocean’s surface.

36. Review (Cause and Effect)
Describe two ways in which bodies of water can affect climate. Use these words in your answer: land breeze, sea breeze, and ocean currents.

37. Review (Critical Thinking)
Study the illustration on PP. 246 and 247.What kind of climate do you think Miami, FL has? Explain.

38. Review (Cause and Effect)
What factors help to account for the differences among tropical, temperate, and polar climates?

39. Way to Go!!!
