Questions and answers about Global Winds, Climate and the path of Hadley Cells

1. Write down the main idea of the chapter "Climate" here.

Wind and water carry rainfall and the sun's warmth around the world to create different climates.

2. Reading Check Questions on 54- What is the difference between weather and climate?

Weather is the current temperature or the state of the atmosphere at a specific time, climate is the average temperature or the usual weather that happens in an area over a longer period of time.

3. Applying Map Skills Question 1. In which general direction does the wind blow over North America?

The wind over North America tends to be a westerly wind. Which is a wind that generally blows west.

4. Applying Map Skills Question 2. What winds did European sailers use to get to South America and the islands north of it?

They used the Northeasterly trade winds.

5. Answer the Reading Check Question on page 55- How does the tilt of the Earth affect climate? (This is a difficult, tricky, complicated question. You can NOT just copy the answer out of the textbook. Because the answer is NOT EXACTLY found in the textbook. You will have to figure it out, think about the notes we took and discussed, and ... re-read page 55 to answer this well.

Depending on a place's positioning on Earth the amount of sunlight it gets at different times of the year can vary. Sunlight plays a direct role in the temperature of any location on Earth, and, if you change the average temperature of a place then the overall climate will change as well.

6. How does this relate to the Voyages of Columbus? Answer, and put in a link to YOUR Columbus Wind Project.

It relates because you can see the wind patterns changing as Columbus sails between latitude lines. For example there was a period of about nine days when Columbus had so little wind that he barely moved at all, this happened to be around the same time that he was crossing the 30 degree line. To go back home Columbus used the winds above the equator to push the ship back up in the direction of Spain.
