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

Wind and water transport rain and the suns heat around the Earth to create different climates.

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

Weather is the changes in the air that happens over a small period in time in an area that you can not predict. Climate, however, is a predictable sequence of continous weather in a certain area over a long span of time.

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

Because wind flows counterclockwise around low pressure areas, winds above North America usually blow from West to East.

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

The Northeasterly trade winds were the winds that European sailors used to get to South America and the islands north of it.

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.

The tilt of the Earth affects climate because the tilt of the Earth is the reason for seasons! The Earth is tilted on its axis, and it travels in a loop around the sun each year. The four different seasons in the year resemble different climates, and these will change throughout the year depending on the tilt of the Earth and where it is near the sun.

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

This relates to the Voyages of Columbus because the Northeasternly tradewinds are what brought Columbus to the Carribean. On his trip to so-called "Asia" when Columbus had no wind, he was most likely around the 30 degrees North, where there is little to no wind.
