1. Write down the main idea of the chapter "Climate".
Climate and weather are two different things, although similar, and climate depends on where you live.
2. What is the difference between weather and climate?
Climate is referring to the average year-round or seasonal temperatures or whether. Such as, if it was in a country where is the summers it was hot and dry and in the winter it was cold and rainy. Weather is referring to a short period of time where the environment is in a certain state, such as rain or snow or sun.
3. Before you forget about the Hadley Cells (the moving air cells around our planet), look at the "Applying Map Skills" diagram and questions found on page 55. Doesn't it look familiar? Yes or No. Circle the Correct Answer.
Yes.
5. Applying Map Skills Question 1. In which general direction does the wind blow over North America?
It generally blows east.
6. Applying Map Skills Question 2. What winds did European sailors use to get to South America and the islands north of it?
They used the “Northeasterly Trade Winds”. And Columbus's voyages were greatly related to this. AS he headed across the atlantic ocean, he was inbetween the thirty and sixty degrees south, so the winds were greatly in his favor. Then heading back, for the first few days to winds were fantastic, because of where he was on earth, but then for about 9-10 days Columbus and his crew were stuck at around 30 degrees north wear there is barely any wind. But eventually they made it up to inbetween sixty and thirty deggrees north and were on thier way smooth and steady.
7. Read pages 54 and 55.
8. 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 the climate because of indirect and direct sunlight rays. The equator region is always hot because of direct sunlight rays which are always hitting the earth and warming the region up. But, in places where the sun’s rays do not hit directly, the climate can be cold and warm. Such as the state of New Hampshire. As the earth rotates, it spins like a top, tilting itself around every revolution around the sun, or a year. As the earth tilts in this way, the amount of sunlight we get varies, which is what creates seasons. When the earth is tilted downward, we are having summer, while the people in the southern hemisphere are having winter because they are tipped away from the sun. So if you live in the equator, where it is always bright and warm, then that is what your climate is like. But if you live up north or down south you have mixed climates depending on the season. That is how the earth’s tilt affects climate.
