1.Below is a short description of why the earth has seasons. There are 5 content mistakes. Find these content mistakes and correct these mistakes by deleting the mistaken word and inputting the correct word (in CAPITALS) within the text of the description. Description: There are five reasons why the earth has seasons. The first reason is revolution. The earth revolves around the moon every 365.24 days. Without this revolution, the earth would be in only one perpetual season. The second reason for the seasons is rotation. The earth rotates on its axis every 24 hours. Without this rotation there would be no Circle of Illumination and the entire earth would be in total darkness, 24 hours a day, 365.24 days a year. The third reason for the seasons is the tilt of the earth. The earth is tilted on its axis twenty-two degrees. This tilt is what causes direct sun angles to migrate from the Tropic of Cancer to the Tropic of Capricorn. The fourth reason for the seasons is axial parallelism. Axial Parallelism says that the earth never stays at its regular tilt. The last reason for the seasons is the sphericity of the earth. Because the earth is a sphere, the equator receives 2.5 times more sun energy than the poles. This sphericity causes an even receipt of insolation across the surface of the earth.
2. Look at the image below. In the essay box provided, write down each letter (A, B, C, D) and describe the season that letters image of the earth represents. You need to include each of the following in your description: 1. Name of the season 2. Date the season occurs
3. Declination of the sun 4. Hours of darkness and light (24 hours dark/light Antarctic Circle, 24 hours dark/light Arctic Circle and 12 hours dark/light everywhere) P.S. Be careful on this one. Make sure you fully understand the seasons before you try to do this.
You are flying into Los Angeles and notice a brown layer of air encircling the city. What is the term for this brown layer of air and what causes this brown layer of air to form?
4. What is the term given to rain that has abnormally high pH values? How does this rain with high pH values form? Click on the link of the map that shows pH values in the U.S. Where are pH values the highest? Why are pH values so high in this region of the U.S.?
5. Explain what we are seeing in the image below and why it is occurring.
6. Why are sunsets and sunrises red, orange and pink?
7. What is the greenhouse effect? Make sure you include the following in your explanation: the wavelengths of energy the sun emits, the wavelengths of energy the earth emits, and whether the earth's atmosphere is transparent to these wavelengths of energy. Why is the greenhouse effect important to life on earth? The greenhouse effect is often spoken of in terms of global warming and climate change. Just knowing how the earth heats and the gases involved, what would happen if greenhouse gases were to increase in the earth's atmosphere?
8. You and a friend decide to pick up, fly out to Colorado, and ski for a couple of days. Your friend doesn't ski much and is wondering what to bring. You tell him/her that he/she should bring sunglasses and he/she laughs at you. Wearing sunglasses and skiing does seem a little silly, after all. Use what you have learned in this class to write an explanation to your friend why he/she would want to wear sunglasses while skiing (especially if you happen to have bright and sunny days).
9. Explain why the warmest time of day occurs 2-3 hours AFTER the earth receives its maximum amount of insolation
10. What is the urban heat island effect and what causes it?
11. There are four main things that control temperature on the planet. List and briefly describe these four things.
12. Why does land heat and cool faster than water? Make sure you fully explain these
13. What causes wind. Make sure you list each reason, but just briefly explain them in your answer.
14. Click on the image below and answer the following questions. 1. What kind of pressure system is shown in this image? 2. In what hemisphere is this pressure system located? 3. What three forces are working to create this pressure system (do not include gravity on this one). Make sure you describe how these forces are working to create this system. 4. What kind of weather would we expect with this system?
15.Describe earth's atmospheric circulation model, starting from the equator and moving towards the poles. Make sure you include the high/low pressure cells, the winds and how they diverge/converge to create the pressure cells, and other important features contained within each cell.
16. You are walking along a beach in California and feel a cool breeze coming off of the ocean. What is this breeze called and how does it form (make sure you include whether it forms during the day or at night).
17. Using India as your example, explain what a monsoon is by describing wind changes, pressure changes, and the changes that these bring about in terms of precipitation patterns.
