What are the three processes that causes tectonic plates to move?

examine the Gaia hypothesis. In your post, discuss the merits and the pitfalls of this hypothesis. Using your knowledge of Earth science, does the hypothesis have merit or not?

Also, comment on whether you think the Earth and its spheres actually change over time. Be sure to briefly summarize the systems and spheres.

Scenario:

In April a friend stops by to visit. The conversation turns to gardening, and your friend tells you he tried to get an early start on his vegetable garden by starting seeds inside his house back in February. He reports to you that he has had little success. Only a few seeds had sprouted, but many did not. The seeds that did germinate, with a couple of exceptions, did very poorly.

Most of the seeds he planted were from seed packets he bought from the garden center. Some seeds he saved from the previous year’s garden. He planted them in plastic cups with no drain holes (to retain water he says), and placed them in his kitchen window which is on the North side of the house.

What advice and suggestions would you provide to your friend for next year’s attempt?

1. Would Santa Clarita (latitude 34^oN) ever receive direct, vertically overhead rays of the sun? Why or why not?

2. Why does the Equator get 12 hours of day and 12 hours of night, every day of the year, and all other latitudes do not?

3. On the June solstice, why does the area between the Arctic Circle (66.5^oN) and North Pole (90^oN) have 24-hour daytime, whereas the area between the Antarctic Circle (66.5^oS) and South Pole (90^oS) gets 24-hour nighttime?

4. Would Istanbul, Turkey (41^oN) ever get 12 hours of night in July? Give at least 2 accurate reasons for your answer.

5. Define aphelion and perihelion What are their dates? Why don’t they have any effect on our seasons?
