Two climates have distinct alternating wet and dry seasons. Name them, and mention the time of year when each has its wet season, then explain the cause (the specific weather elements) for the wet season in each

(Please be as thorough as possible)

Rocks collected on the coast of northern Greenland, at a latitude of 76.5 degrees North are brought into the paleomagnetic lab for study. You collect a number of samples and find that the magnetic field preserved within them varies slightly, but that the group has an average inclination of -75 degrees and a declination of 135 degrees. Geochemical dating show that all the rocks are 60 My old.

2) describe how these rocks have moved since forming (Be as specific as possible) and determine at what speed must these rocks have traveled since their formation? is this a minimum or maximum estimate of their velocity?

Silica nanoparticles are synthesized through the sol-gel method. The size of the nanoparticles is controlled by the amount of water. Why is the size of nanoparticles controlled by the amount of water?

Write an explanation using at least one piece of evidence about the Earth's interior to explain cycling of matter by thermal convection and how it relates to plate tectonics (movement of plates, earthquakes and volcanoes)

Discuss briefly how both sedimentary and igneous rocks form and discuss the likely sources of the magma that resulted in igneous rocks in Connecticut’s Central Valley.

In your opinion, discuss your long term predictions for the planet. Sum up the major planet-altering events that will arise from human-caused climate change.

What are the impacts in terms of physical damage, chemical contamination, and climate aftereffects?

Assume grooved brain coral requires sunlight, a high concentration of zooplankton (tiny floating organisms) in the water every evening, an open, solid place to attach that is close (not more than 3 meters underwater) to the surface, water temperature between 65 and 85 degrees F, and a water pH between 8.1 and 8.4. Aside from its early life as a tiny larva seeking an attachment site, coral has a sedentary lifestyle. During the day, its photosynthetic symbionts produce sugars and other nutritious chemicals; at night the coral polyps uncurl their tentacles and capture plankton out of the water. Which of the following is the best and most complete list of the resources, rather than the conditions, that the coral species requires?

A. Sunlight and a high concentration of zooplankton.

B. Sunlight, a high concentration of zooplankton, a solid spot close to surface where the coral can attach, water temperature between 65 and 85 degrees F, and a water pH between 8.1 and 8.4

C. Sunlight, a high concentration of zooplankton, and a solid spot close to surface where the coral can attach.

D. Water temperature 65 - 85 degrees F, and a water pH 8.1 - 8.4.

An aerial camera has a 9½-inch square film format and a 6-inch focal length lens. What must the flying height (in meter) be to obtain a scale of 1/2000? (Hint: 1 inch=2.54 cm)

1. Describe the contribution of John Snow to epidemiology. What type of study did he conduct? Was it analytical or descriptive epidemiology (or both)? Be specific with examples from his study

2. The total energy consumption of Hong Kong in year 2008 was 285,430 TJ. Assume the daily rate of solar energy received in Hong Kong is 10 kWh/m2 and that a solar PV panel has an efficiency of 10% in converting sunlight to electricity.
(a) Calculate the land area that is required for solar panels if Hong Kong uses sunlight as its only energy source to support the year 2008 energy consumption. (4 points)
(b) Compare against the total land area in Hong Kong, what percentage of land will the solar panels take up? (2 points)
(c) Even during the night we still need electricity and given that we can only rely on solar energy, what can Hong Kong do to ensure electricity made from solar energy is available 24 hours a day (i.e. both during the day and night)? Explain your answer. (8 points)
