Question 1 of 9 (worth 2.5 points) The Earth is continuously bathed in solar radiation. On average, the Earth receives 345 W/m2 of solar radiation at the outer edge of the atmosphere. This quantity is called the "solar constant". However, the actual quantity that reaches the Earth's surface varies from place to place and day to day because of the orientation of the Earth with respect to the Sun and the spherical geometry of the Earth and its atmosphere. Insolation at the Earth's surface is the amount of radiant energy from the Sun that makes it through the Earth's atmosphere and impacts upon a unit surface area of the Earth over a given period of time. The amount of insolation received at the surface depends on a few variables, including 1) the zenith angle, 2) length of day, 3) path length through the atmosphere, and 4) atmospheric conditions (clear, foggy, hazy, cloudy, etc). Seasonal and daily temperature changes are largely controlled by changes in insolation. In the lectures, we discussed how to calculate zenith angle, which determines intensity of solar radiation reaching the top of Earth's atmosphere. Think about: Why is zenith angle so important, and why are we studying zenith angle in physical geography? Which of the following locations (at the TOP of the atmosphere) would show the greatest range in insolation between summer and winter? A. Singapore B. Sochi, Russa C. Berlin, Germany D. Saint Petersburg, Russia E. Barcelona, Spain F. Athens, Greece G. Soufrière Hills, Montserrat H. Kabul, Afghanistan I. Monrovia, Liberia Question 2 of 9 (worth 2.5 points) Please select TWO answers, one for each question. Suppose that you and Captain Jack Sparrow are planning to dock in Port Royal in Jamaica (18N) on June 7th, 1692. Scouts have alerted you that there is a low pressure system west of the island. What direction is the wind blowing in Port Royal, Jamaica? Wind directions are named for the direction from which they blow. A few minutesminutes before noon, a devestating earthquake destroys much of the city (you and Captain Sparrow narrowly escape with your lives). What is most likely the cause of this earthquake? A. Wind: North B. Wind: South C. Wind: Southeast D. Wind: West E. Wind: East F. Earthquake reason: The North American Plate being subducted under the Cuba Plate G. Earthquake reason: Undersea mountains from ocean floor spreading H. Earthquake reason: A transform fault along the Caribbean Plate I. Earthquake reason: The Kraken Question 3 of 9 (worth 2.5 points) Imagine that you are sailing across the Pacific from New Zealand (45S) to Hawaii (20N) with Captain James Cook. On December 21 when you take a sighting on the Sun (at noon) and calculate that the Sun is at an elevation angle of 49.5 degrees above the horizon. What is your latitude? Enter as a whole number, two digits, XX, plus either N or S for hemisphere (e.g. 03N, 28S, 53N). You must follow this pattern, no hand-grading will be done. Question 4 of 9 (worth 2.5 points) What two factors, both resulting from the earth's tilt, are most important in contributing to the seasons? Together, these two factors determine the total amount of solar radiation incident on the top of Earth's atmosphere. Please choose the TWO correct answers. You must get BOTH correct to score points - no partial credit. A. changes to length of day (sunlight hours) B. changes in zenith angles C. differences between perihelion/aphelion D. hemisphere is relatively physically closer to sun Question 5 of 9 (worth 2.5 points) You are setting up a solar observatory at a research station directly on the Equator. You are in charge of the installation of a large swiveling solar dish antennae that must be pointed at the noontime position of the Sun for the entire year. The dish cannot turn around, but rather hinges from one side to the other side. See picture below: What is the total degree arc that this antennae must accommodate? A. 47 degrees B. 23.5 degrees C. 0 degrees D. 70.5 degrees E. 12.5 degrees F. 70 degrees G. 35 degrees Question 6 of 9 (worth 2.5 points) What is the tilt of the Earth at the Equator? A. 47 degrees B. 30 degrees C. 98.6 degrees D. 66.5 degrees E. 0 degrees F 23.5 degrees Question 7 of 9 (worth 2.5 points) Suppose you and Lord Cutler Beckett are assembling an armada to eradicate piracy in the Caribbean. After having left Europe, somewhere in the Atlantic you note on June 21st, 1686 that the sun is 81.7 degrees above the horizon (at noon). What is your latitude? Assuming your compass was not Jack Sparrow's magical compass, would it give a reasonably accurate reading at this latitude and why? Please select two answers; one for each question. A. 31.8N B. 58.2N C. 15.2N D. 34.7N E. 8.3N F. The compass would be accurate because compasses are accurate all over the globe G. The compass would not be accurate because you would be in the Bermuda Triangle H. The compass would not be accurate because iron deposits in Earth's middle core would interfere with the compass needle I. Davy Jones' Locker J. The compass would be accurate only if the ship were facing due west. K. The compass would be accurate because it is not near the higher latitudes L. The ships would be beached on the island of Hispanola Question 8 of 9 (worth 2.5 points) Please watch the following video and then answer the questions below. http://www.youtube.com/watch?v=ryrXAGY1dmE Two examples regarding processes in the Earth's crust were depicted in the video. First, what were they? Secondly, please select one appropriate example for each of these processes. You will pick TWO "Process options", and TWO "Example options". Incorrect answers will count against the score. A. Process option: Seafloor spreading/divergent plate boundary B. Process option: Transform fault C. Process option: Earthquake D. Process option: Subduction zone E. Example option: Mid-Atlantic Ridge F. Example option: Juan de Fuca Plate and North American Plate Boundary (Cascadia) G. Example option: Hawaii H. Example option: Himalayas Question 9 of 9 (worth 2.5 points) This is a TWO part question. Part 1) In lecture 25, Dr. Waylen talks about tides. Supposed you've been hired by National Geographic to assist a team of underwater film makers produce a documentary on coral reefs. You know that corals typically spawn during neap tides, and this would be a great event for the film makers to record. You would need to arrange a SCUBA trip to coral reefs at which time (please pick the correct letter)? Part II) What is the NAME of the tide indicated by C? A. Letter A B. Letter B C. Letter C D. Letter D E. Letter: None of these are correct. F. Name of C: Neap high tide G. Name of C: Neap low tide H. Name of C: Solar high tide I. Name of C: Solar low tide J. Name of C: Celestial high tide K. Name of C: Celestial low tide L. Name of C: Spring high tide M. Name of C: Spring low tide N. Name of C: Tide laundry detergent
