Spring 2007 homework
The critical thinking standards that will be used in grading Earth Science homework
assignments are clarity, accuracy, completeness, relevancy, significance, and logic.
Use maps provided; internet maps will not be accepted for credit.
Homework is to be submitted at the beginning of class on Tuesdays. It does not have to be typed.
Do not put it in your folder. Remember to put your name(s) on each sheet of paper. All NAMES MUST BE
IN THE UPPER RIGHT CORNER OF THE PAPER.
Any late work must be discussed with the grader; I will not accept any!
Homework 1. Using a world map, label all continents and oceans. Then add some smaller seas to bring the number to a total of 20 items. If this seems like busy work, then count yourself luck because many of your peers will need to look up this material in an atlas.
Homework 2. List the eight planets in order from Sun and give a unique fact about each one. Remember, their order from Sun has been given and the number of moons they have may not remain the same. Find other facts. Why is Pluto not considered a planet?
Homework 3. The Sun is the source of most energy that supports life. Give two specific examples of autotrophs. Give two specific examples of each type of heterotroph.
Homework 4. No group work is allowed for this homework unless you share a household; therefore, if you do group work, you will need to state that you share a household clearly at the top of your paper. You should have a 7 day water supply in case of an earthquake. That supply should consist of 4 liters (1 gallon) of water per person each day and the same amount of water for large pets and half that amount of water for small pets. Very small pets such as spiders and cockroaches will not need a separate supply of water. How much water do you need for your household? Where do you have enough room to store this amount of water?
Homework 5. Locate the plate boundaries on a world map using red for convergent boundaries, blue for divergent boundaries, and green for transform boundaries. You do not have to indicate the small transform faults that occur along the divergent boundaries.
Homework 6. Locate the following active or potentially active volcanoes on a world map: Ardoukoba, Auckland Field, Fuji san a.k.a Mount Fuji, Hekla, Kilauea, Mammoth Mountain, Mount Rainier, Popocatépetl, Redoubt, and Vesuvius. If you can’t find the volcano, you may use a town of the same name.
Homework 7. Use a world map to label 10 significant streams a.k.a rivers; show the main stream and its tributaries in blue. You will need to have at least one on each continent except Antarctica.
Homework 8. Use a world map and locate the continental glaciers of the world by coloring the ice masses blue. These are those huge glaciers that occupy a large area of land rather than small mountain valleys. Name any large populated area adjacent to the glaciers. If you are not sure of the populated areas, look up the world’s largest cities.
Homework 9. What is the source of your household water? You can get some of this info from your water company. Most have a web site. Many water sources may become polluted; how may this happen to your household water? The text book may help with this part of the assignment.
Homework 10. Using the net or other sources, determine the typical wave height in the Pacific and Atlantic Oceans. Then determine what a rouge wave is and how large they may become.
Homework 11. Using the net or other references, determine the maximum wind speed recorded that is not associated with tornadoes or hurricanes. Compare that with the local wind speed during any afternoon here in Southern California.
Homework 12. Using a world map, color all large deserts yellow. Be sure to label them with their name. You should have one on all continents; they are called dry valleys on Antarctica.
Homework 13. The troposphere cools at an average rate of 6.50 C for every kilometer you travel above sea level. Mount Everest is approximately 8.8 kilometers high. On a hot day with a sea level temperature of 400 C (1040 F), what is the temperature at the top of the mountain? Remember that the number on the top of the mountain will be lower than the sea level temperature.
Homework 14. Winds cause the gyres. Put the ocean currents on the map using red for warm currents and blue for cold currents. Just use the large currents. Then add the wind involved with the currents; use green for the wind.
Homework 15. Many of the world’s fish are economically extinct or are likely to contain large amounts of Hg or other toxins. Using the web site: www.seafoodwatch.org, determine ten safe or best choices and ten items to avoid.
