1. If only density increases with increasing depth within the Earth, the velocity of a P wave should ___________. stay the same increase decrease 2. If a P wave were to go from a solid to a liquid - what would happen to its velocity? stay the same increase decrease to 0.0 decrease 3.If an S wave were to go from a solid to a liquid - what would happen to its velocity? stay the same increase decrease to 0.0 decrease 4. With increasing travel time the difference in arrival times between the P and the S waves _________ increases decreases stays constant none of the above

October 4: Which is the correct penny? NOTE: You cannot look at a real penny!

A student decided to set up an experiment to see if cats preferred skim milk or 2% milk. She put out a cup of milk for 5 kittens and then measured how much the kittens drank over the course of a day. The same kittens were used and the milk was served at the same temperature. The student discovered that the cats liked the 2% milk more than the skim milk. What is wrong with the above experiment? A. There is no independent variable. B. The milk should be served at different temperatures C. There are no constants present. D. Repeated experimentation is needed.

Ozone layer is located in the : Mesosphere. Lower stratosphere. Thermosphere. 4. Ozone layer does not influence the life on Earth in any way. True. False. 5. Excessive exposure to ultraviolet radiation can cause skin cancer. True. False.

1. Although we cannot see air pressure we know it exists because It is measured on a thermometer We feel it when air presses against us It is measured on a hygrometer 2.
