Making a water cycle model 1. add soil to a plastic cup. 2. place an ice cube on the soil. 3. use plastic wrap to seal the top of the cup. 4. place the cup in a location with direct sunlight. which statement is the best comparison between earth’s water cycle and the model described? a) the water evaporates down into the model’s soil, instead of into the air. b) the ice cube in the model represents condensation in earth’s water cycle. c) when the ice melts, it will model infiltration as it absorbs into the soil. d) condensation occurs in the model’s soil, like it occurs in clouds for earth.

Certain bacteria (such as aquaspirillum magnetotacticum) tend to swim toward the earth’s geographic north pole because they contain tiny particles, called magnetosomes, that are sensitive to a magnetic field. if a transmission line carrying 100 a is laid underwater, at what range of distances would the magnetic field from this line be great enough to interfere with the migration of these bacteria? (assume that a field less than 5% of the earth’s field would have little effect on the bacteria. take the earth’s field to be 5.0 * 10-5 t, and ignore the effects of the seawater.)
