NSCAS Review

Which statement BEST explains Jayson’s observations?

• Aluminum foil is a good conductor of thermal energy.

• The layers of aluminum foil absorbed heat instead of transferring it.

• Layers of air between the foil wrappings reduced the transfer of heat.

• The warmer atmosphere around the foil-wrapped beaker prevented the transfer of thermal energy.

A student is studying the rings on a tree stump. Each ring represents a year of growth. One ring on the stump is much thicker than the others. The MOST likely explanation for this thick ring is that there was

• more predators causing less growth of the tree.

• more pollution causing less growth of the tree.

• more rainfall allowing for more growth of the tree.

• more sunlight allowing for more growth of the tree.

The graph shows water table levels in an aquifer changing over a period of time.

Which MOST likely caused the changes observed in the data over time?

• increase in the amount of precipitation

• increase in water conservation efforts

• decrease in the amount of recharge

• decrease in irrigation for farming

What is one benefit to the company of placing the well where they did instead of making the well shallower?

• Drought should have less of an effect on the amount of water produced by the well.

• Confining beds will prevent more water from entering the aquifer near the well.

• Water in the aquifer where the well is located will recharge more quickly.

• A deeper well will be much less expensive to drill than a shallower well.
