Glaciers are large sheets of ice found in areas where the air temperature remains cold most of the year. Students use a computer model to study how glaciers can affect land and living things. The students also study data that show that glaciers are melting rapidly.
Which changes to the computer model should the students make to show the most likely effect of melting glaciers?
A Make the oceans more salty.
B Cover some coastal lands with water.
C Decrease the amount of water in the atmosphere
D Move animals living at the poles closer to the equator.
Cover some coastal lands with water.

C Most of the freshwater on Earth is available for humans to use.
D All the freshwater on Earth is available for humans to use.
Only a small amount of freshwater on Earth is available for humans to use.

Why is the side of a mountain nearest the ocean usually lush and green?
A Interaction between the ocean, air, and mountain causes rainfall on that side.
B Rising air warms that side of the mountain.
C Rain falls after clouds pass the mountain peak.
D Plants cause the mountain to form a rain shadow.

B A little more than thirty (30) cans
C About two and a half (2½) cans
D Less than half ( ½ ) a can
About two and a half (2½) cans
