What property of water causes it to “stick to itself” and form droplets?

• universal solvent

• polarity

• specific heat

• expands when it freezes

What property of water explains why the oceans are salty?

• universal solvent

• polarity

• specific heat

• expands when it freezes

How are bugs and some lizards able to stay on the surface of the water?

• Surface tension

• Cohesion

• Adhesion

• Water wicking

 What does it mean If the molecule is polar?

• The molecule it at earth’s poles

• The molecule has a positive and negative region

• The molecule is very cold

• The molecule divides people

Why does water take so long to boil?

• It has a high specific heat capacity

• It is a really dense material

• You are watching it

• It starts out frozen and has to melt

Which of the following is not a reason that we cannot use glaciers and ice caps as a source of fresh water?

• It’s frozen

• Its in remote areas

• It contains dissolved minerals

• It would take a lot of energy to melt

When water runs through limestone, caves are sometimes formed. If water drips slowly in the same place inside one of these caves, what would occur?

• Stalagmites and stalactites will not form in this area because they require fast-moving water to form.

• Stalactites and stalagmites will break off in the cave because the water will weather and erode them away.

• Stalactites will form connected to the ceiling, and stalagmites will form connected to the floor because the minerals will be deposited in the cave.

• Stalagmites will form connected to the ceiling, and stalactites will form connected to the floor because the minerals will be deposited in the cave.
