What makes the water molecules different from any other substance on Earth? Also represented by the dotted lines on the image.

• Ionic bonds

• Covalent bonds

• Strong bonds

• Hydrogen bonds

Why does ice float?

• As water freezes, it expands and its density decreases.

• As water freezes, it takes up more hydrogen from the atmosphere, causing it to have a greater buoyancy.

• As water freezes, air becomes trapped between the hydrogen bonds of water molecules.

• As water freezes, it takes up more oxygen from the atmosphere, causing it to have a greater buoyancy.

Large bodies of water, such as lakes and oceans, do not quickly fluctuate in temperature. What is the reason for this phenomenon?

• Water is an acid.

• Water is a versatile solvent.

• Water has a high heat capacity.

• Water acts as a buffer.

Large bodies of water help to keep nearby climates from being too hot or too cold  because they...

• absorb heat in the spring and slowly release that heat in the fall
• absorb heat in the fall and slowly release that heat in the spring
• absorb heat in the summer and slowly release that heat in the winter
• absorb heat in the winter and slowly release that heat in the summer
