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.

The tightness across the surface of water that enables paper clips to float is ____________.

• adhesion

• capillary action

• surface tension

  (cohesion)

• polarity

Transpiration is

• the movement of water through a plant from the roots up the stem
• the loss of water from the leaves of a plant by the process of evaporation
• the flow of water into plant roots by osmosis from the soil
• the process of minerals and sugars moving through plant veins
