A water strider can skate along the top of a pond because:

• covalent bonds result in water cohesion (surface tension)

• hydrogen bonds result in water cohesion (surface tension)

• water striders have adapted to take advantage of water cohesion

• water striders are afraid of water and avoid it

Multiple Choice

What is adhesion in the context of water molecules?

• The ability of water to stick to itself

• The ability of water to evaporate

• The ability of water to freeze

Multiple Choice

Refer to the picture of water sticking to a leaf; this is occurring because of:

• capillary action, cohesion and adhesion

Multiple Choice

What is capillary action and how does it relate to plants and towels?

• It is how plants absorb nutrients

• It is how towels dry quickly
