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

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

• covalent bonds result in water cohesion
• hydrogen bonds result in water cohesion (surface tension)
• water striders have adapted to take advantage of water cohesion
• low surface tension of water
