The water cycle consists of some water evaporating from the surfaces of bodies of water and going into the air. as result of air temperatures, water vapor eventually condenses and falls as rain. the rain nurtures life and the environment and eventually makes its way back into water where the cycle is repeated. water has an unusually low vapor pressure and does not rapidly evaporate because of its a) neutral ph. b) liquid form. c) hydrogen bonding. d) non-polar structure.

Darrel conducted an experiment with the following procedure: fill two cups with ice water. place an uninflated balloon snuggly onto your left index finger. blow a little air into an identical balloon, and place it onto your right index finger. place both fingers into the cups of ice water. darrel noticed that his right finger felt warmer in the ice water than did his left finger. which of the following does the experiment show? a. air is a good radiator of heat. b. air is a good insulator of heat. c. air is a good conductor of heat. d. air is a good convector of heat.

African penguins, which inhabit the coasts of southern africa, were classified as an endangered species in 2010. two significant threats to their survival are ecosystem damage from oil spills and overfishing by humans. overfishing depletes the food supply of african penguins. the best method to reduce the threat of overfishing would be to . the risk of oil spills could be reduced by increasing the use of , which should oil consumption. if an oil spill does occur, could be used to remove the oil so the ecosystem may more quickly recover.
