A student takes a bottle of cold water from the refrigerator and leaves it on the counter. Ten minutes later, the student noticed there is now water on the outside of the bottle. What scientific phenomenon explains the water on the outside of the bottle?

• condensation occurred because the temperature of the air nearest the bottle increased causing water droplets to form.

• condensation occurred because the temperature of the air nearest the bottle decreased causing water droplets to form.

• Evaporation occurred because the temperature of the air nearest the bottle increased causing water droplets to form.

• Evaporation occurred because the temperature of the air nearest the bottle decreased causing water droplets to form.

What is happening to the total amount of water on Earth?

• The amount of water on Earth is increasing because of precipitation

• The amount of water on Earth is constantly changing due to the weather

• The amount of water on Earth is decreasing because water is consumed and evaporated

• The amount of water on Earth stays fairly constant because what is evaporated comes back as precipitation

What process in the water cycle involves forming clouds?

• Evaporation because as water vapor gains energy it changed from a gas to a liquid

• Evaporation because as water vapor loses energy it changed from a gas to a liquid

• condensation because as water vapor gains energy it changed from a gas to a liquid

• Condensation because as water vapor loses energy it changed from a gas to a liquid

Which statement best describes how density is affected by salinity?

• As the salinity of the water decreases, the density increases

• As the salinity of the water increases, the density increases

• As the salinity of the water decreases, there is no change in density

• There is no relationship between salinity and density

How do great rivers such as the Nile, the Amazon, and the Mississippi affect the salinity of the oceans they flow into?

• The rivers increase the salinity of the oceans because they remove fresh water

• The rivers decrease the salinity of the oceans because they remove fresh water

• The rivers increase the salinity of the oceans because they add fresh water

• The rivers decrease the salinity of the oceans because they add fresh water

• Temperatures decrease while density increases

• Temperatures increase while density increases

• Temperatures decrease while the density decreases

Which statement best describes why warm ocean currents are usually surface currents?

• warm water is less dense than cold water

• ocean tides bring warm water to the surface

• warm water contains more salt than cold water

• ocean water loses heat to the air at the surface

• undertow

• upwelling

Which of the following is the BEST explanation for why oceans have two different types of currents?

• Surface currents are caused by changes in density whereas deep currents are caused by wind

• Surface currents are caused by wind whereas deep currents are caused by differences in density

• Surface currents are caused by temperature differences whereas deep currents are caused by changes in salinity

• Surface currents are caused by changes in salinity whereas deep currents are caused by changes in temperature
