Energy and water in the atmosphere

Why is the atmosphere heated unequally by the sun?

• The mesosphere is thicker by the poles, absorbing more heat making it colder

• Some areas are heated by the sun more directly due to earth's tilt

• Convection currents

Colin knows that the water cycle follows certain steps in a repeating cycle. When the sun heats water molecules, they increase speed and collide. On Sunday he noticed that a puddle on the sidewalk was getting smaller over time. Which step in the water cycle would Colin predict is occurring?

• Transpiration

• Collection

• Evaporation

• Condensation

On a wind less hot day, one would perspire more in a thick forest because

• heat is created by respiration of plants

• comparatively less light falls in the forest

• plants transpire

What is respiration?

• Animals evaporate water from the surface of their skin

• Animals release water vapor into the air when they breathe out (exhale)

• Animals breathe in (inhale) Carbon Dioxide

what is one condition for condensation to occur?

• There must be high air pressure

• Low density air

• tiny particles must be present so water has a surface to attach to

The dew point is.....

• the temperature at which condensation begins.

• the volume of air

• the pressure at which cold air rises

• the dew point

• humidity

How are the two temperature measurements used in a sling psychrometer?

• Wetter air cannot absorb as much water from the bulb, so the temperature doesn't change as much, higher humidity

• Wetter air can absorb as much water from the bulb, so the temperature doesn't change as much, less humidity

• Wetter air cannot absorb as much water from the bulb, so the temperature doesn't change as much, lower humidity

The ability of air to hold water vapor depends on ____________ because _________________

• Temperature, cool air can hold more water than cool air

• Temperature, warm air can hold more water than cool air

Suppose the 2 thermometers in a sling psychrometer show almost identical readings, was the measurement taken in Florida or the Arizona desert?

• Florida

• Arizona desert
