Convection Currents and Weather

What mainly contributes to the direction of wind’s actual path?

• revolution of the Moon around Earth

• rotation of Earth on its axis

• gravitational pull on the gases in the atmosphere by the Sun

• number of severe storms in the atmosphere due to Earth’s global temperature

A student covers the mouth of a plastic bottle with a balloon and fills two bowls, one with hot water and the other with ice. The student holds the bottle in each bowl and observes the effect that each temperature has on the balloon. Which question is the demonstration most likely designed to answer?

• How does water evaporate to begin the water cycle?

• Is water more dense than ice?

• How does temperature affect global convection currents?

• Does air experience a phase change when heated and cooled?

• Temperature and pressure

• Mass and density

The main reason that we have currents in the ocean and air is

• the sun heats the air and ocean evenly everywhere

• the heat inside the earth heats the ocean and the ocean heats the air

• the sun cannot heat both the air and water, so one must heat the other

• the sun heats air and water more at the equator because it receives more direct sunlight
