Which statement is true?

• Air is less dense at higher altitudes than at lower altitudes.

• Density depends on the size of particles that are in a given volume.

• Atmospheric pressure is higher at higher altitudes and lower in lower altitudes.

• There are less particles in the same volume of air at sea level than at mountaintop.

There is a ______________ relationship between altitude and atmospheric pressure.

• absent

• cause-and-effect

• contradictory

• balanced

Torricelli's tube of mercury was the first barometer, a tool that is used to measure

• humidity.

• rainfall.

• wind speed

Atmospheric pressure at a given location depends on what?

Why is atmospheric pressure higher when air is colder and lower when air is warmer?

• cold air has less air particles than hot air

• cold air is denser than hot air

• hot air is found at lower altitudes than cold air

• cold air can build more pressure than warm air

Wind is caused by

• atmospheric changes involving humidity, precipitation, and temperature.

• global ocean waves as they crash against the shoreline.

• seasonal variations in the axial tilt of Earth as it orbits the sun.

• air moving from a region of high pressure to a region of low pressure.
