All the following are true of the movement of Earth's atmosphere except:

a. cool air is denser than warm air so it tends to sink toward the Earth's surface.

b. the movement of air within the atmospheric convection cells generates the Earth's major wind belts.

c. a column of cool, dense air produces high pressure at the Earth's surface. a column of warm, less dense air produces low pressure at the Earth's surface.

d. warm air is less dense than cool air so it tends to sink toward the Earth's surface.

All are true of the movement of Earth's atmosphere except:

d. Warm air is less dense than cool air so it tends to sink towards the Earth's Surface.

Explanation:

When gases heat up, their volume increases and density decrease. A decrease in density causes a substance to become lighter. Thus, when air warms up due to heat from the sun its density decreases and it gets lighter. So, it will move up. The Cooler air in turn is denser and heavier so it will sink towards the Earth's surface. Hence, the statement d, which states that 'warm air is less dense than cool air so in tends to sink towards the Earth's Surface' is FALSE.
