Question

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.

Answer 1

The accurate statement about Earth's atmosphere movement is that warm air rises because it is less dense, and cool air sinks due to higher density. This creates convection currents which are essential in generating wind belts and pressure systems.

Step-by-step explanation:

The correct answer to 'All the following are true of the movement of Earth's atmosphere except:' with the listed statements is option d: warm air is less dense than cool air so it tends to sink toward the Earth's surface. This statement is false because in reality, warm air is less dense and therefore it tends to rise, not sink. This rising of warm air and the sinking of cooler air form convection currents, which are a major factor in the movement of Earth's atmosphere.

The rest of the statements are true: a. cool air is denser than warm air so it tends to sink, b. the movement of air within the atmospheric convection cells generates the Earth's major wind belts, and c. a column of cool, dense air produces high pressure at the surface while a column of warm, less dense air produces low pressure.

Answer 2

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.

Step-by-step 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.
