Answer:
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.
