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.
Improper agricultural methods may elevate concentrations of nutrients, fecal coliforms, and sediment loads. increased nutrient loading from animal waste can lead to eutrophication of water bodies which may eventually damage aquatic systems.

Explanation:
Evolution can be define as the change that occur in a particular species over a time. Such changes are because of natural selection of favorable traits responsible for the survival of the organisms under unfavorable conditions.
a. Increasing phenotypic complexity over time: Some of the phenotypic traits make the organism suitable for survival of the species. These traits are transferred to the members of the next generation. This process leads to the development of new species.
b. A change occurring in individuals as a result of selection: The evolution is a change that occur after the process of natural selection as the organism adapts according to the traits they exhibit.
c. Descent with change: The ancestors are the organisms which undergoes changes such changes are transferred to the new generation that is descents.
