Answer:
The population first grows, stabilizes, and then declines.
Explanation:
A researcher is studying a population with a unique age structure. An age structured histogram he has developed over the course of several decades has undergone transformations in shape, from a pyramid shape to a roughly rectangular shape to an inverted pyramid shape (where the base is narrower than the top). The population first grows, stabilizes, and then declines.
The best answer is option D.
Acid rain is simply rainfall that has been rendered acidic due to water vapor reacting with nitrogen oxide ad sulphur dioxide very high up in the atmosphere.
Acid rain is not only a threat to the ecosystem and environment, but also seriously damages buildings and sculptures.
Marble and limestone are especially vulnerable to acid rain. This is because the two building or construction materials contain calcite which is easily dissolved by acid.
Concrete surfaces and paint finishes are also seriously damaged by acid rain.
Evaporation
Explanation:
On a hot sunny day, the stage of water cycle most likely occurring is the evaporation stage.
At this stage, a phase change is occurring and liquid water is converted to water vapor in the atmosphere.
- Evaporation is an important aspect of the water cycle.
- It is preceded by precipitation and followed by condensation in the atmosphere.
- Water rises from the surface in gaseous forms and condenses in the atmosphere.
- This is because it is less dense than the surrounding atmosphere.
