Answer:
The correct answer is - loss of soil moisture east of mountain ranges.
Explanation:
Air or wind with moisture moves towards the top of the mountains where it precipitates and condenses before crossing the mountains and when this air crosses there is no moisture left in them to precipitate on another side.
The other side called rain shadow and is forced to become the area desert in the long run which is called the rainshadow effect. The major effect of the rainshadow effect is the formation of the deserts in a natural way.
Small fragments of orbiting bodies that have landed on Earth are known as meteorites. If the fragments are still orbiting earth are known as meteoroids. They are not called meteorites until they enter Earth's atmosphere. Once a meteor enters Earth's atmosphere it will begin to burn up. It may burn up completely or lose most of its size by the time is lands on Earth's surface.
Answer:
2. A change occurs in the environment.
4. Poorly adapted individuals have decreased survivorship.
1. Well-adapted individuals leave more offspring than do poorly adapted individuals.
3. Genetic frequencies within the population change.
Explanation:
The natural selection theory was developed by Darwin to explain how evolution occur within a population. The environment is in constant state of changes and always select for organisms that are better adapted to it.
Poorly adapted organisms gradually reduce from the population as a result of decreased survival while well-adapted individuals multiply and contribute more to successive generation.
Well-adapted individuals pass on the adaptive alleles to their offspring, eventually leading to a change in gene frequencies within the population.
Hence, the sequence of events is 2, 4, 1 and 3.
Examples
High respiration rates from mass global population
Deforestation
