Streams erode sediment from their banks. They pick up and transport sediments. As a stream erodes its banks, it creates a V-shaped valley (Figure above). This contrasts with the U-shaped valleys created by glaciers.
The best answer to this question is:
C. A forest fire that was caused by lightning.
A forest fire could kill for example all the individuals of a certain species in a given area - this would be independent of the population density of the species. All the other factors would affect the population the more, the more dense it is.

Answer:
Answer:
The correct list is inner core, outer core, lower mantle, asthenosphere, lithosphere.
Explanation:
Based on Structural features and chemical composition earth surface is divided into different layers. The main layers can be described as,
1. Core
2. Mantle
3. Crust
Core:
The core is further divided into inner core and outer core. The inner core is extremely hot and solid. The outer core is in fluid form and surround the inner core.
Mantle:
The mantle layer is composed of rocks. The earth's mantle is also divided into two main layers Lower mantle and upper mantle. Asthenosphere is viscous and present just below the rigid lithosphere.
Crust:
Crust is the outermost layer of earth. It is composed of variety of elements. Lithosphere is the part of Crust.

By using ordinary language to describe the events surrounding the nose's disappearance arrived at this answer after reading a portion o f the story involving the disappearance of the nose. "But, to his unbounded astonishment, there was only a flat patch on his face where the nose should have been! Greatly alarmed, he got some water, washed, and rubbed his eyes hard with the towel. Yes, the nose indeed was gone! He prodded the spot with a hand—pinched himself to make sure that he was not still asleep. But no; he was not still sleeping. Then he leapt from the bed, and shook himself. No nose! Finally, he got his clothes on, and hurried to the office of the Police Commissioner. "In the above quote, ordinary language was used. It would seem as though losing a nose is no big deal for the character. Instead, he is more concerned of going to the office. His reaction is quite unbelievable.
The biodiversity and species richness has almost exclusively positive effects in every aspect, lot of which are of huge importance and benefit for the humans.
Explanation:
The biodiversity and species richness is basically the amount of species that inhabit a particular ecosystem, while on global level it represents all of the species on the planet. The more species there are on the planet, the better, and vice versa, the less species there are, the worse. The reason for this is that pretty much every species provides some benefits, which are good both for nature and for the humans. The befits can be seen from several different aspects, such as:
- economic
- agricultural
- medicinal
- ecological
The economic benefits are seen in the fact that lot of species are very interesting and attractive to the people, so some sectors, such as the tourism directly depends on the biodiversity in lot of parts in the world. For the agriculture, it is good that the biodiversity is high, as that means that the pests will be naturally regulated by their predators. The medicine is directly dependent on the biodiversity, as it relies on lot of species to produce the medicines, and if they are gone, this industry will crumble. From ecological aspect, the biodiversity and species richness is important because the communities of organisms will remain as they are, function without any problems, and be in prefect balance.
