The correct option is LOESS.
Loess refers to a compacted yellowish deposit of wind blown sediments which is usually found extensively in the mid latitudes. Loess is formed by the accumulation of dust that had been blown by the wind. Scientists believed that about 10% of the earth's land area is covered by loess.<span />
A. 40 percents of the world pop and half of the economic outcome.
Answer:
Asia and North-America
Explanation:
The Bering strait is a portion of about 47 miles (75 km) that separates Asia (Russia) and North-America (state of Alaska, USA). Let's remember that Alaska belonged to Russia and was bought by the US.
That straight is a place with very harsh and extremely violent weather fueled by cold Arctic water and winds.
20,000 years ago, that straight was solid ice and that's how human migrated from Asia to North America (and went further South afterwards).
Answer:
This is an example of Morphological and structural adaptation
Explanation:
The morphological and structural adaptation is an anatomical adaptation, where living beings exhibit some characteristics that allow them to survive according to the environment in which they are, either promoting a camouflage, or resembling animals that are dangerous to frighten possible predators.
An example of this can be seen in the question above, where the hare, in order to survive and reproduce, allow the hair to become white as snow, and can camouflage themselves in the environment in which they are.
