Answer:
Explanation:
Desertification:
The process of the land degradation in arid , semi - arid , and sub - humid areas because of the factors , human activities , climatic variations .
This process lead to persistent degradation of the dry land and ecosystem because of some variation in climate and man - made activities .
The major cause of Desertification are -
1. Overpopulation
2. Overgrazing
3. Deforestation
4. Unsustainable agriculture techniques
5. Climate change
6. Stripping of land resources .
7. Overgrazing of the land by the cattle and wild stock.
Answer:
1. They usually host three or more ecosystems where animals can’t live.
4. They usually host one ecosystem with a variety of plants
Explanation:
A mountain ecosystem has more than one ecosystem. This is mainly due to the diversity of climate that this environment promotes. Due to its proximity to the ocean, slope and elevation, the mountain ecosystem promotes different areas that create different ecosystems, some more humid and others drier.
In this environment there is usually a wide variety of plants, but not animals.

The first thing to say is that there are two geographical features with the same name: the Rocky Mountain System and the Rocky Mountains (s.s.) that are part of it.The complete orographic system is something like a very varied sample of geological and tectonic processes.The system extends for more than 2982 miles, from Canada to the southern United States, (state of New Mexico). Its transverse extension varies between 68 and 300 miles, with the eastern edge being very close to Denver, and constituting a prominent feature within the central plains of the continent.The far west is not far from Salt Lake City, Utah, and is separated from the Sierra Nevada, Cascade, and Coastal chains-farther west-by the Great Basin and the Columbia River Plateau.The Rocky Mountains end before entering Alaska, not the System that contains them, which is also known to include the highest peaks in North America. In the United States, the highest height is recorded at Mount Elbert in Colorado, showing 4,401 m.s.n.m.Also in the Rocky Mountains is the watershed of the continent, which obviously separates the basins that drain towards the Pacific from those that drain towards the Atlantic.
Answer:
The correct response is that it accurately depicts Option D: the coasts of Western Europe and Africa.
Explanation:
The Piri Reis is a map dated about 1513 and it was developed by an admiral and cartographer of the same name, Peri Reis. It is significant because it shows a very early interest in world exploration but there are several inaccuracies evident. The southern tip of South America is not accurate nor is the coastline in North America except for what might be Newfoundland. The most accurate parts of the map are the coasts of Western Europe and North Africa, and the coastline of Brazil is also fairly accurate across the Atlantic.
