Explanation:
Afghanistan is a country that has proved to be extremely difficult to invade, and that has been the case for thousands of years. There is one major reason for this, the geography of the country. The country is dominated by very high mountains that create rain shadow and and deserts. The mountains themselves are extremely difficult for passing through, and even if they are passed by an invading army, they will take their toll. Once the mountains are passed, an invading army would face desert, very dry climate, very few food sources and very little water, with temperatures varying from scorching hot in the summer, to freezing cold in the winter. So even if an army passes through both of these natural obstacles, when it comes to face the natives it will be too weak to invade.
The Rocky Mountains are described as younger because the Rocky's are really two mountain chains. The older mountain chain started billions of years ago, and the younger mountain chain pushed the older mountain chain up more, only 60 millions years ago.
Answer:
c.The atmosphere, a plant, a herbivore, a decomposer, then back to the atmosphere.
Explanation:
The carbon cycle is the biogeochemical cycle through which carbon is exchanged between the biosphere, pedosphere, geosphere, hydrosphere and Earth's atmosphere. Together with the nitrogen cycle and the water cycle, the carbon cycle comprises a sequence of events that is key to making the Earth capable of sustaining life; describes the movement of carbon when it is recycled and reused by the biosphere, including carbon sinks.
A single carbon atom would more likely go from the atmosphere through being absorbed by a plant and, later, it would enter into the organism of a herbivore that eats the plant. After the herbivore dies, the carbon atom would enter into the organism of a decomposer that would expel it back again into the atmosphere.
