If a country is isolated, it will have to produce everything that it needs: especially food clothes and medicine. It won't be able to specialize, but it will have to focus on satisfying the needs of the people.
If it is not isolated, it can specialize in the things that it can produce the best and fastest, and hope to exchange it for the things that it can't produce.
An archipelago...........
their relative densities
Explanation:
The relative densities of the earth's materials can be inferred by the arrangement of the earth layers.
Compositionally, the earth is made up of three distinct layers; core, mantle and the crust.
- The crust is the thin outermost layer of the earth.
- The mantle straddles the zone between the core and crust.
- The core is the innermost layer of the earth.
During the formation of the earth, materials differentiated into different layers based on density.
The densest materials settled in the core and they are made up of iron and nickel metals.
The lightest materials of silicate affinity partitioned to the crust.
The mantle contained materials whose density straddles between the crust and core.

Answer:
Difference is given as under
Explanation:
- Mountain belts or mountain ranges are a line of hills connected by high ground. Usually an orogeny most of them are a result of plate tectonic effects and maybe young may be old depending upon their characteristic composition. Like the Himalayas is a young fold mountain formed in the tertiary system of rocks.
- Usually, the mountain is separated from highlands, valleys, and passes. Usually, they tend to regulate the climate affecting snow and rainfall patterns. As compared to the stable interiors upon concerning their age are mostly young as they are continuously on the move and their formation is impacted by erosion and continuous wear and tear of geomaterials.
- Concerning the height, the continents are lower as compared to the high elevated landmasses. Though the continents have large landmass and landscape is composed of various elements as mountain belts are smaller as composed to chains connecting the continents at the edges and borders.
- Only continental mountain belts like the arctic and antarctic circle have a large scale of mountain chains and ranges on earth that are since millions and billions of years ago the formation of super landmasses.
I believe it's globular and open are the main types.
