A closed system is a system in which matter is prevented from being removed or brought in. Biosphere 2 provides us with an example of a closed system. This is because it was specifically designed to remain isolated from external materials in order to maintain a completely separate environment inside.

The Aral Sea is bordered by two Central Asian countries.

Explanation:

The Aral Sea is located in Central Asia. It is in the territory of two countries, roughly divided in half, with the northern half being in Kazakhstan, and the southern half being in Uzbekistan. Despite the name, it is not actually a sea, but instead it is a lake, which is remnant of a former ocean that existed tens of millions of years ago. It has been called sea because of its saline water.

The Aral Sea though is on the verge of drying out. The main reason for this has been that the local population is using extensively the waters of Amu Darya and Sir Darya, which are the two rivers that supply the lake with water. Having its water income significantly reduced, and being in a very dry area, the evaporation surpasses the flow of water coming into the lake, so it has gradually been drying out.

Other lakes in the region are:

  • Caspian Sea
  • Lake Bolkhash

What two obstacles do less developed countries face? How do they approach development?
Kaylis [27]

Answer:

<em>Developing countries two major issues, of low incomes and eventually lower tax collections.</em>

Explanation:

Obstacle 1: Developing countries usually have a population with a low income. There are a lot of poor people, very few businesses are documented and there are very few well established larger corporations.

Obstacle 2: Lower income results in a low tax collection for the country. This means that the government is not able to meet its basic infrastructure resulting in underdeveloped health facilities and basic infrastructure.

In order to improve this, they look for either foreign direct investment into their country or take out loans from international banks to fund basic needs.

If done well, countries can escape from poverty. However if loans are mismanaged, countries can quickly find themselves burdened with rising debt and more poverty.
