Which modern-day nations occupy much of the territory of the Khmer Empire?

Answers

Answer:

Modern-day nations that occupy much of the territory of the Khmer Empire are Cambodia and Thailand, with smaller areas of it being in Vietnam, Laos, and China.

Explanation:

The Khmer Empire was a well-developed empire that was located in the mainland part of Southeast Asia. It was the dominant force in the region for several hundred years, and it managed to achieve multiple great things. This empire, at its peak, was so powerful that it managed to defeat the Mongols and stop their expansion in the region, even though the Mongols were very close to their base and were at the height of their power.

The majority of the territory of the Khmer Empire was located on the territories of modern-day Thailand and Cambodia, being spread on almost all of their territories. It was not just these two though, but the southern part of Vietnam, what is now the border area of Laos with Thailand, and even a little bit of southern China, were part of this great empire.

structural adjustment loans
B.
International Monetary Fund loans
C.
World Bank loans
D.

Answers

Answer:

A. structural adjustment loans

Loans given in exchange for governmental and economic reforms are called structural adjustment loans. Therefore, correct option is A.

A structural adjustment is a set of economic reforms that are required for a country to secure a loan from the International Monetary Fund and/or the World Bank. Usually it is a set of economic policies, such as reducing government spending or allowing free trade.

Three main objectives of structural adjustment loans (SALs) are to boost economic growth, reduce poverty, and address balance of payments deficits.

As a first step structural adjustment loans, sold gold held in trust funds and accepted donations from donor countries to fund the loan. The repayment of trust funds and interest earned constitute the basis for subsequent loans. The SDR is the accounting unit of the loan, and the loan disbursement and repayment are both in US dollars.

A country's structural adjustment loans quota is usually proportional to its contribution to the International Monetary Fund. Thus, Loans given in exchange for governmental and economic reforms are called structural adjustment loans.

Describe the main characteristics of wave-dominated, tide-dominated, and rocky coastal environments.

Answers

Answer:

The characteristics of the given contexts are described in the below portion.

Explanation:

Characteristics of Wave-dominated:

They were mostly viewed by significantly higher wave power throughout the mouth particularly in comparison with tide power generation. Located at the mouth, the additional mass was indeed strong compared to some kind of summing made of heavy wave and tidal energy sources.

Characteristics of Tide-dominated:

They were mostly differentiated by considerably large tidal power throughout the throat roughly equivalent to high processing speed. Close to just the mouth, energy density would be significant although both tidal intensities are produced but instead wave energy does seem to be conservative.

Characteristics of the rocky coastal environment:

It has been well managed but it does have guaranteed coastal water. This same coast in discussion seems to be the neighborhood but rather a demarcation between some of the surrounding landscape. These rock layers possess shallow roots because otherwise, the soil seems to have a negligible nutritional value and an even more soil physical solubility.
