Continental crust is defined as having higher concentrations of very light elements like K, Na, and Ca, and is the lowest density rocky layer of Earth. Its average composition is similar to granite.
The crust, with an average density of around 2.6 grams per cubic centimeter (g/cm3), is less dense than the mantle (average density of approximately 3.4 g/cm3 near the surface, but more than that at depth), and so it is floating on the “plastic” mantle. Earth's interior layers are ordered by density. The densest layer is the solid metal inner core, the mantle is of intermediate density, and the least dense layer is the lithosphere, particularly the continental lithosphere Earth's Crust. “Crust” describes the outermost shell of a terrestrial planet. Earth's crust is generally divided into older, thicker continental crust and younger, denser oceanic crust

In December 1978, Vietnamese troops fought their way into Cambodia. They captured Phnom Penh on January 7, 1979. ... In 1982, the Khmer Rouge formed a coalition with Prince Sihanouk, who was exiled in China after the Cambodian Civil War, and the non-communist leader Son Sann to create the Triparty Coalition Government.
Answer: The name of the biome is Tundra.
Explanation:
Tundra is the coldest of all the biomes. Tundra comes from the Finnish word tunturi, meaning treeless plain. It is noted for its frost-molded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. Dead organic material functions as a nutrient pool. The two major nutrients are nitrogen and phosphorus. Nitrogen is created by biological fixation, and phosphorus is created by precipitation.
Characteristics of tundra include:
Extremely cold climate
Low biotic diversity
Simple vegetation structure
Limitation of drainage
Short season of growth and reproduction
Energy and nutrients in the form of dead organic material
Large population oscillations.
Definition of Term:

What is a biome? Biomes are very large ecological areas on the earth's surface, with fauna and flora (animals and plants) adapting to their environment. Biomes are often defined by abiotic factors such as temperature, climate, relief, geology, soils and vegetation.
Utilising the chart provided, I can see that every county listed here have a human development index (HDI) of 0.9 or above and also show wealthy countries such as the United States, Germany, Ireland and Norway.
Based on these results, I can confidently announce that the answer is D.
Relic Boundary is the correct answer :)
