What is a biome? In a short paragraph of at least three or four sentences, explain how areas can be grouped together into biomes
Aleksandr [31]

Answer:

A biome is an enormous ecosystem, spreading over a broad geographic range.

Explanation:

Biomes are classified here in such a form as to get into account their corresponding ranges and similar weather. All climate zones, though, come into one of three essential classifications: tropical and subtropical, temperate, and polar and subpolar.

The first of specific categories is a term covering the area along the equator, spreading north and south by approximately 30 degrees in either direction. In North U.S, this would involve southerly Florida, Texas, and Louisiana. Temperate areas spread from about 30 to 60 degrees on each side of the equator, thus leading in most of America. Ultimately, subpolar and polar regions lie among 60 degrees and the poles, which occur at 90 degrees.

Outline the significance of adiabatic temperature gradient in determining the earth’s convective stability ​
Vilka [71]

Answer: Adiabatic temperature gradient is the rate of change in temperature due to pressure under adiabatic conditions.

Explanation:

The rate of change of temperature due to pressure under adiabatic conditions is referred to as adiabatic temperature gradient.

In practice, since in the sea the pressure changes can be considered proportional to depth changes, the adiabatic temperature gradient is usually given as rate of change per unit depth, instead of per unit pressure and for practical purposes and calculations, the unit of depth is often chosen as 1000 m.

The natural and non-natural heat transfer influence the process of adiabatic temperature gradient.

29. Ultramafic igneous rocks have a high content of A. diamond B. potassium C. hydrogen D. ferromagnesian minerals E. carbon is
Alexus [3.1K]

Answer:

D. Ferromagnesian minerals

Explanation:

An igneous rock (formed from the solidification of molten rock material) with a very low silica content (less than 45%), low potassium content and rich in minerals, more than 90% magnesium (MgO) and iron (FeO), is known as ultramafic igneous rock (also known as ultrabasic rocks), they are dark-colored, found in orogenic (mountain-forming) belts and they are used for scientists to understand geological processes in the Earth's history. Examples include peridotite, kimberlite, lamprophyre, lamproite, dunite, and komatiite.

<em>Considering this information we can conclude that D. Ferromagnesian minerals are the correct answer. </em>

I hope you find this information useful and interesting! Good luck!
