Answer:
option (c) 14.7 lbs
Explanation:
Data provided in the question:
Area of the column = 1 square inch
Now,
we know Air pressure at the ground surface level from the atmosphere
= 14.7 Psi
also, it can be represented as
14.7 Psi = 14.7 pounds per square inch
Therefore,
Weight of the air weigh within a column that is 1 square inch in area
= Air pressure × Area
= 14.7 pounds per square inch × 1 square inch
= 14.7 pounds i.e 14.7 lbs
Hence,
The answer is option (c) 14.7 lbs
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.

Explanation:
The Horn of Africa is part of the African continent that has the shape of a horn, thus the name of it. It is located in the northern part of Eastern Africa. The area is mostly dominated by a high plateau, while the coastal parts have coastal plains. The four countries that occupy territory on the Horn of Africa are:
- Djibouti
- Eritrea
- Ethiopia
- Somalia
Ethiopia is the largest country in this part of Africa, and it occupies the central and western parts of it. Somalia is the second largest country here, and it occupies the majority of the eastern coast. Eritrea an Djibouti are the two smaller countries on the Horn of Africa, occupying its north and northeastern part.
