Airspace is a layer (or layers) of gas that surrounds a planet and is kept in place by the planetary body's gravity. When the gravity is strong as well as the temperature and pressure are low, a planet preserves its environment.
The correct answer is B. Air pressure decreases as you increase in altitude.
The hydrogen atoms are drawn towards the earth's core by gravity. At water level, space-time pulls enormous and pushes you back to the center. At the water level, where the force of gravity is higher, the air gets denser. The gravity of the environment above them likewise compresses gases at sea level.
Pneumatic pressure is the amount of the earth pressing on a unit of air. The environmental concentration is lower and the air is less dense at high elevations than at lower altitudes.

Answer: B.
Air pressure decreases as you increase in altitude.
Explanation:
Gravity pulls the gas molecules towards the center of the earth. This pull of gravity becomes stronger and closer to the center at sea level. Air becomes dense at sea level where the gravitational pull is stronger. Gases at the sea level are also compressed by the weight of the atmosphere above them. The force of the earth weighing down over a unit air is known as atmospheric pressure. At higher altitudes, the atmospheric pressure is lower and the air is less dense than at higher altitude.
b. 2
c. 3
d. 4
Answer:
The answer is b 2 ways.
Explanation:
The first way is the Earth orbiting the sun. The second way is, while orbiting the sun it also spins on it's axis.
Answer:
Pastoral farming is aimed at producing livestock, rather than growing crops. Examples include dairy farming, raising beef cattle, and raising sheep for wool. In contrast, arable farming concentrates on crops rather than livestock.
Explanation:
b. crinoid
c. pectinoid
d. bryozoan
