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. migration from one continent to another
c. migration from one nation to another
d. movement from a rural area to a larger town, and then to a metropolis
Step migration involves a series of smaller moves to reach a final destination, for example, moving from a rural area to a larger town and then to a metropolis.
The best example of step migration is The movement from a rural area to a larger town, and then to a metropolis. Step migration is a type of migration pattern where individuals or families don't move directly from one location to another but instead make several intermediate stops along the way. These intermediate destinations can be larger towns or small cities. Ultimately, the end destination might be a major city or metropolis, but it would not be reached immediately. Step migration is often observed in regions where rural to urban migration is prevalent, due to economic factors or in search of better opportunities.

Answer:
Person above was wrong, the answer is "the distance from the Earth to the Sun"
The geography of the United States and Canada is interconnected through various landforms such as the Rocky Mountains, the Great Lakes, and the Great Plains. These geographical links suggest shared histories, economies, and cultures influenced by landforms.
The geography of the United States and Canada is interconnected through their landforms. In essence, several key landforms link these two regions physically and ecologically. The Rocky Mountains, which extend from the southern United States all the way up to the northern tip of British Columbia in Canada, is a prominent example. In addition, the Great Lakes straddle the border between the US and Canada and serve as a key geographical connection between the two countries.
Besides these, the Great Plains also extend north into Canada from the United States, suggesting a shared agricultural history heavily influenced by geography. Understanding these physical geographical links can provide insight into the shared histories, economies, and cultures of the two countries.
