Answer:
a. It would shrink
b. It would expand
Explanation:
a. Since the water bottle is filled with air at atmospheric pressure at 20000 ft, and since atmospheric pressure decreases with altitude, when we go up in elevation.
The pressure exerted by the molecules of air in the water bottle seek to balance out the atmospheric pressure as we go higher. Since the atmospheric pressure exerted by the molecules of air in the atmosphere are greater than that exerted by the molecules of air in the water bottle, this causes the volume of the water bottle to decrease and thus shrinks the water bottle until the pressure balances out
b. Since the water bottle is filled with air at atmospheric pressure at 20000 ft, and since atmospheric pressure increases with decreasing altitude, when we go down in elevation.
The pressure exerted by the molecules of air in the water bottle seek to balance out the atmospheric pressure as we go lower. The water bottle expands until the atmospheric pressure outside equals the pressure inside the water bottle.this causes the volume of the water bottle to increase and thus expands the water bottle until the pressure balances out
The right answer for the question that is being asked and shown above is that: "D) The magnetic north and south poles of Earth are interchanged." The statement that best describes an effect of changes in Earth's magnetic field is that D) The magnetic north and south poles of Earth are interchanged.<span>

A is possible but unlikely as the concrete will be HUGE!
B is also unlikely as the ice will melt as it is broken down by bulldozers n turn into water!
C is impossible as it requires a LOT of fish.
D. the water is frozen solid as the temperature drops each winter and the ice melts when the temperature increases again is the best explanation.
