Does raindrop formation cause air pressure to drop or does dropping air pressure cause raindrops to form?
Dropping air pressure causes raindrops to form. As air rises, it cools and reaches its dew point, causing water vapor to condense into liquid water droplets, forming clouds and eventually precipitation. This process does not directly affect air pressure.
Why does a falling raindrop not fall faster and faster?
It does, up to a limit called "terminal velocity". Terminal velocity is reached when the force of friction against the air equals the force of gravity acting on the raindrop. As the drop falls, it hits molecules in the air, and each of those molecules slows the raindrop down just a little bit. As gravity pulls the drop down, soon it hits so many molecules per unit of time that the combined effect prevents it from gaining any more speed.
Would you expect polar air to have high or low humidity?
Polar air typically has low humidity because cold air has a limited capacity to hold moisture. As the air temperature drops in polar regions, the air becomes drier.
What caused the climate of the badlands to change?
climate cooling and drier air
How does the force of gravity on a raindrop compare with the air drag it encounters when it falls at a constant velocity?
If the vertical speed is constant, that means there is zero vertical acceleration. If the vertical acceleration is zero, that means the net vertical force on the object is zero. If the net vertical force on the object is zero, that means the downward force (weight) and upward force (air resistance) are equal.
Why are raindrops shaped like pear instead of a ball?
A raindrop would be sphere-shaped if it were floating in space or in the air, but because it does not float, but falls toward the Earth, the raindrop encounters resistance by the air. As the drop passes through the air, the relative motion of the air past the diameter of the spherical drop creates a slight vacuum at the top of the raindrop and that vacuum draws the top of the raindrop upward, creating the pear shape.

When water vapor changes into a liquid will the air gets drier or wetter?
drier couse when we have vapor air is wet and when we lost it makes air drier.
Does a raindrop lose it's thermal energy as it falls to the ground?
As a raindrop falls, it may lose some thermal energy due to air resistance and evaporation, especially if the air temperature is lower than the temperature of the raindrop. However, the main energy change during the fall of a raindrop is potential energy being converted to kinetic energy.
Why is cold air drier than warm air?
Cold air is drier than warm air because cold air has a lower capacity to hold moisture compared to warm air. This means that when cold air is heated, its relative humidity decreases, making it feel drier.
What type of force acts on a raindrop to reduce its speed?
Air resistance, also known as drag force, acts on a raindrop as it falls to reduce its speed. This force increases as the raindrop's speed increases, eventually balancing out the force of gravity and causing the raindrop to fall at a constant speed.
Is cold air drier than warm air?
Yes, cold air is typically drier than warm air because cold air has a lower capacity to hold moisture compared to warm air.
Is cold air drier than warm air?
Cold air has the potential to hold less moisture than warm air. However, whether or not cold air is drier than warm air can also depend on the humidity levels. Cold air tends to feel drier because it has a lower capacity to hold moisture compared to warm air.
Why a descending mas of air would become more drier?
As the air descends, it is compressed due to higher atmospheric pressure. This compression causes the air to warm up, increasing its ability to hold moisture. However, the total amount of moisture remains the same, so the relative humidity decreases and the air becomes drier.
Does central air conditioning make the air inside drier?
Yes, central air conditioning can make the air inside drier. As the system cools the air, it also removes humidity, which can lead to lower moisture levels in indoor environments. This can result in dryness that may cause discomfort, such as dry skin or respiratory issues. Using a humidifier can help maintain a more comfortable humidity level in air-conditioned spaces.
What is the terminal velocity of a raindrop?
The terminal velocity of a raindrop is typically around 9-13 mph (14-21 km/h). This speed is reached when the force of air resistance acting on the raindrop is equal to the force of gravity pulling it downwards.
Does raindrop formation cause air pressure to drop or does dropping air pressure cause raindrops to form?
Dropping air pressure causes raindrops to form. As air rises, it cools and reaches its dew point, causing water vapor to condense into liquid water droplets, forming clouds and eventually precipitation. This process does not directly affect air pressure.
