It is upward motion that produces clouds - lift air, and it expands (gravity's pull decreases with altitude) and cools (as do all gases when they expand). The moisture content remains the same, however, and once the air cools enough so that it is saturated by its moisture content, clouds will begin to form.

What are the tall puffy kinds of clouds that form by vertical motion in warm and relatively humid air?
The tall puffy clouds that form by vertical motion in warm and humid air are called cumulus clouds. These clouds typically appear isolated, with a flat base and a dome-shaped top. They are often associated with fair weather, but can develop into larger storm clouds if the atmosphere becomes more unstable.
How do clouds defy gravity?
To say clouds defy gravity would be misleading, as they do not defy gravity. However rising air currents keep the clouds in the air. The air currents are stronger than the rate at which gravity makes the rain fall (which is not that fast). Clouds are so light, that even the smallest upward air current can make a clouds stay up. Rain falling is basically when the mass of the drops exceed the air currents.
What do rain clouds signify?
Rain clouds signify that there is a high amount of moisture in the air, which may soon result in precipitation in the form of rain. These clouds are often large and dark in appearance, indicating that they are capable of producing significant amounts of rain.
What is funnel clouds that last up to 15 minutes?
Funnel clouds are rotating columns of air that extend downward from a thunderstorm cloud but do not touch the ground. These clouds can develop into tornadoes if they reach the ground. If a funnel cloud lasts for up to 15 minutes, it could indicate a higher likelihood of it touching down and becoming a tornado.
Why do some clouds pass overhead without producing rain?
Some clouds may not produce rain because they are not saturated enough with moisture, or the air below them may not be rising enough to trigger precipitation. Additionally, certain types of clouds, like cirrus clouds, are usually too high in the atmosphere to generate rain.
What force opposes the downward motion of falling object?
The force that opposes the downward motion of a falling object is air resistance, also known as drag force. This force acts in the opposite direction to the motion of the object and increases with the speed of the object.
What is downward displacement of air?
Downward displacement of air refers to the movement of air particles in a downward direction, usually caused by the sinking motion of air masses or the influence of gravity. This can result in increased air pressure at the surface and can be associated with stable weather conditions.
How do Mammatus clouds form?
Mammatus clouds form when sinking pockets of cold, dense air create pouch-like structures underneath the base of a larger cloud. These pockets are formed by the downward motion of air and moisture that condense into visible cloud droplets. Mammatus clouds are often seen following intense thunderstorms and can be a sign of turbulent weather.
If stratus clouds are dark what are they called?
Because there can be a lot of water in warm air, stratus clouds can easily turn into dark, rain and snow-producing nimbostratus clouds.
What is force that acts against a parachutes downward motion?
Air resistance, also known as drag, acts against a parachute's downward motion. As the parachute falls through the air, air molecules push against the surface of the parachute, creating a force that opposes its downward acceleration. This force helps slow down the parachute's descent, allowing for a safe landing.
What are all the forces that act on an object when it falls?
When an object falls, the main forces acting on it are gravity (pulling it downward) and air resistance (opposing its downward motion). In the absence of other factors, these two forces are the primary influences on the object's falling motion.
Clouds form in a hurricane because the air is?
moist and warm, causing water vapor to condense and form clouds. The intense upward motion of air within a hurricane also helps in the rapid formation of clouds.
What are the tall puffy kinds of clouds that form by vertical motion in warm and relatively humid air?
The tall puffy clouds that form by vertical motion in warm and humid air are called cumulus clouds. These clouds typically appear isolated, with a flat base and a dome-shaped top. They are often associated with fair weather, but can develop into larger storm clouds if the atmosphere becomes more unstable.
Which two forces affect the motion of a projectile?
The two forces that affect the motion of a projectile are gravity and air resistance. Gravity acts to pull the object downward, influencing its vertical motion, while air resistance affects the projectile's horizontal motion by slowing it down as it travels through the air.
What two forces act on a projectile in motion?
The two forces acting on a projectile in motion are gravity, which always acts downward, and air resistance, which opposes the projectile's motion through the air. Gravity causes the projectile to follow a curved path, while air resistance slows down its movement.
Projectiles are subject to what two forces?
Projectiles are subject to the force of gravity, which causes them to accelerate downward, and the force of air resistance, which opposes their motion through the air.
How does the downward component of the motion of a projectile compare to the motion of free fall?
The downward component of the motion of a projectile is influenced by the initial velocity and angle of launch, resulting in a curved path known as a projectile motion. In contrast, free fall refers to the vertical motion of an object under the influence of gravity alone, where the acceleration is constant and the path is straight.
