Raindrops don't generally hurt us having fallen all that way because they don't gain enough kinetic energy to do so. They do reach terminal velocity, and can even be pushed by downdrafts, but there's something else going on. A raindrop falling in air experiences deformation as it falls, and this changes its aerodynamics to prevent it from falling faster. The drop actually "flattens" somewhat as it falls toward a target below. Air resistance has "saved" us by deforming the droplet and limiting the amount of energy it can gain through its freefall.
If you exclude the resistance the air has on the two raindrops, both the small and the lager raindrops will travel at the same speed i.e. 32ft a second every second (The first second 32ft, the second second 64ft per second and so on). But because we do have air resistance which will resist the gravitational attraction, the raindrop with the larger mass will reach the ground first. As a point of further interest, if an object falls from a very high altitude the resistance of the air will equal the pull of gravity and the object will continue to fall at the same speed, this is called terminal velocity.
At high altitudes, the air is thinner and there is less pressure. This causes the air to expand and cool down, leading to lower temperatures.
At high altitudes, the lower air pressure can lead to decreased oxygen levels in the blood, causing symptoms like shortness of breath, fatigue, and headaches. In severe cases, it can result in altitude sickness, which may include symptoms like nausea, dizziness, and confusion. It is important to acclimatize slowly to high altitudes to avoid these effects.
Ultraviolet rays are more dangerous at high altitudes because the atmosphere is thinner, offering less protection from the sun's radiation. This means that more UV radiation reaches the earth's surface at higher elevations, increasing the risk of sunburn and skin damage. Additionally, the reflection of sunlight off snow and ice can further intensify UV exposure at high altitudes.
A fountain pen may leak at high altitudes due to changes in air pressure. As the air pressure decreases at higher altitudes, the pressure inside the pen may become greater than the external pressure, causing ink to leak out. Additionally, fluctuations in temperature can also affect the viscosity of the ink, leading to potential leaks.
Pellets of ice that form when updrafts in thunderstorms carry raindrops to high altitudes, where the water freezes and then falls back to Earth.
Updrafts in cumulonimbus systems can cause some rain drops to rise up. They reach high altitudes where the temperatures are low enough for the droplet to freeze. They can then fall, collecting a layer of water on the outside, then rise again to form a larger hail stone. Eventually the hailstone is too large for the updraft to raise it. But away from the core of the updraft, the condensed raindrops can fall as normal rain.
Raindrops falling under gravity do not gain very high velocity due to air resistance. As raindrops fall through the atmosphere, they experience a force opposite to their direction of motion, which slows them down. The balance between gravity and air resistance limits the maximum velocity that raindrops can achieve.

Hail is formed in severe thunderstorms with strong updrafts that carry raindrops to high altitudes where they freeze. It is not always present in the atmosphere but occurs when specific conditions are met in thunderstorms.
If you exclude the resistance the air has on the two raindrops, both the small and the lager raindrops will travel at the same speed i.e. 32ft a second every second (The first second 32ft, the second second 64ft per second and so on). But because we do have air resistance which will resist the gravitational attraction, the raindrop with the larger mass will reach the ground first. As a point of further interest, if an object falls from a very high altitude the resistance of the air will equal the pull of gravity and the object will continue to fall at the same speed, this is called terminal velocity.
Hail forms when strong updrafts in thunderstorms carry raindrops high into the cold upper atmosphere, where they freeze into ice. These ice pellets then fall to the ground as hail.
Raindrops are Round...At First.Raindrops start out as round high in the atmosphere as water collects on dust and smoke particles in clouds. But as raindrops fall, they lose their rounded shape. Instead, a raindrop is more like the top half of a hamburger bun. Flattened on the bottom and with a curved dome top, raindrops are anything but the classic tear shape. The reason is due to their speed falling through the atmosphere
Cirrocumulus cloud is a clous that often appears at high altitudes.
Jet airplanes fly at high altitudes because it is more fuel efficient. Flying at higher altitudes uses less fuel than flying at lower altitudes.
High altitudes generally have lower temperatures compared to lower altitudes. This is because the air at higher altitudes is less dense and can hold less heat, leading to cooler temperatures.
It is greater at a lower altitude.
