Why does rain fall as droplets?

To form rain, water vapour needs what’s called a condensation nucleus, which can be tiny particles of dust, or pollen, swept up high into the atmosphere. When the condensing droplets that form the cloud get large and heavy enough to overcome the upward pressure of convection, they begin to fall.

How rain droplets are formed?

Raindrops begin forming when water vapor condenses on micrometer-sized particles of dust floating in the atmosphere. The dust particles grow to millimeter-sized droplets, which are heavy enough to begin falling.

Why does rain come down as drops instead of as a larger mass of water?

Rain forms in clouds as water vapor gloms onto dust or other tiny particles, gradually building up. Because these infant drops are relatively packed together in the cloud, they collide with one another and coalesce into larger drops. First, the falling spherical drop gradually flattens out into a pancake shape.

What is rain droplet?

In order to have rain you must have a cloud — a cloud is made up of water in the air (water vapor.) Each particle (surrounded by water) becomes a tiny droplet between 0.0001 and 0.005 centimeter in diameter. (The particles range in size, therefore, the droplets range in size.)

What are raindrops compared to and why?

Answer: Raindrops are compared to coins because Lencho wrote letter to god to sent rupees directly to him.

What is the droplet of water?

A drop or droplet is a small column of liquid, bounded completely or almost completely by free surfaces. A drop may form when liquid accumulates at the lower end of a tube or other surface boundary, producing a hanging drop called a pendant drop.

Why do water droplets bounce on water?

It happens when the surface is hydrophobic – which means it essentially repels water. The surface tension in the droplet tries to make the contact point as small as possible and so it pulls it into a ball.

How would you describe raindrops falling?

“Pitter-patter” means light sounds or beats, and often is used to describe the sound of small animals (like cats) as they gently move about. It has a fairly positive and easy-going connotation, and using “pitter-patter” to describe rain invokes a sense of melody and calm. The rain sprinkled on the roof top.

What causes rain to fall in drops?

Why does Rain Fall in Drops. First, rain is generated within droplets in clouds, and second, air resistance rips large amounts of water apart as it falls toward the ground. When warm, moist air moves upward, it gets cooled by the lower temperature of the atmosphere; the resulting vapor condenses into droplets, generating clouds.

What are the two ways that Rain is formed?

First, rain is generated within droplets in clouds, and second, air resistance rips large amounts of water apart as it falls toward the ground. When warm, moist air moves upward, it gets cooled by the lower temperature of the atmosphere; the resulting vapor condenses into droplets, generating clouds.

How do clouds form and what causes precipitation?

When the condensing droplets that form the cloud get large and heavy enough to overcome the upward pressure of convection, they begin to fall. Although all clouds contain water, some produce precipitation and others drift away placidly without giving rain. First all the droplets in a cloud are less than 20 micrometer in diameter.

What is the difference between rain and clouds and rain drops?

In a cloud there are lot hygroscopic particles and normally drops form by absorbing moisture by these particles. Rain is restricted to drops of water that fall from a cloud. They have a typically diameter of at least 0.5 mm.
