Why does it rain scientific explanation?

Water vapor turns into clouds when it cools and condenses—that is, turns back into liquid water or ice. In the cloud, with more water condensing onto other water droplets, the droplets grow. When they get too heavy to stay suspended in the cloud, even with updrafts within the cloud, they fall to Earth as rain.

Why does it rain unexpectedly?

Scientists found that cumulus clouds can create rain showers in a matter of minutes when atmospheric turbulence exceeds a threshold, greatly increasing the rate of droplet collisions. Dark clouds may form slowly throughout the day before a drop of rain falls, and sunny days can suddenly transform into thunderstorms.

Why it rains after a hot day?

Warm air can hold more moisture than cool air. When the warmer air is cooled and the moisture condenses, it often rains more heavily.

Why does it mostly rain at night?

Air is generally cooler at night, and cool air holds less moisture than warm air resulting in rainfall.

Why does it rain only in rainy season?

Many tropical and subtropical climates experience monsoon rainfall patterns. Rainfall in the wet season is mainly due to daytime heating, which leads to diurnal thunderstorm activity within a pre-existing moist airmass , so the rain mainly falls in late afternoon and early evening in savannah and monsoon regions.

How is rainfall formed?

Precipitation forms in the clouds when water vapor condenses into bigger and bigger droplets of water. When the drops are heavy enough, they fall to the Earth. Most rain actually begins as snow high in the clouds. As the snowflakes fall through warmer air, they become raindrops.

What is rainfall in geography?

Definition: Rainfall is a measurement of how much water falls as rain in a certain period of time, for example, a week or a month. Rainfall is measured by collecting rain water across different areas and times, as the amounts may differ between locations and times.

What part of the world rains the most?

Mawsynram
Mawsynram, India Mawsynram, located in the Meghalaya State in India, is the wettest place in the world. It receives an annual rainfall of 11,871 millimeters. The mountainous terrain of the surrounding land forces the northward-moving warm moist monsoon winds coming from the Bay of Bengal to converge over Mawsynram.

Why raining season is better than dry season?

The fresh water rain provides is essential to the survival of every living organism, from plants to animals to humans. Fresh water sources are depleted by the natural process of evaporation, and rainy days replace that lost water. Plus, it’s just so pretty when it rains!

What is rain made of?

Rain is liquid precipitation: water falling from the sky. Raindrops fall to Earth when clouds become saturated, or filled, with water droplets. Millions of water droplets bump into each other as they gather in a cloud. When a small water droplet bumps into a bigger one, it condenses, or combines, with the larger one.
