What do you mean by flooding the streets?

It rained heavily and the streets were flooded with rain.

The water drops falling from the clouds and the water on the land and sea surface evaporate into steam. When the steam rises to a certain height, it becomes small water drops when it is cold. These small water droplets form a cloud, where they collide with each other and merge into large water droplets. When it is too big for the air, it will fall from the clouds and form rain.

Rain is the most important fresh water resource in human life, and plants thrive on the moisture of rain and dew. But the flood caused by rainstorm will also bring great disaster to mankind.

Function:

1. Rainwater is an indispensable part of the earth, and it is also the only way for almost all terrestrial plants far away from rivers to replenish fresh water.

Rainwater can irrigate crops and is beneficial to afforestation.

Rain can reduce dust in the air and lower the temperature.

4. Rainwater is beneficial to reservoir water storage, groundwater recharge and river water replenishment, and is beneficial to power generation and shipping.

Rain can isolate the noisy world, create a quiet environment, hypnotize and wash the streets.

6. Rainwater can wash away ground garbage, dilute toxic substances and purify the environment.
