How long does it take for rain to get to Earth?

Its difficult to give an exact figure as the height at which raindrops fall and their size vary widely, but given that raindrops fall at an average speed of around 14 mph and assuming a cloud base height of around 2,500 feet, a raindrop would take just over 2 minutes to reach the ground.

How long does it take rain to reach the Earth?

In still air, the terminal speed of a raindrop is an increasing function of the size of the drop, reaching a maximum of about 10 meters per second (20 knots) for the largest drops. To reach the ground from, say, 4000 meters up, such a raindrop will take at least 400 seconds, or about seven minutes.

What if rain fell all at once?

Originally Answered: What if rain came down all at once and not in tiny raindrops ? Then we would all die. Not from the rain but because of the lack of oxygen. Moisture in the air can only condense into droplets of water when cooled down by the adiabatic effect of a lesser pressure.

Where does rain go when it hits the ground?

Much of the rain that enters the ground filters down into subsurface water-bearing rocks (aquifers) and eventually reaches lakes, streams, and rivers where these surface-water bodies intercept the aquifers.

At what speed does rain fall?

In general, depending upon their size, raindrops fall between 15 and 25 miles per hour no matter how high they are when they begin their descent. Not all falling objects have the low terminal velocity of raindrops.

What is a cloud seeding?

Cloud seeding is a weather modification technique that improves a cloud’s ability to produce rain or snow by artificially adding condensation nuclei to the atmosphere, providing a base for for snowflakes or raindrops to form.

What falls faster rain or snow?

In “Snow science: What is snow?,” we learn that snowflakes are solids. As a solid, this form of precipitation floats to the ground much slower than other forms of precipitation, such as rain. Rain falls faster and has a sound upon impact with the ground or another surface, making it a much louder form of precipitation.

Why does rain not hurt when falling?

When the droplets move so fast that the air resistance equals the force of gravity, the raindrops cannot fall any faster, thus they are at “terminal velocity”. Raindrops do not have a fast terminal velocity, so they can’t fall fast enough to hurt us.

Why do raindrops fall so slow?

A falling object reaches what’s known as its terminal velocity when friction — the slowing force of air — cancels the downward pull of gravity. That means the drop stops speeding up and keeps falling at a steady rate.

Is it possible for it to rain everywhere at once?

Due to low humidity in this air, it is impossible to get rain in all tropics at once. Furthermore, there is an issue with polar areas – if it rains on both the South Pole and the North Pole. South Pole is located at high altitude on Antarctic ice sheet.

What would happen if a cloud fell?

It would either be very foggy or very wet if they fell all at once emptied our atmosphere of all water vapor. The results would vary on the terrain and it’s ability to handle high levels of rainfall. Rivers can only hold so much . major flooding some areas would just soak it up.
