about 9,000 mph.
Clouds move fast across the sky due to the wind. The wind pushes the clouds along, causing them to travel quickly.
When clouds are moving fast across the sky, it usually means that there is strong wind at higher altitudes pushing the clouds along.
A volcano is a rapid change because it can go from a state of dormancy to eruption very quickly, often with little warning. The eruption itself can cause immediate and widespread changes to the surrounding environment, affecting landscapes, ecosystems, and communities in a short period of time.
Clouds move fast sometimes due to strong winds in the upper atmosphere. These winds can push the clouds along quickly, causing them to move rapidly across the sky.
Tephra refers to fragmented volcanic material ejected during an eruption, including ash, lapilli, and bombs. Pyroclastic flow is a fast-moving mixture of hot gas and volcanic particles that flows down the side of a volcano during an explosive eruption, capable of reaching speeds of hundreds of kilometers per hour and causing widespread destruction.
two miles per hour
The Black Death spread across Europe at 4km
The cloud of gas from the Laki eruption in 1783 spread across Europe at a rate of about 20-25 miles per hour. It led to widespread environmental and health impacts, including poor air quality and crop failures.
Laki is a volcanic fissure in southern Iceland that erupted for over eight months. The poisonous gases spread through Europe from summer to autumn.
It first developed in rome, but moved up into Europe quickly. Germany is part of Europe
Yes Buddhism spread fast in India.
Judaism spread fast so equals yes
Fast
It happened gradually, as Jews moved to new areas in Europe, western Asia and the Mediterranean region.
In the case of Hawaii's volcano, slow moving lava creates new land over time, as the lava meets the ocean. In the case of Mt. Vesuvius, it was a powerful explosion with fast moving flows that completely buried the cities of Pompeii and Herculaneum. The ash from a recent Icelandic eruption caused airline cancellations and delays for weeks all across Europe.
An explosive volcanic eruption. Pyroclastic flow is a mixture of fast flowing hot gases that travel down and away from the eruption.
fast.......really,really fast!
