No. Even the strongest of tornadoes won't remove more than a couple feet of topsoil, and only in small areas. They are not a geologic force.
It doesn't make a difference.
Tornadoes can occur in valley regions, but they are more common in flat areas such as the Great Plains. When strong thunderstorms develop in valleys, they can produce tornadoes due to the right atmospheric conditions. Topography can influence how tornadoes behave in valley regions, with terrain features potentially affecting their paths and intensity.
No. Valleys do not protect from tornadoes. In fact there is some evidence that tornadoes can intensify as they enter a valley. Saginaw was hit by a tornado in 1982.
No. planes do not make tornadoes
Yes, tornadoes can form in valleys under the right conditions. Valleys can channel and intensify wind flow, which can enhance the development of a tornado. The topography of a valley can also create areas of low pressure that contribute to tornado formation.
Tornadoes occur more frequently in the Great Plains region compared to valleys. This is because the Great Plains experience more severe weather conditions like thunderstorms and have a favorable topography for tornado formation, such as flat terrain and colliding air masses. Valleys typically do not have the same conditions necessary for tornado formation.
Yes, Valleys and rivers do not stop tornadoes. If tornadoes have occurred near your town or city there isn't really anything preventing a direct hit.
No. Tornadoes occur naturally.
No, however you can make tornadoes in Sim City.
It is unclear what is meant by the average risk. A large portion of the Mississippi and Ohio valleys was under a 2% or greater risk for tornadoes. About half of that area was under a 5% risk.
What are the two valleys that make up the Central Valley in California
No. They are often associated with tornadoes and other severe weather, but there is no direct connection between them and tornadoes.
