Can a tornado be caused by thunderstorm?
Yes, tornadoes can be caused by thunderstorms. Specifically, tornadoes can form within supercell thunderstorms, which are intense rotating thunderstorms that have the potential to produce tornadoes due to the combination of wind shear and instability in the atmosphere.
What must be present for igneous and sedimentary to form into metamorphic rocks?
Pressure and heat.
Why does the wind blow into a thunderstorm?
Winds blow into a thunderstorm because of differences in air pressure. Air from surrounding areas with higher pressure rushes into the lower pressure area of the thunderstorm, resulting in wind movement towards the storm.

What must happen in the atmosphere for a thunderstorm to become a tornado?
A thunderstorm does not become a tornad; it produces one. To start off, in most cases the storm must encounter strong wind shear, or a shift in wind speed and direction with altitude. This sets the storm rotating, turning it into a supercell. If the storm develops in the right manner, a downdraft may descend from the rare portion of the storm and wrap around the mesocyclone, or rotating updraft of the storm. This causes the mesocyclone or a portion of it to tighten and intensify, forming a tornado.
Can a tornado be caused by thunderstorm?
Yes, tornadoes can be caused by thunderstorms. Specifically, tornadoes can form within supercell thunderstorms, which are intense rotating thunderstorms that have the potential to produce tornadoes due to the combination of wind shear and instability in the atmosphere.
