They aren't, really. Tornadoes can be very destructive when they do occur, but they are rare enough that they do not have a very substantial impact on most ecosystems.
No. While most tornadoes rotate in a direction that matches earth's (clockwise in the northern hemisphere and counterclockwise in the southern), a small percentage go against this. The origin of the spin in tornadoes is not directly related to earth's rotation. Most tornadoes also move in an easterly direction, but not always.
Tornadoes can be dangerous to both people and structures on Earth due to their destructive winds and flying debris. However, tornadoes are a natural part of the Earth's weather systems and play a role in redistributing heat and moisture in the atmosphere.
Movement of the Earth's plates does not directly cause tornadoes. Tornadoes are usually formed by the interaction of warm, moist air and cold, dry air in the atmosphere, along with specific weather conditions like thunderstorms. Plate tectonics, which involves the movement of the Earth's crustal plates, occurs within the Earth's lithosphere and is not directly related to tornado formation.
Tornadoes can be devastating to vegetation and man-made structures, but the ground itself is usually not affected in any significant way except in the most violent tornadoes. In rare cases tornadoes can be stroung enough to scour away the soil.
The three most important things for life on Earth are water, the atmosphere (which provides oxygen and regulates temperature), and a stable source of energy (such as sunlight) for photosynthesis and ecosystem functioning.
Tornadoes demonstrate that Earth's atmosphere can hold quite a bit of energy.
Drangonflies are important to life on earth because they eat the mosquitoes which no one likes.
Without the atmosphere, there would be no life on earth.
Outside of tornadoes the strongest winds on earth occur in hurricanes.
Solar energy drives all the processes important to life on Earth.
Yes!
Tornadoes happen because there is wind on earth!
Oxygen is important as it the breathing sources. It also forms ozone which is vital for life on earth.
sand dunes important in tornadoes as when the tornadoes come the high pressure wind take it to the direction where the wind is blowing
yes
It is important in case there is life beyond Earth.
Yes because God put them on Earth and created them for a specific reason. But, really, nobody knows. Just like "Are mosquitoes important to life on earth?"
