Tornadoes are given intensity ratings on the Enhanced Fujita Scale ranging from EF0 (weakest) to EF5 (strongest). These ratings are assigned based on damage which is used to estimate wind speed.
EF0, 65-85 mph: minor roof damage, downed gutters and awnings, tree limbs broken, weak-rooted trees toppled.
EF1, 86-110 mph: severe roof damage to houses, trailers badly damaged and overturned, windows broken, garages and porches collapse.
EF2, 111-135 mph: roofs mostly or completely removed from houses, trailers completely destroyed.
EF3, 136-165 mph: significant number of walls collapse in houses, most trees in a forest uprooted.
EF4, 166-200 mph: well-built houses completely collapse, trees stripped of bark and only stubs of largest branches remain.
EF5, over 200 mph: well-built houses disintegrate and are swept away, foundations left bare.
A number of informal terms exist for describing the shape of a tornado including rope (a thin funnel often seen in dissipating tornadoes), elephant trunk (classic tornado shape), cone (self explanatory), stovepipe (a vertical column), and wedge (appears wider than the height of the clouds).

What are the different types of shadows and how do they vary in terms of size, shape, and intensity?
There are three main types of shadows: umbra, penumbra, and antumbra. The size of a shadow depends on the distance between the object casting the shadow and the surface it falls on. The shape of a shadow is determined by the shape of the object casting it. The intensity of a shadow is influenced by the angle of the light source and the transparency of the object casting the shadow.
How skinny can a tornado be at the ground?
Tornadoes can vary in width, but the narrowest tornadoes can be as thin as a few meters at the ground. These thin tornadoes are often referred to as rope tornadoes because of their slender and elongated shape.
What causes in the change in the intensity of a sound?
The intensity of a sound is affected by the amplitude of the sound wave, which is how high or low the waves are. A change in the distance from the sound source, the medium through which the sound travels, or any obstructions in the path can also affect the intensity of the sound. Additionally, factors like the size and shape of the space where the sound is heard can impact its intensity.
What is the object shadow?
An object shadow is a dark area created on a surface when light is blocked by an object placed in its path. The size and shape of the shadow depend on the angle and intensity of the light source, as well as the distance between the object and the surface.
What scientific question can you ask about light and shadows?
How does the angle and intensity of light affect the size and shape of shadows cast by objects?
What shape is the tornadoes?
Tornadoes are generally funnel or cone shaped.
Do Tornadoes change shape?
Yes, tornadoes often change in appearance.
Can tornadoes shape the land?
Not really. Tornadoes can cause some soil erosion and, in rare cases, ground scouring, but overall they have very little effect on the shape of the land.
How flowers differ?
They differ in shape ,size and even colour

How do tornadoes shape the earths surface?
Tornadoes can shape the Earth's surface by creating paths of destruction through their high winds and intense pressure changes. They can uproot trees, strip vegetation, and even move large objects. This can lead to changes in the landscape and patterns of erosion.
Are all tornadoes spiral?
Tornadoes generally don't have a spiral shape. But the winds in and near a tornado always move in a spiral pattern.
Why do tornadoes have a spiral shape?
Tornadoes have a spiral shape due to the rotation of air within the thunderstorm that forms them. The rotation creates a horizontal spinning effect in the atmosphere which, when combined with updrafts and atmospheric conditions, can cause the rotating column of air to stretch vertically and form a tornado with a spiral shape.
