Comets are cosmic snowballs of frozen gases, rock and dust that orbit the Sun. When frozen, they are the size of a small town. When a comet's orbit brings it close to the Sun, it heats up and spews dust and gases into a giant glowing head larger than most planets.Comet nuclei are loose collections of ice, dust and small rocky particles, ranging from a few kilometers to tens of kilometers across. As a comet approaches the inner solar system, solar radiation causes the volatile materials within the comet to vaporize and stream out of the nucleus, carrying dust away with them. The streams of dust and gas form a huge, extremely tenuous atmosphere around the comet called the coma, and the force exerted on the coma by the radiation pressure of the Sun and solar wind cause a tail to form. The tail always points away from the sun.

Explanation:

Each comet consists of the following:

1) Nucleus, consisting of a stable, porous central mass of ice, gas, and dust. Generally, it will be between 1 - 10 km/0.6 – 6 miles in diameter. The ice contains varying amounts of water, carbon dioxide, ammonia, and methane; the dust may contain various mixtures hydrogen, oxygen, carbon, nitrogen, silica, and some metals; and, traces of hydrocarbons may also be in the nucleus.

2) Coma, which is the visible, cloud-like atmosphere;

3) Dust Tail, which consists of a long, streaming-appearing tail of dust particles reflecting sunlight; and,

hola:

ef0: daños leves. algunas tejas caídas y otras pequeñas piezas de los tejados arrancadas, algunos daños en canaletas, ramas de árboles rotas y algunos árboles poco profundos arrancados. los tornados que no causan daños visibles (por ejemplo aquellos que se producen en campos abiertos) se valoran siempre como de ef0.

ef1: daños moderados. tejados seriamente despedazados, caravanas y casetas volcadas o seriamente dañadas, perdida de puertas exteriores y ventanas y otros cristales rotos.

ef5: daños increíbles. las casas fuertes pueden quedar arrasadas hasta los cimientos, las estructuras de hormigón armado dañadas críticamente, los edificios altos sufren graves deformaciones estructurales. devastaciones increíbles.

y según esto creo que puedes sacar tus conclusiones. y la verdad la escala ef10 si no se decirte por que no la eh visto o mejor dicho estudiado. espero que te sirva. suerte.
