Final answer:
The tail of a comet is made up of dust and gas. The dust tail is composed of fine dust particles, while the ion tail contains ionized gas swept away by the solar wind.
Correct Option is; dust and gas
Step-by-step explanation:
The tail of a comet can consist of dust and gas. Notably, comets have two types of tails, each composed of different materials. The dust tail, which is typically more visible, contains fine particles similar in size to smoke particles.
The light from the Sun reflects off these particles, pushing them away, and causing the tail to have a curved shape. On the other hand, the ion tail, which appears straighter and is fainter, consists of ionized gas.
These ions are generated when solar photons interact with atoms in the comet's material, and they are swept away from the Sun by the solar wind.
A comet's tail consists of two main components: a dust tail and an ion tail. The dust tail is made up of small dust particles that are loosened by the sublimation of ice in the comet and are pushed away from the Sun by the scattering of photons.
The ion tail is composed of ionized gas particles that are swept away from the Sun by the solar wind. Both tails always point away from the Sun due to the interaction with solar radiation.
