Explanation:

Question 2

Comets are often described as "dirty snowballs." Their typical composition includes ice (water ice, and other ices like carbon dioxide, ammonia), dust (small solid particles), rock (solid mineral particles), and frozen gases (like methane, carbon monoxide). Option a has salt and carbon which are not typical main components. Option b has magma which is not a component of comets. Option d has soil which is not a comet component. Option c lists ice, dust, rock, frozen gases which matches the known composition.

Comets originate from the Oort cloud (a spherical cloud of icy bodies far from the Sun) or the Kuiper belt (a region of icy objects beyond Neptune). Their orbits are highly elliptical (long - elliptical), taking them from the outer solar system close to the Sun and back out. Option a: The region between Mars and Jupiter is the asteroid belt, not a comet origin. Option b: Comet orbits are not circular like planets. Option c: Comets are from our solar system, not another galaxy. Option d correctly states the origin (Oort cloud or Kuiper belt) and orbit (long - elliptical).

A "shooting star" is actually a meteor (the streak of light from a space object burning up in the atmosphere). If it hits the ground, it's a meteorite. The objects made of ice and dust orbiting the Sun are comets, and they can also break off from an asteroid (though the text seems to have a typo, likely "asteroid" here as asteroids are small, irregularly shaped objects, many in the asteroid belt).

Answer:

c. Ice, dust, rock, frozen gases
