Question

a shooting star is formed when a _________ burns up in earths atmosphere. star meteor asteroid

Explanation:

A shooting star (meteor) is the visible streak of light from a meteoroid burning up in Earth's atmosphere. A star is a massive celestial body, not burning in Earth's atmosphere. An asteroid is a rocky body in space, and when it enters the atmosphere, the part burning is a meteoroid (becoming a meteor). So the correct term for the object burning in the atmosphere to form a shooting star is "Meteor".

Answer:

Meteor (the option with "Meteor" as the text, assuming the checkbox next to it is to be selected; if it's a multiple - choice with options labeled, e.g., if the options are labeled as:
A. Star
B. Meteor
C. Asteroid
Then the answer is B. Meteor)
