Question

1. which best describes a meteor?

burn when they strike earths atmosphere, leaving bright streak
short and long - period orbits, composed of ice and rocks
thousands orbit the sun between mars and jupiter
made of ice that vaporizes in a long visible tail when close to the sun

Explanation:

A meteor is the visible streak of light from a small celestial body (meteoroid) burning up as it enters Earth's atmosphere due to friction. The first option matches this definition. The second describes comets (ice/rock with orbits), the third describes asteroids (between Mars and Jupiter), and the fourth describes comets (ice vaporizing into a tail).

Answer:

burn when they strike Earth's atmosphere, leaving bright streak
