Question

which terms describe space objects that are small chunks of rock and debris that are smaller than 1 km? select three options
meteoroids
asteroids
meteors
meteorites
comets

Explanation:

• Meteoroids are small chunks of rock and debris in space.
• When meteoroids enter Earth's atmosphere and burn up, they are called meteors.
• Meteorites are meteoroids that survive the passage through the atmosphere and land on Earth.
• Asteroids are larger (usually more than 1 km in diameter, though some can be smaller but the key here is the description of small chunks as per the question's context where meteor - related terms fit better for the'small chunks' under 1 km as per common astronomical definitions in basic learning). Comets have a different structure (icy nucleus, etc.) and are not just small rock/debris chunks in the sense described here.

Answer:

meteoroids, meteors, meteorites
