Multiple Choice

Which statement best describes the difference between a meteor and a meteorite?

A meteor is the streak of light produced when a meteoroid enters Earth's atmosphere, while a meteorite is a fragment that survives and lands on Earth's surface.

A meteor is a small planet, while a meteorite is a large asteroid.

A meteor is a gaseous cloud in space, while a meteorite is a solid piece of ice.

A meteor is a type of rock found only in space, while a meteorite is a type of rock found only on the Moon.

Verified step by step guidance

Step 1: Understand the terminology related to space objects entering Earth's atmosphere. A meteoroid is a small rocky or metallic body traveling through space.

Step 2: When a meteoroid enters Earth's atmosphere and burns up due to friction with air, it produces a visible streak of light called a meteor (often referred to as a 'shooting star').

Step 3: If any part of the meteoroid survives its passage through the atmosphere and lands on Earth's surface, that surviving fragment is called a meteorite.

Step 4: Differentiate between the terms by focusing on their physical state and location: a meteor is the luminous phenomenon in the atmosphere, while a meteorite is the solid object found on the ground.

Step 5: Use this understanding to evaluate the given statements and identify the one that correctly describes the difference between a meteor and a meteorite.
