Question

Which one of the following is an undifferentiated meteorite?

• A. Basaltic achondrite
• B. Carbonaceous chondrite
• C. Eucrite
• D. Pallasite

Hint:

Undifferentiated meteorites have not undergone melting and separation into layers, unlike differentiated meteorites like basaltic achondrites and eucrites.

Answer 1

The Correct Option is B

Step 1: Understand Undifferentiated Meteorites.
Undifferentiated meteorites are those that have not undergone differentiation, meaning their components have not separated into distinct layers (such as core, mantle, and crust).
Step 2: Identify the Correct Meteorite Type.
- Basaltic achondrite is a type of differentiated meteorite.
- Carbonaceous chondrite is an undifferentiated meteorite that has not undergone significant alteration.
- Eucrite is a differentiated meteorite type.
- Pallasite is a type of differentiated meteorite, containing both silicate minerals and iron-nickel metal.
Thus, the correct answer is Carbonaceous chondrite. Final Answer: \[ \boxed{\text{Carbonaceous chondrite}} \]
