Question:
Which one of the following is an undifferentiated meteorite?
Which one of the following is an undifferentiated meteorite?
Show Hint
Undifferentiated meteorites have not undergone melting and separation into layers, unlike differentiated meteorites like basaltic achondrites and eucrites.
Updated On: Sep 6, 2025
- Basaltic achondrite
- Carbonaceous chondrite
- Eucrite
- Pallasite
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
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: \[ \boxed{\text{Carbonaceous chondrite}} \]
