Question:
Which of the following best explains the term "continental shield"?
Which of the following best explains the term "continental shield"?
Show Hint
Continental shields = oldest rocks on Earth, stable and mostly Precambrian in age.
Updated On: Jun 16, 2025
- Submarine ridges with high heat flow
- Oceanic crust covered by continental sediments
- Large regions of exposed Precambrian crystalline igneous and metamorphic rocks
- Young mountain ranges formed by recent tectonic activity
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Continental shields are ancient, stable parts of the continental lithosphere composed mainly of Precambrian igneous and metamorphic rocks. These areas have remained tectonically inactive for billions of years and form the geological cores of continents.
