Columbia supercontinent hypothesis
E1489980
UNEXPLORED
The Columbia supercontinent hypothesis proposes the existence of one of Earth’s earliest known supercontinents, assembled in the Paleoproterozoic era and later fragmented, helping to explain ancient global tectonic and orogenic patterns.

-
A.
Continental Drift
Continental Drift is a song by The Rolling Stones featured on their 1989 album "Steel Wheels," known for its atmospheric, world music-influenced sound.
-
B.
Gondwana amalgamation
Gondwana amalgamation refers to the late Neoproterozoic–early Paleozoic tectonic assembly of the supercontinent Gondwana through the collision and suturing of multiple continental blocks and terranes.

C.
Wilson cycle of Pangaea assembly
The Wilson cycle of Pangaea assembly refers to the full tectonic life cycle in which ancient oceans opened and later closed through plate convergence, culminating in the formation of the supercontinent Pangaea.
-
D.
supercontinent Pangaea
Pangaea was a massive supercontinent that existed during the late Paleozoic and early Mesozoic eras, when nearly all of Earth's landmasses were joined together before breaking apart into the continents we know today.
-
E.
Neoproterozoic supercontinent cycle
The Neoproterozoic supercontinent cycle refers to the sequence of assembly and breakup of supercontinents during the Neoproterozoic Era, including the formation and fragmentation of Rodinia and the tectonic, climatic, and biological changes associated with these events.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
