What is the geological time frame for the formation of Colombia?

1. 600 million years ago

2. 1.8 billion years ago

3. 300 million years ago

4. 3 billion years ago

The correct answer is: 1.8 billion years ago

The geological formation of Colombia primarily began during the Precambrian era, approximately 1.8 billion years ago. At this time, the region that is now Colombia underwent significant geological processes that contributed to the formation of its diverse rock sequences. The area was influenced by tectonic activity and continental collision, which were crucial in shaping the Andes mountains and the overall geology of Colombia. During this formative period, the landmass that would become Colombia was part of larger supercontinents and went through various phases of sedimentation, volcanic activity, and metamorphism. This long history of geological evolution has resulted in the rich and varied geology that characterizes Colombia today. Understanding this timeline provides insight into the significant geological events that have shaped not only Colombia but also other regions of South America throughout Earth's history.
