The Wilson Cycle Flashcards and Quizzes

Module 1: Core Concepts and Definitions

The Wilson Cycle is a comprehensive geological model introduced by J. Tuzo Wilson in 1966, illustrating the dynamic processes behind the formation, evolution, and closure of ocean basins. Understanding the Wilson Cycle is crucial for grasping fundamental concepts in geology and plate tectonics.

Core Stages of the Wilson Cycle

• Rifting: This initial stage involves tectonic plates diverging, which ultimately leads to the formation of new ocean basins.
• Seafloor Spreading: Occurs along mid-ocean ridges where molten lava rises to create new oceanic crust.
• Ocean Basin Formation: As tectonic activities progress, the ocean basin widens, marked by increased geological activity.
• Subduction: Here, one tectonic plate sinks beneath another, facilitating the destruction of oceanic crust and the recycling of materials into the mantle.
• Continental Collisions: The convergence of tectonic plates eventually leads to mountain formation as the continental crust is compressed.

Overall, the Wilson Cycle explains the continuous and interconnected mechanisms driving the geological evolution of our planet.
