Understanding Plate Tectonics
Plate tectonics is the scientific theory that explains the structure and motion of the Earth’s lithosphere, which is divided into several large and small plates. These tectonic plates float on the semi-fluid asthenosphere beneath them and interact at their boundaries, leading to various geological activities.
The Basics of Plate Tectonics
1. Lithosphere and Asthenosphere:
- Lithosphere: The rigid outer layer of the Earth, approximately 100 kilometers thick, composed of the crust and the upper mantle.
- Asthenosphere: The semi-fluid layer beneath the lithosphere that allows tectonic plates to move.
2. Types of Plate Boundaries:
- Convergent Boundaries: Plates collide, leading to subduction or mountain formation.
- Divergent Boundaries: Plates move apart, resulting in new crust formation, often seen at mid-ocean ridges.
- Transform Boundaries: Plates slide past one another, causing earthquakes along faults.
3. Plate Movement: Tectonic plates move due to convection currents in the mantle, driven by heat from the Earth’s core. This movement can be slow, at rates of a few centimeters per year.

Common Questions and Answers from the Gizmo
- What happens at a convergent boundary?
- Plates collide, leading to either subduction (one plate sliding beneath another) or mountain building.
- How do divergent boundaries create new crust?
- As plates pull apart, magma rises from below the Earth’s surface, solidifying to form new crust.
- What geological features are formed at transform boundaries?
- Transform boundaries often result in faults, which can lead to significant earthquake activity.
