Study Notes
Earth's Interior
- Tectonic plates float on the Asthenosphere, the upper part of the Earth's mantle.
Plate Interactions
- At plate boundaries, plates interact in three different ways:
- Convergent (colliding), where plates move towards each other and can result in subduction or collision.
- Divergent (separating), where plates move apart from each other and new crust is formed.
- Transform (sliding), where plates slide past each other horizontally.
Plate Separation
- The driving force behind the separation of plates at constructive or divergent boundaries is convection currents in the Earth's mantle.
Rock Formation
- Igneous rock is formed when magma rises to the surface and cools and solidifies.
Mid-Atlantic Ridge
- The Mid-Atlantic Ridge is a divergent boundary where the North American and Eurasian plates are moving apart, and new oceanic crust is being created through volcanic activity.
Test your knowledge of plate tectonics with this quiz! Learn about the different ways tectonic plates interact at plate boundaries, including separation, collision, and sliding past one another. Discover the driving forces behind these plate movements and enhance your understanding of Earth's crust.
