Plate Tectonics Overview
Plate tectonics is the theory that Earth’s lithosphere, which is the outermost layer of the planet, is divided into several rigid tectonic plates that move relative to each other.
These plates are composed of the crust and the uppermost mantle and are constantly moving due to convection currents in the Earth’s mantle.
Types of Plate Boundaries
- Convergent boundaries:When two plates collide, one plate is forced beneath the other in a process called subduction.
- Divergent boundaries:When two plates move away from each other, new crust is formed in the gap between them.
- Transform boundaries:When two plates slide past each other horizontally.
Major Tectonic Plates
- North American Plate:Covers North America, Greenland, and part of the Atlantic Ocean.
- South American Plate:Covers South America and part of the Atlantic Ocean.
- Eurasian Plate:Covers Europe, Asia, and part of the Arctic Ocean.
- African Plate:Covers Africa and part of the Atlantic Ocean.
- Antarctic Plate:Covers Antarctica and the surrounding ocean.
Key Terms and Concepts
Subduction
The process by which one tectonic plate moves beneath another, typically at a convergent boundary.
Collision
The process by which two tectonic plates collide, resulting in the formation of mountains or other geological features.
Transform Boundaries
The boundaries between tectonic plates that slide past each other horizontally, causing earthquakes and other geological activity.
Role of Plate Tectonics
Plate tectonics is responsible for shaping Earth’s surface features, including mountains, volcanoes, and ocean basins.
Evidence for Plate Tectonics
- Matching rock formations:Similar rock formations are found on different continents, suggesting that they were once part of the same plate.
- Fossil distribution:Fossils of the same species are found on different continents, suggesting that the continents were once connected.
- Magnetic stripes:The ocean floor is covered in alternating bands of magnetic material, which are created as new crust is formed at divergent boundaries.

General Inquiries: Plate Tectonics Crossword Answer Key
What is the definition of a tectonic plate?
A tectonic plate is a massive, irregularly shaped slab of solid rock that forms the Earth’s outermost layer.
What are the three main types of plate boundaries?
The three main types of plate boundaries are convergent boundaries, divergent boundaries, and transform boundaries.
What is the theory of plate tectonics?
The theory of plate tectonics states that the Earth’s lithosphere is divided into a number of tectonic plates that move around the globe.
