Theory of Plate Tectonics
Plate boundaries are locations where tectonic plates meet. Based on their movement, they are classified into three types.
Divergent boundaries occur when plates move apart, convergent boundaries form when plates move toward each other, and transform boundaries involve plates moving horizontally past each other.
Most geological activities, such as volcanoes, earthquakes, and mountain building, occur at these boundaries.
The theory of plate tectonics unifies many of Earth’s surface features and processes. It explains that the shape of the Earth’s surface changes over time as plates move.
For example, mountains form when two plates collide and push land upward.
Earthquakes often occur at transform and convergent boundaries due to the intense friction and pressure between plates.
Volcanoes form where plates diverge, allowing magma to rise, or where one plate subducts beneath another.
Many valuable minerals and resources are located near these geologically active regions.
Plate movements also explain why similar fossils are found on continents now separated by oceans.
Some edges of continents are active with earthquakes and volcanoes, while others are calm and stable.
