How do tectonic plates shape Earth's geography and landscapes?

Tectonic plates are massive sections of Earth's lithosphere that move and interact at their boundaries. This movement leads to significant geographical changes. Here are some key insights:

Key Facts

• Earth's lithosphere is divided into about 15 major tectonic plates.
• The movement of these plates is driven by convection currents in the mantle.
• Plate interactions can create mountains, rift valleys, and ocean trenches.
• Approximately 90% of earthquakes occur at plate boundaries.

Examples or Use Cases

• The Himalayas were formed by the collision of the Indian and Eurasian plates.
• The San Andreas Fault in California exemplifies transform boundaries, leading to frequent seismic activity.

FAQs

• What happens when tectonic plates move? Tectonic plate movement can cause earthquakes, volcanic eruptions, and the creation of new landforms.
• How often do tectonic plates move? Plates move at a rate of a few centimeters per year, similar to the growth of human fingernails.
