What role do tectonic plates play in shaping geography?.

Tectonic plates are massive sections of the Earth's lithosphere that move and interact at their boundaries, significantly influencing geographical formations. Here are some key aspects of their role:

Key Facts

• The Earth's lithosphere consists of about 15 major tectonic plates.
• Movement of plates can cause earthquakes; approximately 80% of the world's earthquakes occur along plate boundaries.
• Mountain ranges, such as the Himalayas, formed due to the collision of tectonic plates.
• The theory of plate tectonics was developed in the 1960s, revolutionizing our understanding of geological processes.

Examples or Use Cases

• The Pacific Plate's movement is responsible for the volcanic activity in the Ring of Fire.
• The Mid-Atlantic Ridge is a divergent boundary where new oceanic crust is formed, shaping the Atlantic Ocean's geography.

FAQs

• How do tectonic plates affect natural disasters? Tectonic movements can trigger earthquakes, tsunamis, and volcanic eruptions, impacting human life and infrastructure.
• What is continental drift? Continental drift is the movement of continents over geological time due to tectonic plate movements.
