Plates

There was once a time when you could take a stroll from North or South America to Africa no problem!

Plate tectonics theorizes that Earth's outer layer is made up of large, moving pieces called plates! These plates are in constant motion.

The Himalayan mountains formed as the Indian plate crashed into the Eurasian plate.

That's 1-6 inches a year!

• Heat rises at spreading centers, pushing plates apart

• This process resulted in the breakup of Pangea, the formation of the Atlantic Ocean, and how Earth's surface appears today!

• Subduction Zone

• Mid - Ocean Ridge (Seafloor Spreading)

• Hot Spots

The Himalayan mountains formed as the Indian plate crashed into the Eurasian plate.

• Oceanic Pushes Under Continental

• Subduction Zone

• Juan de Fuca Plate Subducts North American Plate

• Cascade Mountain Range

• Pacific & Philippine Plates Subduct Eurasian Plate

• Tallest Mountain in Japan

• Hot Magma Burns a Hole in the Plate

• Creates an Opening for Magma to Escape to Earth's Surface

• Hot Plume of Magma Burns Hole in Crust

• Magma Rises and Hardens Into New Rock

• Plate Moves and Another Hole is Burned

• Reason for Chain of Islands

• Plume of Hot Magma Under Crust

• Last Eruption Formed Large Caldera

• Series of Calderas from Movement of Plate

• Plates Pull Apart

• Magma Rises Between the Plates and Hardens into New Rock

• Mid-Ocean Ridges - Seafloor Spreading

• Rifts - Valleys Dotted with Volcanoes

• Underwater Volcanoes Where Plates Pull Apart

• Add New Land to Ocean Floor

• Plates Continue to Spread - Seafloor Spreading

• Plates Pull Apart on Land

• Creates Valleys Dotted with Volcanoes
