Tectonic plates 2022
Map of Earth's 16 main tectonic plates. It shows how the plates meet:
Divergent:
  Where plates pull apart
  Areas stretching apart
Convergent:
  Where one plate slides under another
  Where plates crash together
Transform:
  Plates sliding past each other (right)
  Plates sliding past each other (left)

Our Earth's surface is not one solid piece. Instead, it's like a giant puzzle made of huge, moving pieces called tectonic plates. These plates are made of the Earth's crust and the very top part of the Earth's mantle, which together are called the lithosphere.

These plates are about 100 kilometers (60 miles) thick. They are made of two main types of material: oceanic crust (found under oceans) and continental crust (which makes up the land we live on). Oceanic crust is mostly made of heavy, dark rocks like basalt. Continental crust is lighter and made of rocks like granite.

Current Tectonic Plates

Scientists agree that there are many tectonic plates moving on Earth today. These plates have boundaries that can be mapped. Tectonic plates are often put into three groups based on their size: major plates, minor plates, and microplates.

Major Plates

A detailed map showing Earth's main tectonic plates and their boundaries.

These are the biggest plates. They make up most of the continents and the Pacific Ocean. For this list, a major plate is any plate larger than 20 million square kilometers.

Minor Plates

These plates are smaller and often not shown on maps of the major plates. Most of them don't cover large land areas. For this list, a minor plate is smaller than 20 million km2 but larger than 1 million km2.

  • Amurian Plate
  • Arabian Plate – 5,000,000 km2
  • Burma Plate – 1,100,000 km2
  • Caribbean Plate – 3,300,000 km2
  • Caroline Plate – 1,700,000 km2
  • Cocos Plate – 2,900,000 km2
  • Indian Plate – 11,900,000 km2
  • Nazca Plate – 15,600,000 km2
  • New Hebrides Plate – 1,100,000 km2
  • Okhotsk Plate
  • Philippine Sea Plate – 5,500,000 km2
  • Scotia Plate – 1,600,000 km2
  • Somali Plate – 16,700,000 km2
  • Sunda Plate
  • Yangtze Plate

Microplates

Microplates are the smallest plates, usually less than 1 million km2. They are often considered part of a larger nearby plate. Newer studies suggest that even larger plates are made up of many tiny microplates. Some scientists have identified about 1200 of these smaller pieces.

A new map of Earth's plates, showing about 1200 smaller plates across continents, oceans, and mountain ranges. Green shows microplate borders in continents. Cyan shows microplates in oceans. Orange shows microplates in mountain belts. Blue lines are ocean faults. Red lines are faults in continents and mountains. Purple lines are main subduction and collision zones. Orange dots are volcanoes.

Ancient Tectonic Plates

Over Earth's long history, many tectonic plates have formed and then disappeared. They might have joined with other plates to make bigger ones, split into smaller pieces, or been pushed under other plates.

Below is a list of ancient cratons, microplates, and terranes that no longer exist as separate plates. Cratons are very old and strong parts of continents. Shields are parts of cratons that are exposed at the surface. Terranes are pieces of crust that broke off one plate and attached to another.
