Castel Plate boundaries
Term | Definition |
---|---|
Scientific evidence indicates Earth is ancient — approximately | 4.6 billion years old. |
Fossils provide | information about life and conditions of the past. |
Earth’s thermal energy causes | movement of material within Earth. |
Large continent-size blocks are called | plates |
Most earthquakes and volcanoes are located at | the boundaries of the plates (faults). |
Plates can move together | convergent boundaries |
Plates can move apart | divergent boundaries |
Plates can slip past each other horizontally | transform boundaries, also called strike-slip or sliding boundaries |
Geological features in the oceans (including trenches and mid-ocean ridges) and on the continents (mountain ranges, including the Appalachian Mountains) are caused by | current and past plate movements. |
Ring of Fire | The area of tectonic plates with the most amount of active volcanoes in the world. |
Mountains | These are formed when two convergent plates come together and force land to move upward. |
Lava | This is magma outside of the Earth. |
Pangaea | This is the theory of a "super continent", when the Earth was a single landmass. |
Mariana Trench | This is the deepest valley in the world, deep in the Pacific Ocean. |
Earthquakes | Caused by shifting of tectonic plates. |
Transform Faults | Their movement causes earthquakes. |
Trenches | When convergent plates come together and push downward, these form. |
Mountains | When convergent plates come together and push upward, these form. |
Mid-ocean ridges | When divergent plates come apart, and magma seeps up, forming new crust. |
faults | These are the boundary lines between tectonic plates. |
