SOL 5.7 Plate Mvmt.

Castel Plate boundaries

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.
