Earth's Structure
The layer of Earth that we live in/on.
What is the Crust?
The name of the theory describing Earth's crust as a puzzle of interlocked pieces.
What is the Theory of Plate Tectonics?
The type of plate boundary where two plates move towards each other.
What is a Convergent Boundary?
The region on Earth's surface most notable for its active subduction zones, fueling volcanoes, earthquakes, and tsunamis alike?
What is the Ring of Fire?
The layer of Earth that is made of semi-solid, semi-liquid rock.
What is the Mantle?
The type of fluid thermal transfer that fuels movements in Earth's crust.
What is Convection?
The type of plate boundary where two plates move away from one another.
What is a Divergent Boundary?
What is formed when water from subducted oceanic plate is released into the Mantle, lowering the melting point of the surrounding rock.
What is a Magma Plume?
The layer of Earth made almost exclusively of iron.
What is the Core?
The name of the zones where tectonic plates meet.
What is a Plate Boundary?
The type of plate boundary where the plates move past each other; known for frequent, but weaker earthquakes.
What is a Transform Boundary?
The type of volcano known for its explosiveness due to high-silica magma.
What is a Stratovolcano?
The layer of Earth made up of continental and oceanic plates.
What is the Crust?
What we call deformations of Earth's surface, caused by interactions at plate boundaries.
What are Landforms?
The type of plate boundary where new crust is formed, and where undersea vents are common.
What is a Divergent Boundary?
The type of volcano that forms due to low-silica magma, most known for island formation.
What is a Shield Volcano?
What geologists refer to the Crust and Upper Mantle by, because it is all that humanity can currently observe/interact with.
What is the Lithosphere?
The names of the two types of plate, sitting underneath the ocean and forming land, respectively?
What are Oceanic and Continental Plate?
The type of convergent boundary where one plate slides into the mantle, underneath the other plate?
What is a Subduction Zone?
The plate boundary where the Ring of Fire exists.
What is the Pacific Plate Boundary?
