Top layer of Earth, the one we live on.
What is the crust?
Boundary where two plates are moving towards each other.
What is a Convergent boundary?
Created the Continental Drift theory.
Who is Alfred Wegener?
Fracture between two blocks of rock.
What is a fault?
The more dense type of crust.
What is oceanic crust?
Mostly solid rock layer of Earth, largest layer.
What is the Mantle?
Boundary where two plates are moving from each other.
What is a Divergent boundary?
Amount of major tectonic plates.
What is 8?
When new crust is formed at a mid-oceanic ridge.
What is sea-floor spreading?
Type of convergent boundary that forms mountains.
What is continental/continental?
Liquid layer of Earth, made of iron and nickel.
What is the outer core?
Boundary where plates slide past each other.
What is a Transform boundary?
All of Earth's continents as one, a supercontinent.
What is Pangea?
When enough friction builds on a transform boundary, that it can be released as shaking of the ground.
What is an Earthquake?
A major volcanic zone which is found along the Pacific ocean and travels all the way from South America to North America and along Asia.
What is the Pacific Ring of Fire?
Solid layer of Earth, innermost layer.
What is the inner core?
When a plate slips under another, sometimes forming volcanoes.
What is a subduction zone?
Vast, underwater mountain ranges.
What are Deep-sea trenches?
When lava spews out of a volcano also has dangerous gases.
What is a volcanic eruption?
The transfer of thermal energy by the circulation or movement of a gas or liquid.
What are convection currents?
Consist of the crust and the upper mantle.
What is the lithosphere?
Where new crust is formed.
What is a mid-oceanic ridge?
Theory that explains the structure of earths crust.
What are plate tectonics?
Molten rock inside the earth.
What is Magma?
Is the layer of the upper mantle composed of low-density rock.
What is the asthenosophere?
