Volcanoe
Magma vs. Lava
Convergent Boundaries
In plate tectonics a convergent boundary also known as a destructive plate boundary, is actively forming region where two or more tectonic plates or fragments of the lithosphere move toward one another and collide.
Divergent boundaries
In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary) is a linear feature that exists between two tectonic plates that are moving away from each other.
Transverse Boundaries
These are two boundaries that slide past each other without colliding. When two plates slide past each other, they form a narrow stretch and indent in the ground.
Fun Fact!
When the plates slide they soon will slip which causes a massive earthquake.
Subduction Zone
A collision between two of the planets tectonic plates, the pieces of crust that slowly move across the surface over millions of years.
Ocean Trenches
A long narrow deep depression in the ocean floor, typically running parallel to a plate boundary and making a subduction zone.
Mid-Ocean Ridges
An underwater mountain range formed by plate tectonics.
Fun Fact!
These ridges grow from magma eruptions from under water volcanoes in which lava gets pushed to the surface and cools which forms a new layer of rock.
Continental Rifts
The movement of earths continents relative to each other, this appearing to drift across the ocean bed.
Fun Fact!
A continental rift in our world is one in Ethopia, seen in the picture before and here.
Volcano
A mountain or hill, having a crater or vent through which lava, rock fragments,hot vapor, and gas which is being or has been erupted from the earths crust.
Fun Fact!
When lave touches water it cools and turns into rock.
Magma vs. Lava
Magma is below the earths surface while lava is when magma comes above earths surface.
