- What is plate tectonics?
Show answer
The theory that Earth's crust is divided into plates that move and interact- How many major tectonic plates make up Earth's crust?
Show answer
About 7 major plates (sometimes counted as 8)- What are the three main types of plate boundaries?
Show answer
Divergent, convergent, and transform- What happens at a divergent plate boundary?
Show answer
Two plates move apart and new oceanic crust forms- What happens at a convergent plate boundary?
Show answer
Two plates collide or move toward each other- What happens at a transform plate boundary?
Show answer
Two plates slide horizontally past each other- What is the Mid-Ocean Ridge?
Show answer
An underwater mountain range where new oceanic crust forms at divergent boundaries- What landforms typically result when two continental plates collide?
Show answer
Mountains- What is magma?
Show answer
Molten (melted) rock found inside the Earth- What is lava?
Show answer
Magma that has erupted onto Earth's surface- What causes earthquakes?
Show answer
The sudden movement and release of energy from tectonic plates- What is a volcano?
Show answer
An opening in Earth's crust where molten rock, ash, and gases erupt- What force drives the movement of tectonic plates?
Show answer
Heat from Earth's interior and convection currents in the mantle- What is the name of the layer below Earth's crust?
Show answer
The mantle- Is oceanic crust or continental crust denser?
Show answer
Oceanic crust is denser
