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