Plate Tectonics
Rigid, but moving, pieces of Earth's crust and upper mantle.
What are tectonic plates?
The study of Earth: its materials, how it changes, and the processes that shape it.
What is geology?
A solid, natural material found in the ground (ex. Gold).
What is a mineral?
The amount of layers of Earth.
What is four?
These are the three types of plate tectonic boundaries.
What are divergent, convergent, and transform?
Studying these provides clues about Earth's past.
A hard, solid material made up of one or more minerals.
What is a rock?
The thinnest layer of Earth.
What is the crust?
Used as evidence to help prove the continental drift theory.
What is fossil data?
This kind of rock is formed from melted rock cooling and is one of the three most common rock types.
What is igneous rock?
Hot, melted rock found deep underground.
What is magma?
This is the thickest layer of the Earth, and is made of hot, dense, liquid rock we call magma.
What is the mantle?
Two tectonic plates colliding.
What is a convergent boundary?
This type of rock is made of layers of sand, mud, and small pieces of rock pressed together.
What is sedimentary rock?
What is erosion?
These two metals make up a majority of the Earth's outer core.
What is iron and nickel?
When tectonic plates slip past each other.
What is a transform boundary?
This type of rock has changed its form from heat or pressure.
What is metamorphic rock?
When rocks break down into smaller pieces.
What is weathering?
The scientific name for the Earth's crust.
What is the lithosphere
