Rock Cycle Basics
This type of rock forms from cooled magma or lava.
What is igneous rock?
Rock formed from layers of sediment.
What is sedimentary rock?
Earth’s outer solid layer broken into moving pieces.
What is the lithosphere?
Plates moving apart form this boundary.
What is divergent boundary?
Shaking of the ground from plate movement.
What is an earthquake?
The process where sediments are pressed and glued together.
What is compaction and cementation?
Example of an igneous rock that cools underground slowly.
What is granite?
These move slowly on the mantle and cause earthquakes.
What are tectonic plates?
Plates colliding form this boundary.
What is convergent boundary?
Mountains form when these plates collide.
What are continental plates?
Heat and pressure change this rock type into metamorphic rock.
What is any existing rock?
This rock may contain fossils.
What is sedimentary rock?
The theory explaining movement of Earth’s plates.
What is plate tectonic theory?
Plates sliding past each other form this boundary.
What is transform boundary?
Volcanoes often form at this type of boundary with subduction.
What is a convergent boundary?
Molten rock below Earth’s surface is called this.
What is magma?
Rock changed by heat and pressure but not melted.
What is metamorphic rock?
The supercontinent that existed millions of years ago.
What is Pangaea?
Ocean crust sinks beneath continental crust at this zone.
What is subduction zone?
This causes continents to slowly move over time.
What is plate motion / mantle convection?
This process breaks rocks into smaller pieces without moving them.
What is weathering?
This texture forms when lava cools very quickly.
What is glassy texture (obsidian)?
The layer beneath the lithosphere that flows slowly.
What is the asthenosphere?
New ocean crust forms at this feature.
What is mid-ocean ridge?
The Ring of Fire surrounds this ocean.
The Ring of Fire surrounds this ocean.
