Earth Changes
This process breaks rocks apart over time.
What is weathering?
This rock forms when magma cools underground.
What is intrusive igneous rock?
This process turns solid rock into molten rock.
What is melting?
This theory explains how Earth’s plates move.
What is plate tectonics?
Scientists found these on separate continents.
What are fossils?
This process moves rock pieces and sediment.
What is erosion?
This rock often forms in layers.
What is sedimentary rock?
This process changes magma into igneous rock.
What is cooling?
This scientist proposed continental drift.
Who is Alfred Wegener?
This landform often forms when continental plates collide.
What are mountains?
Rivers drop sediment through this process.
What is deposition?
This rock forms from heat and pressure.
What is metamorphic rock?
These processes help create sediment.
What are weathering and erosion?
This boundary forms when plates move apart.
What is a divergent boundary?
The rock cycle and plate tectonics both explain this.
What is Earth changes over time?
Wind, water, and ice can all cause this type of change.
What is erosion?
This process turns loose sediment into rock.
What are compaction and cementation?
These conditions change sedimentary rock into metamorphic rock.
What are heat and pressure?
This boundary forms when plates slide past one another.
What is a transform boundary?
Earthquakes and volcanoes often happen near these.
What are plate boundaries?
These three processes shape Earth over time.
What are weathering, erosion, and deposition?
This rock type can form from any existing rock under enough heat and pressure.
What is metamorphic rock?
This cycle explains how rocks are constantly changing.
What is the rock cycle?
These currents in Earth’s mantle move plates.
What are convection currents?
These plate boundaries cause earthquakes and fault lines.
What are transform plate boundaries?
