Weathering/Erosion/Deposition
This is the process where rocks are broken into smaller pieces.
What is weathering?
This type of rock forms when lava or magma cools.
What is igneous rock?
This process turns sediment into sedimentary rock.
What are compaction and cementation?
This scientist proposed continental drift in 1912.
Who is Alfred Wegener?
Fossils found on different continents helped support this theory.
What is continental drift?
This process moves sediment from one location to another.
What is erosion?
This type of rock forms from compacted sediment.
What is sedimentary rock?
This process changes rock into magma.
What is melting?
Plates move at this speed according to the reading.
What is a few centimeters per year?
South America appears to fit with this continent.
What is Africa?
This process happens when sediment is dropped in a new location.
What is deposition?
This type of rock forms through heat and pressure.
What is metamorphic rock?
This process turns magma into igneous rock.
What is cooling?
This boundary forms when plates collide.
What is a convergent boundary?
Scientists use this to explain Earth changing over time.
What is plate tectonics?
Wind, water, and ice are examples of this that move sediment.
What are agents of erosion?
This rock often contains fossils.
What is sedimentary rock?
This changes sedimentary rock into metamorphic rock.
What are heat and pressure?
These mantle movements help plates move.
What are convection currents?
The rock cycle and plate tectonics both explain this.
What is how Earth changes over time?
These processes shape Earth’s surface over time.
What are weathering, erosion, and deposition?
This rock begins as another rock and changes under heat and pressure.
What is metamorphic rock?
These two processes help turn rocks into sediment.
What are weathering and erosion?
Earthquakes, volcanoes, and mountains can form because of this theory.
What is plate tectonics?
W-E-D all work together to shape this.
What is Earth’s surface?
