Rock Cycle
This rock type forms form cooled magma or lava.
What is igneous rock?
Preserved remains of organisms found in rock.
What are fossils?
Earth’s outer layer is broken into these moving pieces.
What are tectonic plates?
A slow change that shapes Earth's surface over time.
What is erosion or weathering?
Why are fossils rarely found in igneous rock?
Because heat destroys organisms
Breaking rocks into smaller pieces is called this process.
What is weathering?
According to rock layers, the oldest layers are found here.
Where is the bottom?
Plates that move apart form this boundary.
What is a divergent boundary?
A rapid change caused by sudden energy release in Earth's crust.
What is an earthquakes?
How does plate movement support the idea Earth changes over time?
Heat and pressure change rock into this type.
What is metamorphic rock?
Identical fossils found on different continents suggest this.
What is continents were once connected?
This boundary causes earthquakes when plates slide past each other.
What is a transform boundary?
This occurs when melted rock reaches Earth's surface.
What is a volcanic eruption?
A scientist finds marine fossils on a mountain. What does it suggest?
This process moves sediments from one place to another.
What is erosion?
This type of evidence includes rock layers and fossils.
What is physical evidence?
This boundary forms mountains when plates collide.
What is a convergent boundary?
This is landform is created when tectonic plates collide.
What is a mountain?
Why is Earth's surface constantly changing?
Because of internal forces (plates) and external forces (weathering/erosion)
This rock type forms form compacted and cemented sediments.
What is sedimentary rock?
Finding marine fossils on mountains suggests this past environment.
What is the area was once underwater?
Name TWO events caused by plate movement.
What are earthquakes, volcanoes, mountain building?
Explain the difference between slow and rapid Earth changes
Slow = gradual (erosion, weathering); Rapid = Sudden (earthquakes, volcanoes)
Explain how both rock layers and plate tectonics support Earth's evolution.
Rock layers show history over time; plate movement explains how changes occur
