Rocks and the Rock Cycle
The process in which igneous, sedimentary, and metamorphic rocks are converted into one another in stages is called the ?
What is the rock cycle
Categorize: fast/slow or local/global
Landslide
fast and local
What are the layers of the earth?
crust, mantle, inner core, outer core \
What best describes divergent boundaries?
When plates move away from each other
What is the geologic time scale?
The geologic time scale is a timeline of Earth’s history based on evidence from rocks and fossils.
True/false
all rocks has the possibility of becoming another rock
True
Categorize: fast/slow or local/global
volcanic eruption
fast and both local and global
What was the name given to the supercontinent?
What is Pangea?
What causes tectonic plates to move?
Convection currents in the mantle

Earthquakes are not uncommon along the San Andreas Fault. What kind of boundary is found in that area?
Transform Boundaries
Plates slide past each which may cause earthquakes along faults.
What type of fossils help to identify the age of fossils?
Index fossils
According to the rock cycle, how are igneous rocks formed?
when molten rocks cool and crystallises
Categorize: fast/slow or local/global
Erosion of Canyon
Double Jeopardy
slow and local (can be regional)
What are the evidences that scientists suggest that the continents were all one super continent (Pangaea)
Double jeopardy
- the shape of continents fitting together.
- similar fossils on the different continents
- rock evidence (mountains and glacial evidence)
New ocean floor is continuously being produced through process known as _________
What boundary does this happen at?
Seafloor Spreading, divergent boundary
Check out the picture on the board.
Identify the layer that has the oldest fossil.
Layer D
What are the steps to creating a sedimentary rock?
(Double Jeopardy)
What are:
1. Weathering
2. Erosion
3. Deposition
4. Compaction
5. Cementation
Categorize: fast/slow or local/global
Continental Drift
slow and global
Draw what happens at convergent boundary and name one landform/activity that happens at the plate boundary
Double jeopardy
check the board and the teacher will verify.
If an earthquake flipped the layers of a rock, what could you do to recognize which layer is the oldest or the youngest?
Check the fossils.
