What do contour lines on a map represent?
Points of equal elevation.
What do closely spaced contour lines indicate?
Steep slopes.
What do widely spaced contour lines represent?
Gentle slopes or flat areas.
What is the definition of an earthquake?
Sudden and violent shaking of the ground caused by movements along faults/volcanic activity.
What are the three main types of rocks?
- Igneous
- Sedimentary
- Metamorphic
What is a cross section in geology?
A diagram that displays a vertical slice through layers of rock.
What does the law of superposition help infer?

What plays a significant role in the formation of river deltas and beaches?
Sediment transport and deposition.
What is the relationship between volcanic activity and tectonic processes?
Volcanic activity is often connected to plate boundaries and hotspots.
