Slide 15 - Sleepvraag
Weathering and erosion play crucial roles in the rock cycle.
Agree: They break down and transport rocks.
Disagree: Their impact is minimal.
Agree: They sculpt and reshape landscapes.
Disagree: Their effects are overestimated.
Slide 16 - Poll
The rock cycle is a never-ending process of rock formation and transformation.
Agree: It's a continuous natural process.
Disagree: It's a one-time event.
Agree: It's a cycle of constant change.
Disagree: It's a static geological concept.
Slide 17 - Poll
Metamorphic rocks are formed from the alteration of existing rock types under high heat and pressure.
Agree: It's a fundamental process.
Disagree: Their formation is random.
Agree: It's a result of intense geological forces.
Disagree: Their formation is purely chemical.
Slide 18 - Poll
Human activity has the potential to disrupt the natural processes of the rock cycle.
Agree: Activities like mining impact it.
Disagree: It's resilient to human influence.
Agree: Pollution can alter rock formation.
Disagree: Human actions are insignificant in this context.
Slide 19 - Poll
Describe the rock cycle and all its stages in your own words - you can use previous slides to help.
Slide 20 - Open vraag
Why are fossils not found in igneous or metamorphic rocks?
Slide 21 - Open vraag
The rock cycle involves the transformation of igneous rocks into sedimentary rocks through processes like erosion and deposition.
Agree: It's part of the natural process.
Disagree: Their transformation is unrelated.
Agree: It's a key aspect of the cycle.
Disagree: Their transformation is inconsequential.
