4. How can subsidence lead to the formation of sedimentary rock?

5. Why are rift zones common places for igneous rock to form?

6. What would happen to the rock cycle if erosion did not occur?

7. Why is this statement not correct: An igneous rock must always become sedimentary rock next according to the rock cycle.

8. Why would granite have larger crystals that igneous rocks formed from lava cooled above Earth's surface?

When the ground subsides it can become lower than the surrounding terrain, forming a basin.

Since water, which carries sediment, flows downhill, sediment will collects in these basins.

If enough sediment collects, compaction and cementation will turn it into sedimentary rock.
