Science 5 Chapter 1 Review

How would the flood contribute to the formation of sedimentary rock?

• the flood waters stirred up a lot of dirt and particles that settled into layers as the waters receded

• the volcanic activity would cause rocks to cool and form sedimentary rock

• the great tectonic plate movement caused immense temperatures and pressures to form sedimentary rock deep in the crust

How could weathering and erosion help people find minerals?

• it can remove the surface layers to reveal buried minerals

• it can form new minerals on the surface

• weathering and erosion can only destroy minerals and is never a good thing for a geologist
