The names of the three major groups of rocks refer to:

• Their mineral content

• Their chemical composition

• How they are formed

• Their age

Explain why granite is not considered a sedimentary rock, using evidence from its formation process.

• Granite forms from the cooling of magma, which is an igneous process.

• Granite is formed from the accumulation of sediments.

• Granite is formed under high pressure and temperature.

• Granite is formed from the evaporation of water.

Discuss the role of heat and pressure in the transformation of shale into slate.

• Heat and pressure cause shale to melt and reform as slate.

• Heat and pressure compact the grains in shale, aligning them to form slate.

• Heat and pressure dissolve shale, leaving behind slate.

• Heat and pressure cause shale to evaporate, forming slate.
