Rocks, Minerals, Weathering

How are rocks classified into 3 different groups?

• Rocks are classified according to how they form.

• Rocks are classified by their color.

• Rocks are classified by their size.

• Rocks are classified by their location.

Using the diagram below, name the 2 processes that must occur to change an igneous rock into a metamorphic rock.

• Heat and pressure.

• Melting and cooling.

• Weathering and erosion.

• Compaction and cementation.

What process causes the breakdown of rocks into smaller pieces or changes their shape?

• Weathering.

• Condensation.

• Photosynthesis.

• Evaporation.

How do the 3 types of rocks form?

• Sedimentary rocks form from compaction or cementation of small pieces of rock called sediment or from the evaporation of water.

• Igneous rocks form from the melting and solidifying of liquid rock (magma or lava).

• Sedimentary rocks form from the melting of minerals, and igneous rocks form from the compaction of sediment.

• Metamorphic rock forms from a lot of heat and pressure on any type of rock.

  
  

Energy plays a role in the formation of rocks by:

• Weathering to make rocks smaller.

• Heat energy from inside the Earth creates magma and the heat forms metamorphic rocks.

• making rocks lighter in weight

• Small rocks compact to make sedimentary rock.

Using the rock cycle diagram below, identify the two processes that create sediment and the four processes that change sediment into sedimentary rock.

• Weathering and erosion; compaction, cementation, deposition, burial

• Melting and cooling; compaction, cementation, deposition, burial

• Weathering and deposition; melting, cooling, compaction, cementation

• Erosion and deposition; melting, cooling, compaction, cementation
