Understand the Problem

The question is providing information about the occurrence and formation of minerals in different types of rocks, focusing on their definitions and geological processes. It references specific terms like 'veins,' 'lodes,' 'beds,' and mentions processes such as deposition, accumulation, and evaporation.

Answer

Minerals in igneous/metamorphic rocks form as veins/lodes; sedimentary minerals form in layers through deposition.

Minerals in igneous and metamorphic rocks form in cracks as veins or lodes from molten materials. Sedimentary minerals form in layers or beds through deposition and evaporation.

Answer for screen readers

Minerals in igneous and metamorphic rocks form in cracks as veins or lodes from molten materials. Sedimentary minerals form in layers or beds through deposition and evaporation.

More Information

Igneous and metamorphic minerals commonly consist of metals like tin, copper, and lead due to their formation from molten material. Sedimentary minerals include gypsum and salts, often formed through evaporation processes.

Tips

A common mistake is confusing the processes of mineral formation in igneous and sedimentary rocks. Remember that igneous rocks involve cooling magma, while sedimentary rocks involve deposition.
