Muscovite mica has perfect cleavage in one direction. It splits into thin sheets.
Mica Is Not A Renewable Resource Because Think About When Muscovite Mica And Biotite Mica Go Extinct. Muscovite Mica And Biotite Mica Are Both Types To Make Mica, And If That Goes Extinct Then Mica Will Be Extinct Too.
