Minerals make up most of the rocks on earth's surface. what are three changes that can cause minerals to form by metamorphism?

temperature, pressure, chemical makeup

pressure, temperature, melting

pressure, physical makeup, melting

temperature, melting, physical makeup

Hello again,

i hope you having a great morning and thank you for asking how my morning too.

Feldspar is the most important mineral that makes up gneiss along with mica and quartz. Gneiss can be formed from a sedimentary rock such as sandstone or shale, or it can be formed from the metamorphism of the igneouse rock granite.

>magma "contacts" solid rock - heat is transferred into overlying rocks through conduction - changing the pre-existing rock it intruded.

> high heat/low pressure

> localized metamorphism

>"fast-acting," like touching a hot frying pan

*Country rock (surrounding) is baked from conduction

i hope this answer your question if not im so sorry

have great day

well, you see. the answer to your question is quite simple. the thing that is big, powerful, and over 9,000 is your mom.
