How can you tell a rock is a metamorphic rock?

Answer 1

Collect some big rocks from backyards, parks, sidewalks anywhere were you can find rocks. Have a hammer and gently pound on the rock several times until it cracks open. If crystals or gems fall out, be proud and keep them. If they don't, no crystals.

NOTE: Don't use the rocks that you can buy from HomeDepo for decoration because they DO NOT work!! No gems or crystals will fall out!!!

Answer 2

As we all know these rocks are formed at areas of high temperature and pressure. These rocks are ruch in minerals like sillimanite, kyanite, staurolite, andalusite, and some garnet.Other minerals, such as olivines, pyroxenes, amphiboles, micas, feldspars, and quartz. If we see any folded foliation or interlayering formation on the surface of the rock it is definitely a metamorphic rock

Answer 3

Metamorphic rocks have undergone changes in temperature and pressure, causing them to recrystallize. Look for distinct mineral layers, banding, or foliation in the rock, which are common features of metamorphic rocks. Additionally, metamorphic rocks often have a shiny or glassy appearance due to the rearrangement of minerals during metamorphism.

Answer 4

Rocks that are in fact meteorites have a fusion crust on the outside. A fusion crust tiny cracks on the surface of the rock that formed as the meteorite crossed into the atmosphere.

Answer 5

get a big rock and hit it lightly a few times with a hammer until it breakes open and you will or wont find crystals.

Answer 6

light and dark color bands i think
