is typically formed by metamorphism of a sandstone. is typically formed by metamorphism of a sandstone. Quartzite Slate Amphibolite Marble

Quartzite is formed from the metamorphism of sand stone

Quartzite

Explanation:

The changes or the transformation of an existing rock because of chemical changes, pressure and temperature is known as metamorphism. During the process of metamorphismm the existing rock change its texture geologically but they do not turn into a liquid magma.

When sandstone is subjected to heat, pressure and any other natural agencies Quartzite is being formed. Quartzite is a metamorphic rock and it derived it hardness mainly from its richness in quartz.

i am going to guess that it is co2.

endo:

regulates body hormones, aldosterone, vasopressin

neural:

signal, regulates body using electric signals, reflex

endo has to do with hormones; aldosterone and vasopressin are both hormones. i also had this question and got it right : d
