Which best describes the formation of metamorphic rock?
They are formed through the cooling and hardening of magma or
lava, both below Earth's surface or on Earth's surface as volcanic
rocks.
They are formed by deposited sediment, usually at the bottom of
lakes and oceans, that is compressed over time into solid layers of
rock
They are formed as extreme weather elements, like tornadoes and
floods, break down mountains and other rock landforms into smaller
pieces.
They can be formed from any of the three rock types, withstanding
high temperatures and pressures, and forming new minerals without
melting.

Idid a lab for chemistry where we put nails in a copper (ii) chloride solution. 1. why did the reaction stop? which reactant was used up? how do you know? 2. describe what was happening to the atoms of iron and copper during the reaction. what is this type of reaction called? 3. what would happen to the ratio of copper to iron if you had placed more nails in the beaker? if you had let the reaction go for less time? 4. what is the accepted ratio of copper atoms to iron atoms in this reaction? account for differences between your experimental value and the accepted value. write the balanced equation for the reaction.
