They form when layers of minerals lay on top of each other
Parallel alignment of minerals in metamorphic rocks typically forms under high temperature and pressure conditions. This alignment occurs when minerals recrystallize and orient themselves in a preferred direction due to the stress applied during metamorphism. This process is known as foliation and results in the development of distinct parallel layers or bands of minerals within the rock.
Metamorphic rock has undergone changes in temperature, pressure, or chemical composition, causing it to recrystallize and form new minerals.
Aventurine is a metamorphic rock. It is a form of quartz that contains small inclusions of other minerals, giving it a distinct shimmering appearance.
Metamorphic crystal growth refers to the process by which new crystals form in response to changes in temperature, pressure, or chemical environment within a rock undergoing metamorphism. This process can result in the development of different crystal types and structures compared to the original minerals present in the rock.
Some common metamorphic minerals found in rock formations include quartz, mica, garnet, and amphibole. These minerals form as a result of high pressure and temperature changes within the Earth's crust.

Minerals form in igneous rock as magma or lava cools. The minerals will form from the available chemicals in the magma as their crystallization temperature is reached. The sequence of mineral crystal formation from magma is described in the Bowen's Reaction Series. Metamorphic rock minerals are aligned, altered, or recrystallized from existing rock minerals due to the effects of heat and/or pressure.
If it is squeezed and heated sufficiently to realign the minerals or form new minerals, it is called a metamorphic rock. If it is squeezed and heated enough to melt, then solidify, it would be called an igneous rock.
Sometimes, but not always!

When the rock was forming other minerals that were near the forming place of the metamorphic rock were mixed in after the pressure has been made on the metamorphic rock. I am a seventh grade teacher so I know the answer. We are going over this in class right now.
No.
Heat and pressure causes Metamorphic Rocks to form.
Metamorphic rocks are made from the action of heat, stress, and pressure on pre-existing rocks, of either an igneous, or a sedimentary origin. Also, sometimes a metamorphic rock can be resculpted to form another metamorphic rock.
