What type of rocks are banded or non banded?
Slate is a type of metamorphic rock. It is a foliated metamorphic rock that has a banded, or layered, appearance due to exposure to directed pressure and heat.
What term describes an erosional surface bounded above by flat-lying sedimentary rocks and below by igneous or metamorphic rocks?
nonconformity
Where in the Bronx can one find igneous sedimentary and metamorphic rocks?
If you can find an open piece of dirt, you can find rocks. All rocks fallinto those three categories. If you find a flat, smooth piece of rock, you might have found slate, a metamorphic rock. However, most metamorphic rocks are hard to find in the New York area, as there are few plate tectonics in these parts. Anyhow, look for rocks and use this rock key: http://www.rockhounds.com/rockshop/rockkey/index.html
What does it mean if the rock layers are foliated?
The foliation is caused by the massive force of pressure and high temperature which results from mountain building processes caused by plate collisions. The heat and pressure combine to realign the existing minerals from a random orientation to one of parallel orientation, thus creating the visible lines or platy cleavages found in foliated metamorphic rocks. The lines of foliation are created perpendicularly to the force being applied.
If you found a rock with flat mineral grains which rock would it be?
Metamorphic Rock
Flat or wavy parallel bands of minerals within rocks?
foliation
What describes the thin flat layering in most metamorphic rocks?
The thin flat layering found in most metamorphic rocks is called foliation
What term is used to describe metamorphic rocks with a banded texture?
The two main groups of metamorphic rocks are foliated and non-foliated. Foliated metamorphic rocks show layering and parallel alignment of flat mineral crystals (ex. micas). The "banded texture in metamorphic rocks" is one of the specific kinds of foliated textures. It is referred to as gneissic banding. Essentially, this texture displays alternating layers of light and dark minerals. These rocks are called gneiss- the light bands form from quartz and feldspars, while the dark ones form from ferromagnesian minerals.

What is the arrangement of minerals in a parallel or wavy or flat bands?
foliation
What is an arrangement of minerals in flat or wavy parallel bands?
Foliation.. of course!

What term describes an erosional surface bounded above by flat-lying sedimentary rocks and below by igneous or metamorphic rocks?
nonconformity
What condition produces the distinct layers of flat and elongated minerals in the foliated metamorphic rocks?
High Pressure.
What is a nonfoliated texture?
A non-foliated rock is a metamorphic rock that does not display a lamellar texture or distinct light and dark banding common to foliated metamorphic rocks. Non-foliated rock includes quartzite, marble, and metabasalt. Non-foliated metamorphic rocks are most often derived from single mineral sedimentary rocks like limestone and quartz sandstone. == == == ==
