Ripple marks likely indicate that the rock formed……..
Near or in water

TRUE or FALSE?TRUE or FALSE?Metamorphic rocks that have a banded appearance due to the alignment of minerals are called foliated rocks.

Which rock is made up of the smallest sediments?
ShaleBreccia
SandstoneConglomerate

A fine grained igneous rock forms…..
Deep within the EarthFrom magma
As the result of slow coolingAs the result of quick cooling

The formation of igneous rock is powered by?
Earth’s Internal Heat
![Page 10: Chapter 3 Review: Rocks](https://reader035.fdocuments.in/reader035/viewer/2022081418/5681672b550346895ddbc910/html5/thumbnails/10.jpg)
If a rock has a porhyrtic texture, what can we conclude about the rock?
The rock went through at least two different cooling periods.
Minerals that crystallize from magma do not form at the same rate or same time. These rocks usually
have larger crystals surrounded by much smaller crystals.

How could you easily distinguish a black and white gneiss from a similar colored granite?
The gneiss is foliatedFoliated = bands or layers
