The correct answers are: grains form in parallel layers
and tend to split apart along bands.
Foliated rock is a type of metamorphic rock with characteristic striped pattern, meaning that its layers are distinct and repetitive. Such layers are formed under the influence of changed pressure (or heat): one layer is formed under the certain pressure, and the next at totally different pressure.
Organisms decompose more quickly when they are in contact with oxygen. ... When an organism is buried quickly, there is less decay and the better the chance for it to be preserved. The hard parts of organisms, such as bones, shells, and teeth have a better chance of becoming fossils than do softer parts.
