Why would newer rock layers ever be below older rock layers?
Due to faulting or folding.
What is the force that causes rock layers to crumple and fold?
Compressive stress causes the "crumpling" and folding of rock layers.
How can older rocks be found above younger rocks in a cross section?
Older rocks can be found above younger rocks in a cross section due to processes like faulting and folding. Faulting occurs when rock layers break and move along a fault plane, causing older rocks to be displaced above younger rocks. Folding occurs when rock layers are subjected to compressive forces, resulting in older rocks being pushed up and over younger rocks. These geologic forces create the observed order of rock layers in a cross section.
When rock layers bend due to stress?
"Folding" is the term that describes the bending of rock layers due to stress.There are different types of Folds and these include:Anticlinal Folds: This is when the rock layers have an upward-arching folds.Synclinal Folds: This is when the rock layers have a downward, trough-like folds.Monoclinal Folds: This is when both rock layers ends are horizontal.
What forms when the rock layers slip or slide along the crack?
Faulting.

Explain that folding faulting and uplifting can rearrange the rock layers so the youngest is not always found on top?
Whenfolding, faulting, and uplifting occurs, the youngest rock layer can not always be on top. With folding the oldest rock layer could get folded over on top of a younger layer. When faulting occurs a younger rock layer can become "lower" or pushed more down in the rock layers that was originally shown. When these things happen, then rock layers can become out of order and the youngest layer is not always on the top of the layer.
What causes a gap in the geologic record?
Erosion of already deposited layers or a time span of non-deposition.
How does folding and faulting change the law of superposition?
tilting, folding, and faulting may also complicate the analysis of a stratigraphic sequence. Additionally, molten rock may force its way through surrounding rocks and might squeeze between older rock layers, also forming an exception to the laws. However, such anomalies leave physical evidence for geologist to find in the disturbed rocks - for example, faulted rock layers may be cracked, broken, or metamorphosed along the fault lines.

How does folding change rock layers?
Most rock layers (and ALL sedimentary layers) start out flat. Folding changes the angle of lie (even to perpendicular and beyond).
What does folding do to layers of rock?
what causes a rock to break into many layers. DOES WATER
In geography terms what does folding mean?
Folding is the bending of rock layers due to stress.
Diffrenciate geologic time with geologic column?
Geologic column is an ordered arrangement of rock layers that is based on the relative age of the rocks. Geologic time is the time IN the geologic column.
