Collision and Compressional forces.
what causes a rock to break into many layers. DOES WATER
The force that causes rock layers to crumple and fold is mainly tectonic forces, such as compression. When two tectonic plates collide or move toward each other, the rocks in between experience intense pressure, leading to deformation and folding of the rock layers.
== == An upward fold in a rock formation is called an anticline.
A downward fold in a rock is called a syncline. It is a type of fold in which the rock layers are bent downward in a trough-like shape.
Such a fold is called a syncline.
If rocks are folded, the folding is younger that the youngest rock affected. If they are folded into a syncline (a U-shaped fold) the youngest rocks are in the core of he fold. The opposite is true for an anticline (a big dome-shaped fold).
calcium causes that
A geological fold occurs when a flat surface like sedimentary rock are deformed and bent. It can occur through natural stress, water pressure or man made causes and engineering.
Fold
A syncline fold is concave downward, meaning the youngest rock layers are found in the center of the fold and the oldest rock layers are found on the outer edges of the fold.
The compass direction of a fold or a rock layer exposed at the surface along a fold is referred to as the trend of the fold. This trend helps geologists determine the orientation and direction of the folding of rock layers in the Earth's crust.
