Patterns in the positioning of rock inside the Earth's crust are known as geologic structures. Parallel layering, which can be found in some volcanic deposits and sedimentary strata, is one of the most frequent patterns.
The strong tectonic forces that occur within the earth are typically what cause geologic structures. These forces result in deep faults, rock folding and breaking, and mountain formation.
What principal geologic features exist?
A few geological features developed simultaneously with the rocks in which they are found. These are fundamental buildings. Beds and laminae in sedimentary rocks like sandstone or shale and lava pillows in extrusive igneous rocks like basalt are examples of primary structures.
