GENERAL GEOLOGY

Detailed explanation-1: -stratification, the layering that occurs in most sedimentary rocks and in those igneous rocks formed at the Earth’s surface, as from lava flows and volcanic fragmental deposits.

Detailed explanation-2: -When volcanoes erupt, the lava that comes out can spread across broad areas, forming a layer of igneous rock within the sedimentary layers. Thus, most of the layering on the Earth’s surface is due to erosion and deposition of mountain ranges, and lava flowing out on the surface.

Detailed explanation-3: -The whole process of land formation is called EROSION. Erosion is the wearing away of the Earth’s surface by the act of natural forces.

Detailed explanation-4: -Stratification The most important feature of sedimentary rock is stratification. Stratification is the process in which sedimentary rocks are arranged in layers.

Detailed explanation-5: -Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water.
