Fundamentals of Geomagnetism is the study of the Earth’s magnetic field and its interactions with the Earth’s atmosphere, oceans, and solid Earth. The Earth’s magnetic field is generated by the motion of molten iron in the outer core, which creates electric currents that produce the magnetic field.

The Earth’s crust is the outermost layer of the Earth and is the most familiar part of the planet’s surface. It is composed of a variety of rocks, minerals, and other materials, and is subject to a wide range of geological processes that have shaped its evolution over billions of years. Understanding the origin and evolution of the Earth’s crust is a fundamental area of research in geology, as it provides insight into the formation and development of the planet as a whole.

Endogenetic and Exogenetic Forces: The processes that bring about changes on the earth’s surface are known as geomorphic processes. These processes are divided into two: Endogenetic and Exogenetic processes. The forces which derive their strength from the earth’s exterior or originate within the earth’s atmosphere are called exogenic forces or external forces. While the endogenic forces, also called internal forces, are used to describe pressure that originates inside the earth.
