Paleomagnetism is the study of the Earth’s past magnetic fields present in rocks and fine sediments like an actual record that can be enjoyed when played on the reverse.
Volcanology is the study of volcanoes. It helps in delineating the processes taking place in the interior of the earth that results in the eruption of hot molten magma on the surface of the planet earth.
“Isostasy is the state of gravitational equilibrium between Earth’s crust and mantle such that the lighter crust “floats” at an elevation that depends on the thickness and density of the underlying layer.”
Geodes in stratified volcanic rocks form in particular geochemical environments where hollow bubbles form inside the layers of rocks.
Have you ever imagined, our Earth becoming a global village having no more different continents but just one? Alternatively, will you believe if I say that Antarctica was once a warm landmass with dense tropical rainforests growing on it? If the answer is no, then probably you should explore this fascinating theory of Continental drift because appearances can be deceptive in the field of geology.
