William Gilbert, an English scientist, proposed that the Earth itself acts like a giant magnet with magnetic poles similar to those found in compass needles. He coined the term "magnetic poles" and laid the groundwork for understanding Earth's magnetic field. Gilbert's work helped pave the way for modern studies of geomagnetism.
The idea that continents move slowly across Earth's surface is called plate tectonics. This theory explains how the Earth's lithosphere is divided into plates that move and interact with each other, leading to processes such as earthquakes, volcanic activity, and the formation of mountain ranges.
Studying Earth's history through fossils and sedimentation is not an idea geologists use. Geologists primarily focus on studying the Earth's structure, composition, and processes like plate tectonics and rock formation to understand its evolution and dynamics.
The physical mass of Earth isn't changing. The amount of habitable land is shrinking due to rising seas & advancing deserts.
Earth's surface was originally thought to be flat, based on early observations and beliefs. This notion persisted until evidence from explorations and scientific understanding supported the idea of a spherical Earth.
Wegener's idea is known as continental drift. He proposed that the Earth's continents were once connected as a single landmass called Pangea and have since drifted apart over time.

William Gilbert's great discovery was his work on magnetism, where he demonstrated that the Earth itself behaves like a giant magnet with north and south poles. This discovery laid the foundation for our current understanding of geomagnetism and the Earth's magnetic field.
