Serpentine soil is made up of worn ultramafic rocks. These rocks are brought to the earth's surface by either tectonic uplift or erosion of material above the ophiolite. Because of the mineralogy and forces at work in the physical and chemical environment that constitutes metamorphism, the rocks are further classified...

The Appalachian Mountains The Appalachian Mountains are located in eastern North America. They stretch from Newfoundland to Alabama and are made up of valleys, ridges, and mountains (Dykeman, 2017).

The East African Rift formed 22-25 million years ago. The Rift was formed as a result of plate tectonics, with the Somalian and Nubian plates moving away from the Arabian Plate. Because of these forces, significant sections of the crust sank between the two parallel fault lines, forcing molten rocks...

Plate Tectonics: The Modern Update to Continental Drift Plate tectonics is the modern update to the idea of continental drift, which had been proposed by Alfred Wegener in 1912. This theory, first developed in the 1950s and 1970s, explains how the continents move around Earth's surface and how it can be...
