The key difference between Davis and Penck cycle of erosion is that Davis cycle of erosion is a geographic cycle model that is monocyclic and time-dependent, while Penck cycle of erosion is a geographic cycle model that is polycyclic and is not time-dependent. The cycle of erosion depicts the development of relief in landscapes. The […]

The key difference between pyrite and marcasite is that pyrite has an isometric crystal system, whereas marcasite has an orthorhombic crystal system. Pyrite and marcasite are two forms of iron sulfide minerals containing iron in a +2 oxidation state. Although the two mineral forms have the same chemical composition, they have different crystal systems. CONTENTS […]

The key difference between chemical and detrital sedimentary rocks is that the formation of chemical sedimentary rocks does not involve direct  mechanical weathering, whereas the formation of detrital sedimentary rocks involves direct mechanical weathering. Sedimentary rock is formed from pre-existing rocks or pieces of once-living organisms. These rocks form through the depositions that get accumulated on […]

The key difference between epicenter and hypocenter is that epicenter is the point that exists directly above the hypocenter whereas hypocenter is the point at which an earthquake or an underground explosion originates. Epicenter and hypocenter are two important terms in the field of seismology, especially in describing earthquakes and underground explosions. CONTENTS 1. Overview […]

The key difference between gypsum and phosphogypsum is that gypsum is a naturally occurring form of calcium sulfate, whereas phosphogypsum is a synthetic form of calcium sulfate. More specifically, gypsum is a rock-forming, soft crystal obtained by mining or quarrying, but phosphogypsum is a by-product during the production of superphosphate from phosphate rock. Therefore, both […]
