Why is a quick burial helpful In the fossilization process?
GeologyThe rapid burial of remains beneath a blanket of sediment is critical to the process of fossilization because burial separates the remains from the biological and physical processes that would otherwise destroy them. Why is rapid burial important in the fossilization process because? Rapid burial is important in the fossilization process because: It protect a

What is the difference between Aphanitic and Phaneritic textures?
GeologyAPHANITIC TEXTURE – Igneous rocks that form on the earth’s surface have very fine-grained texture because the crystals are too small to see without magnification. PHANERITIC TEXTURE – Igneous rocks with large, visible crystals because the rock formed slowly in an underground magma chamber. What makes a phaneritic rock different from aphanitic rock? Phaneritic rocks
What are scour marks?
GeologyScour marks are negative relief features produced as a result of erosion of a sediment surface by the current flowing over it (Reineck and Singh 1980), formed via the impingement of usually sediment-laden eddies on beds (Dzulynsky and Saunders 1962). What do scour marks look like? Scour marks and flute casts Flute casts can be
Which volcano was formed by the subduction of the Cocos plate under the Caribbean plate?

What is a depositional environment in geology?
GeologyA depositional environment is defined as a site where sediments (e.g. detrital, chemical) accumulated, governed by physical, biological, and chemical processes related to modern and applied to ancient environments, and lithified into sedimentary rock units. What is an example of a depositional environment? Deep water marine environment – Flat area on the deep ocean floor
