What does fine grain mean?
Regional SpecificsDefinition of fine-grain 1 : producing images of low graininess so that considerable enlargement without undue coarseness is permitted —used of a photographic developer. 2 or less commonly fine-grained \ ˈ⸗¦⸗ \ : characterized by comparatively fine graininess —used of a photographic image or photographic emulsion. What is fine grained and coarse-grained? The word ‘granular’
What does regional metamorphism result in?
Regional SpecificsLarge geological processes such as mountain-building cause regional metamorphism. When exposed to the surface, these rocks show the incredible pressure that causes the mountain building process to bend and break the rocks. Regional metamorphism usually produces gneiss and schist-like foliated rocks.May 22, 2019 What is formed by regional metamorphism? Regionally metamorphosed rocks usually have a
Can lava be removed?
Regional SpecificsContractors with experience removing lava flows said it can take months for the lava to harden and cool enough to remove safely.May 17, 2018 Can lava Be Stopped? Barriers designed to impede or redirect the flow of lava are a far more commonly deployed method. “They seem to more reliably buy time than bombing does,”
What is the process of compaction and cementation?
Regional Specifics1. Compaction occurs when the overlying sediments’ weight compacts the grains as tightly as possible. 2. Cementation is the process whereby dissolved minerals in the water between the grains crystallize cementing the grains together. What is the process of compaction? happens when sediments are deeply buried, placing them under pressure because of the weight of
Which layer is defined by its physical properties?
Regional SpecificsLithosphereLithosphere. The lithosphere is the outermost layer of the Earth ~100 km thick and is defined by its mechanical properties. This rigid layer includes the brittle upper portion of the mantle and the crust.Aug 21, 2019 What are the Earth’s layers based upon physical properties? Earth has five layers based on physical properties: the inner
What conditions in Earth can cause metamorphic rocks to form?
Regional SpecificsMetamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Conditions like these are found deep within the Earth or where tectonic plates meet. What conditions in Earth can cause metamorphic rocks to form except ____? all of the following conditions in
