WebWhat factors control metamorphism? Metamorphic rocks may be formed from sedimentary rocks, igneous rocks or existing metamorphic rocks. Loose sediments such as mud, silt or sand first become changed to a sedimentary rock by compaction and by cementation of the grains by a natural “cement”. This cement is mostly composed of … WebFactors that Control Metamorphism Metamorphism occurs because rocks undergo changes in temperature and pressure and may be subjected to differential stress and … WebThe most important factors controlling the characters of metamorphic rocks include ___. a) composition of the parent rock b) temperature c) pressure d) water e) All of the choices are correct. ...

WebTectonic Forces. Rocks are under stress when they are subjected to a force at depth. When the rocks are exposed at the surface after uplift and erosion, the effects of the stress can be studied. Stressed rocks show varying degrees of strain —the change in the volume and/or shape of the rock because of that stress. WebJan 3, 2024 · Factor controlling metamorphism. 37 related questions found.

Intrusions are also classified according to size, shape, depth of formation, and geometrical relationship to the country rock. Intrusions that formed at depths of less than 2 kilometers are considered to be shallow intrusions, which tend to be smaller and finer grained than deeper intrusions. Dikes.

WebWeathering. The process of weathering alters rocks at the earth's surface and breaks them down over time into fine‐grained particles of sediment and soil. Weathering is the result of the interactions of air, water, and temperature on exposed rock surfaces and prepares the rock for erosion. Erosion is the movement of the particles by ice, wind ...

WebIsostatic Equilibrium. Huge plates of crustal and upper mantle material (lithosphere) “float” on more dense, plastically flowing rocks of the asthenosphere. The “depth” to which a plate, or block of crust, sinks is a function of its weight and varies as the weight changes. This equilibrium, or balance, between blocks of crust and the ... WebStream Valleys. The erosion and transport of rock and sediment by a stream defines the shape and extent of its valley. V‐shaped valleys and wide valleys with flat floors are the most common varieties. Downcutting. A valley is the result of downcutting, whereby a stream's channel erodes directly downward. As downcutting continues, erosion and ...
