Formation of Chalk and Sovite


Formation of Sovite and Chalk


Formation

Formation
Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.  
Sovites are formed due to low degrees of partial melting of rocks.

Chalk and Sovite Formation

Formation of rocks is a long process and hence, Chalk and Sovite formation sounds very interesting. According to the formation, all rocks are divided into :Igneous Rocks, Sedimentary Rocks and Metamorphic Rocks. Igneous rocks form by crystallization of magma or lava. The magma is made up of various components of pre-existing rocks which have been subjected to melting either at subduction zones or within the Earth's mantle. Igneous rocks are generally seen at mid ocean ridges or in intra-plate hotspots. Sedimentary rocks are formed when sediments accumulate gradually. As the sediments are buried they get compacted as more and more material is deposited on top. Eventually the sediments become so dense that they form a rock. Metamorphic rocks are rocks which once existed as igneous or sedimentary rocks but have been subjected to varying degrees of pressure and heat within the Earth's crust. Get to know all about formation of Chalk and Sovite, composition of Chalk and Sovite and their transformation.
