Does chemical process change he form of existing rock?
yes
The leaching of rock by acid precipitation is a form of?
Chemical Weathering
How does a chemical sedimentary rock form?
When minerals crystallize from a solution
Why does lava turn in to a rock?
Lava is made of the same chemical components that are found in many rock types (mostly silica and various metal oxides), only it is in a superheated, molten form. When the lava cools, the chemical components form the appropriate rock.
What are the differences between chemical rocks and sedimentary rocks?
The term chemical rock is redundant, since all rocks, and all substances, are made of chemicals. Every rock is a chemical rock. Sedimentary rock is rock that is composed of solidified sediment, such as sandstone. Little pieces become cemented together to form rock.
What type of sedimentary rock would form in an evaporating desert lake?
Chemical (or non-clastic) sedimentary rock.
What type of rock is Limestone made from Shells?
carbonaceous shells form limestone which in this case is a bio-chemical sedimentary rock
What occurs as the results of a rocks exposure to a chemical?
The answer will depend on what the chemical is! A rock exposed to nitrogen, under normal temperature and pressure will be no different from what it would be otherwise!
What are the main sub-categories Sedimentary Rock?
The main sub-categories of sedimentary rocks are clastic, chemical, and organic. Clastic sedimentary rocks form from the accumulation and cementation of fragments of pre-existing rocks. Chemical sedimentary rocks form from the precipitation of minerals from water solutions. Organic sedimentary rocks form from the accumulation and compression of organic materials, such as plant or animal remains.
What does not change the form of existing rock?
When there is no weathering. When there there are no intrusions of magma beneath rock no metamorphic rock will form. But, this is impossible as the Earth atmosphere and interior forces are so dynamic. Over time all rocks will undergo some kind of change.
Where do chemical rocks form?
Chemical sedimentary rock is created by precipitation of minerals out of, or evaporation from, saturated solutions that are high in dissolved minerals. Rock gypsum and rock salt are two examples.
Where do rocks come form?
Nearly all rocks had their beginning as magma - molten rock. This forms igneous rock that weathers to form sedimentary rocks. Sedimentary rock may be changed by heat and pressure to form metamorphic rock. The exception is limestone which is formed by chemical precipitation or from fossils.
