What weathering alter the internal structure of minerals by removing and or adding elements?

Chemical weathering


Are minerals natural?

Yes. Minerals are naturally occurring inorganic elements or compounds with a definite internal structure of ions and a chemical formular.


Why are quartz grains and clay particles the most common lithogenous sediments conveyed to the ocean?

Lithogenous sediment particles are produced by wind and water erosion and weathering of terrestrial rocks. During weathering, easily dissolved minerals are removed, leaving mostly siliceous minerals including quartz, feldspars, and clay minerals. Clay minerals are layered structures of silicon, aluminum, and oxygen atoms, some containing iron and other elements. They are then carried to the oceans by rivers, glaciers, and winds, or eroded from coastlines by waves.


How does weathering change minerals?

Physical or mechanical weathering


What are the primary elements that connect the large silicate structures to one another in the silicate minerals?

What is the silicate mineral that originates as a product of chemical weathering?

Clay minerals are the product of chemical weathering of silicate minerals, such as feldspars. Clays are silicate minerals.


What do both weathering and erosion produce?

New rocks, landforms and structures. The first from the sediments from the weathered rocks. Also solutions of minerals such as calcium carbonate, from limestone.


A type of chemical weathering in which minerals react with dissolved oxygen in water is known as?

Physical weathering is a type of weathering in which minerals react with dissolved oxygen in water. This causes chemical changes to take place in the minerals.


What happens to the minerals in rocks as a result of chemical weathering?

During chemical weathering, minerals in rocks can undergo a process of decomposition and transformation. This occurs as water and atmospheric gases react with the minerals, causing them to dissolve or alter their chemical composition. For example, minerals rich in iron can oxidize and form rust, while silicate minerals can break down and release their constituent elements. Ultimately, this can lead to the formation of new minerals and the release of dissolved ions into water streams.


What is it called when chemical reactions dissolve the minerals in rock or change them into different minerals?

It's called dissolution, a form of chemical weathering.


What type of structures are minerals?

Maybe minerals is a type of structures of phosphates or carbonates


Do lichens use chemical weathering?

Yes. Chemical weathering is performed by the fungal portion of a lichen symbiote (fungus and autotrophic plant) to anchor itself to rock and sometimes to extract minerals. The rootlike structures called rhizines excrete dilute acids.
