What else can I help you with?
What If two minerals have the same chemical composition but cleave into different shapes what is true?
They have different structures.
How does epidote form?
Epidote is formed from a set of minerals, and it is used to form other mineral types of its own kind by chemical reactions on it.
Why is a boulder not a mineral?
A mineral is a naturally occuring chemical compound. A mineral is different from a rock/boulder which can be an aggregate of minerals, or non minerals and does not have a specific chemical composition as a mineral does
Why is the desert soil rich in minerals?
The desert receives little rainfall that would normally dissolve and wash away minerals.
Chemical composition of non living things?
Basic Geology lists over 200 different types of non living minerals.
What type of weathering occurs when reactions dissolve the minerals in rock?
Chemical weathering occurs when reactions dissolve the minerals in rocks. This process occurs when minerals in the rock react with water, air, or other substances to break down the rock. One common example of this is the weathering of limestone through the dissolution of calcite by carbonic acid in rainwater.
What is the importance of water to chemical weathering?
Water plays a crucial role in chemical weathering by acting as a solvent that helps to break down rocks and minerals. Water can dissolve minerals, carry away weathering products, and facilitate chemical reactions that further break down rocks. Without water, chemical weathering processes would be significantly slower or nonexistent.
What role of gases such as oxygen and carbon dioxide in chemical weathering?
Oxygen causes oxidation reactions; carbon dioxide with water (as carbonic acid) dissolve minerals.
Which forms when minerals dissolve in a water solution crystallize?
Chemical Rock
What is the process by which rocks break down as a result of chemical reactions called?
The process by which rocks break down as a result of chemical reactions is called chemical weathering. This occurs due to the effects of water, air, and other substances on the minerals that make up the rock, causing them to decompose or dissolve over time.
What is the process that breaks down rocks by changing their composition?
Chemical weathering is the process that breaks down rocks by changing their composition through chemical reactions with substances like water, oxygen, and acids. This can alter the minerals within the rock and cause them to dissolve or transform into new minerals.
Chemical weathering changes quartz to clay minerals?
Chemical weathering of quartz involves the breakdown of its crystal structure, resulting in the formation of clay minerals. This process typically involves reactions with water and acids that dissolve minerals in the rock, leading to the formation of clay minerals like kaolinite, illite, or montmorillonite. Clay minerals are fine-grained and layered silicate minerals that are often the end product of chemical weathering of quartz-rich rocks.
Do vitamins work with minerals to initiate chemical reactions within cells?
Yes, vitamins can work with minerals as co-factors to help initiate chemical reactions within cells. For example, vitamin C can enhance the absorption of iron, a mineral that is essential for the production of red blood cells. Together, vitamins and minerals play important roles in supporting various cellular processes in the body.
What does oxygen and carbon dioxide do in chemical weathering?
In chemical weathering, oxygen can react with minerals to create oxides, which can lead to the breakdown of rocks. Carbon dioxide can dissolve in water to form carbonic acid, which can further break down minerals in rocks through chemical reactions. Together, oxygen and carbon dioxide play a role in accelerating the process of chemical weathering.
Why is water the major agent of chemical weathering?
Water is the major agent of chemical weathering because it can dissolve minerals in rocks, facilitating chemical reactions that break down the rocks over time. Water also provides a medium for reactions to occur and helps transport dissolved minerals away from the weathering site. The abundance and properties of water make it highly effective in altering and breaking down rocks chemically.
How does a minerals from?
Combinations of elements formed by chemical reactions, heat, and/or pressure.
The most important agent of chemical weathering is .?
water
