The two major sources of chemically unreacted rocks are igneous rocks and metamorphic rocks. Igneous rocks form from the cooling and solidification of magma or lava, while metamorphic rocks are formed by the alteration of pre-existing rocks through heat and pressure without melting.
What else can I help you with?
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.
What are plant like organisms that grow on rocks and produce weak acids that chemicaly weathers rocks?
Lichens are plant-like organisms that grow on rocks and produce weak acids that chemically weather rocks. They are a symbiotic relationship between algae or cyanobacteria and fungi, and their ability to break down rocks contributes to soil formation over time.
What is the major reservoir of phosphorus cycle?
The major reservoir of the phosphorus cycle is in rocks and sediments. Phosphorus is released into the environment through weathering of rocks, where it can then be taken up by plants and other organisms.
What is the sources of phosphates?
Sources of phosphates include fertilizers, detergents, wastewater from households and industrial activities, and agricultural runoff. Phosphates can also be naturally occurring in rocks and minerals.
Minerals that are heavy durable and chemically resistant are likely to be found in?
placer deposits
Are sedimentary rocks chemically weathered?
Sedimentary rocks can be both chemically and mechanically weathered.
Some rocks react chemically with what in the environment?
Rainwater.
Does wind weather rocks mechanically or chemically?
Mechanically
What Are Chemically Formed Sedimentary Rocks Formed From?
Chemically formed sedimentary rocks are formed from dissolved minerals that precipitate out of water through processes like evaporation or chemical reactions. Examples include rocks like limestone, rock salt, and gypsum.
Why don't lunar rocks chemically weather?
No atmosphere-no weather.
Do natural acids mechanically or chemically weather rocks?
Natural acids chemically weather rocks by reacting with minerals in the rock, causing them to break down. Mechanical weathering involves physical processes like freezing and thawing, which cause rocks to break apart without altering their chemical composition.
What are three ways sedimentary rocks can form?
Biologically, Chemically and Mechanically.
What is weathering that breaks down rocks without changing it chemically?
erosion
What kind of texture can a chemically formed rock have?
All sorts as all rocks have their own textures and are all formed from chemical compounds, but the primarily chemically-formed ones are the igneous rocks and associated minerals.
What is the word for the kind of weathering that chemically changes rocks?
dere id non
What is the definition for chemically changed by sedimentary rocks?
I love one direction ♥
Can polluted air break down rocks?
Human pollution is generally acidic. Sometimes, the pollution can contaminate rainclouds or other sources of water, forming an acidic liquid. If a rock has contact with this substance, it could be eroded chemically.
