What two chemical constituents cannot form by chemical weathering of the feldspar minerals?
Quartz and clay minerals cannot form by chemical weathering of feldspar minerals. Quartz is already a stable mineral and does not transform during weathering, while clay minerals originate from the breakdown of feldspar.
Is ice wedging chemical weathering?
No, it is physical weathering. Ice wedging occurs when water seeps into cracks in rocks and freezes. Water expands when it freezes, and when that happens it can crack the rock, causing the rock to break down over time. No chemical changes occur during this process. The water stays water, it just changes state, and the rock stays rock, it just breaks down into smaller pieces.
Which property of matter changes during a chemical change but does not changes during a physical change?
The composition of matter changes during a chemical change as new substances are formed with different chemical properties. In contrast, the composition of matter remains the same during a physical change, with only the physical state or appearance of the substance being altered.
Are the effects of acid from decaying animals a form of chemical weathering?
Lichens and mosses grow on essentially bare rock surfaces and create a more humid chemical microenvironment. The attachment of these organisms to the rock surface enhances physical as well as chemical breakdown of the surface microlayer of the rock. On a larger scale, seedlings sprouting in a crevice and plant roots exert physical pressure as well as providing a pathway for water and chemical infiltration. So, i think it is a form of chemical weathering. Or at least that was the closest answer i could find
What is the study of heat transfer during chemical reactions and changes of state is?
The study of heat transfer during chemical reactions and changes of state is known as thermochemistry. Thermochemistry deals with the heat of reaction, enthalpy, and heat transfer in chemical processes. It is important in understanding the energy changes associated with chemical reactions.
What can occur during a chemical reactions?
Weathering can be mechanical or chemical.
Why does June and July have the highest rate of chemical weathering?
It has the highest rate of chemical weathering because chemical weathering occurs much faster in hot, humid climates. This makes rain forests a target for chemical weathering, and in hot seasons, the weathering skyrockets.
Are fossils chemical or mechanical weathering?
Fossils are nothing to do with weathering they are formed during the deposition of sediments before they become rocks.
Why does June and July had the highest rates of chemical weathering?
June and July typically have the highest rates of chemical weathering because they are warmer months with increased temperatures, which accelerate chemical reactions. In addition, the increased rainfall during these months provides more moisture, which promotes chemical weathering processes.
What two chemical constituents cannot form by chemical weathering of the feldspar minerals?
Quartz and clay minerals cannot form by chemical weathering of feldspar minerals. Quartz is already a stable mineral and does not transform during weathering, while clay minerals originate from the breakdown of feldspar.
Atoms of different elements unite during chemical changes to produce what?
Atoms of different elements unite during chemical changes to produce at least one chemical compound.
Rocks are broken down into sediment during what?
Rocks are broken down into sediment during the process of weathering, which involves various physical, chemical, and biological processes breaking down and disintegrating rocks into smaller particles. This can happen due to factors like temperature changes, water, wind, and biological activity.
What occurs during weathering?
Weathering is the process by which rocks and minerals are broken down into smaller pieces through various physical, chemical, or biological means. Physical weathering involves the mechanical breakdown of rocks, while chemical weathering involves the alteration of rock composition through chemical reactions. Biological weathering is the breakdown of rocks by living organisms, such as plant roots or burrowing animals. Over time, these processes can contribute to the formation of soil and shape the Earth's surface.
Is leaves decaying in the forest chemical or mechanical weathering?
The process of leaves decaying in the forest is considered to be chemical weathering. During decay, organic matter in the leaves breaks down and releases minerals into the soil, altering its composition. This chemical process aids in the weathering of rocks and contributes to soil formation.
Is ice wedging chemical weathering?
No, it is physical weathering. Ice wedging occurs when water seeps into cracks in rocks and freezes. Water expands when it freezes, and when that happens it can crack the rock, causing the rock to break down over time. No chemical changes occur during this process. The water stays water, it just changes state, and the rock stays rock, it just breaks down into smaller pieces.
Is chemical energy related to chemical change?
Yes it is released/ absorbed during chemical changes.
Why do you think those two months had the highest rates of chemical weathering?
The high rates of chemical weathering in those two months could be due to increased humidity levels, which can accelerate chemical reactions on rocks and minerals. Additionally, seasonal variations like temperature fluctuations and rainfall patterns may have also contributed to the heightened chemical weathering during that time.
