Explain how chemical and physical processes cause carbon to cycle through the major earth reservoirs?
Carbon exists in the Earth's atmosphere primarily as the gascarbon dioxide. Trees convert carbon dioxide into carbohydrates during photosynthesis, releasing oxygen in the process. The effect is strongest in deciduous forests during spring

Is twisting a wire chemical or physical change explain?
It is physical. The wire changes shape, but it is still made of the same materials.
Explain the similarities and difference between physical weathering and chemical weathering?
Physical weathering involves the breakdown of rocks into smaller fragments without altering their chemical composition, typically through processes like freezing and thawing or abrasion. Chemical weathering, on the other hand, involves the decomposition of rocks through chemical reactions that change their composition, such as oxidation or dissolution by acidic water. Both processes contribute to the overall breakdown of rocks, with physical weathering primarily affecting the size and shape of rocks, and chemical weathering changing their chemical structure.
Is it a chemical or physical change when heat is put over sugar?
its physical change.to explain,the conversion of solid to liquid is physical
Explain the difference between chemical and physical weathering?
Chemical weathering involves the breakdown of rocks through chemical reactions, such as oxidation or dissolution. Physical weathering, on the other hand, occurs when rocks are broken down into smaller pieces through physical processes like freezing and thawing, or abrasion. Chemical weathering changes the composition of the rock, while physical weathering only breaks the rock into smaller pieces.
When the banana, berries, water, and hot dog are blended, does a physical or chemical change occur?
both physical and chemical change occur
Does food go thought a chemical physical or both change during digestion Explain?
Both
Is melting ice a chemical or physical change explain?
It is a physical change because when you have a chemical change it changes the properties and makes it into a new thing, and it can't be reversed. Physical changes are usually just changes of states (solid, liquid, gas) and a physical change can be reversed.
Alternate Wordings for 'What is chemical change and physical change and give its examples?
Explain the difference between chemical change and physical change, and provide examples of each. Define chemical change and physical change, and provide examples to illustrate. Differentiate between chemical change and physical change, and give examples to clarify the distinction.
In a candle explain both changes using the big idea of energy?
When a candle is burnt a physical AND chemical change takes place. Its a physical change when the wax is being melted because the chemical structure has not change, meaning it cannot be a chemical change. Its also a chemical change because you are burning the string. When you burn something the chemical structure DOES change, meaning it is a chemical change.
Need help on science homework has anyone answered this question Are the changes from a to b and from b to c physical or chemical changes explain your answer?
The changes from A to B and from B to C are physical changes. Physical changes do not alter the chemical composition of the substances involved. In this case, the changes are likely related to states of matter or physical appearance, rather than chemical composition.
Is stone breaking a physical change?
Breaking of stone is a physical or chemical change? Explain.
How does phenomenon occur?
Phenomena occur as a result of physical, chemical, or biological processes acting within a given system. These processes can involve interactions between different components, such as particles, cells, or molecules, leading to observable events or behaviors. The study of phenomena aims to explain their underlying mechanisms and principles.
