What else can I help you with?
What item made by humans that can be broken down by the agents of physical and chemical weathering?
Plants and animals and ice and frost
How do plants get carbon dioxide?
Most plants have special structures on their leaves called stomates. Carbon dioxide is drawn into the leaf tissue through these pore-like structures.
What gas is released by living things to the air that is utilized by plants?
Carbon Dioxide. Animals exhale carbon dioxide as a product of respiration. Plants principally utilise carbon dioxide and produce oxygen through photosynthesis. Plants may also respire in the absence of adequate sunlight, which is why keeping plants in the bedroom is not always a good idea.
What are some differences of physical weathering and chemical weathering?
Physical weathering is due to: rocks hitting other rocks causing them to break up from the action of frost and ice the action of wind or waves or running water the action of plants. Chemical weathering changes the composition of the rock and is due to: water dissolving minerals in the rock oxidation of metals in the rock
What is used by plants to make food?
Plants use carbon dioxide, light, and water to produce (photosynthesise) "food" in the form of simple sugars - basically glucose. These sugars are normally stored as starch and are a form or chemical energy
Is plants using carbon dioxide and water to form oxygen and sugar a chemical or physical change?
Physical changes
When carbon dioxide in air converts to more complex molecules by plants during photosynthesis is that a physical change?
No, the process of carbon dioxide being converted into more complex molecules by plants during photosynthesis is a chemical change, not a physical change. Chemical changes involve the formation of new substances with different chemical properties, whereas physical changes only affect the physical state of a substance without altering its chemical composition.
Are chemicals from plants physical or chemical weathering?
Is chemicals from plants chemical weathering or physical weathering
What is photosynthsis reaction?
Photosynthysis is a plants way of changing light into food and/or carbon dioxide for the plant
What chemical form do plants need?
water and carbon dioxide
What chemical do plants use from the air?
This is the gas carbon dioxide.
What is the main chemical pollutant released by power plants and industries?
Carbon dioxide (but not from nuclear plants)
What is a chemical process that uses light to produce carbon dioxide and plants?
Photosynthesis is the chemical process that uses light to process carbon dioxide in plants.
What are the three weathering?
The three types of weathering are physical, chemical, and biological. Physical weathering involves the breakdown of rocks into smaller pieces without changing their composition. Chemical weathering occurs when minerals in rocks are dissolved or altered by chemical reactions. Biological weathering is the breakdown of rocks by living organisms like plants or animals.
Is forest fire a chemical change?
Yes, a forest fire is a chemical change because it involves the combustion of organic matter present in trees and plants, resulting in the release of heat, light, and various gases like carbon dioxide and water vapor.
Does photosynthesis involve a physical or chemical change?
Photosynthesis involves a chemical change.
Which physical process weathers rock?
Physical weathering is the process by which rocks are broken down into smaller pieces without changing their chemical composition. This can occur through processes such as freeze-thaw cycles, abrasion from wind and water, and root wedging by plants.
