The process of rock breaking down physically without chemical change is known as physical weathering. This occurs through mechanisms such as freeze-thaw cycles, where water seeps into cracks, freezes, expands, and ultimately causes the rock to fracture. Other processes include abrasion from wind or water, thermal expansion and contraction from temperature changes, and biological factors like root growth. These processes disintegrate rocks into smaller pieces without altering their mineral composition.

The process of breaking down food into usable materials?
Digestion is the process of breaking down food into usable materials, and is one function of the digestive system. The other function, absorption, makes these materials available to all cells in the body.
What is the term that refers to substances that can Not be broken down physically or chemically?
Matter
Which term refers to substances that cannot be broken down physically or chemically?
An alloy.
What chemically alter the nutrients changing them into a form that can be readily used by cells?
The process of digestion involves enzymes breaking down nutrients from food into smaller molecules that can be absorbed by cells. Enzymes such as amylase, protease, and lipase play a crucial role in this process by breaking down carbohydrates, proteins, and fats into forms that can be readily used by cells for energy and other functions.
What breaks down food chemically?
Enzymes are responsible for breaking down food chemically. They catalyze chemical reactions that break down complex nutrients into simpler molecules that can be absorbed by the body for energy or other purposes.
The process of breaking down food into usable materials?
Digestion is the process of breaking down food into usable materials, and is one function of the digestive system. The other function, absorption, makes these materials available to all cells in the body.
What are the two ways you can digest your food?
Digestion is accomplished by physically breaking down, or chemically breaking down foods.
What is wheatering?
weathering is the breaking down of rocks to form soil. it can be caused physically chemically or biologically. physically by ice, water, and other physical conditions chemically by solution, carbonation, hydration etc.. and biologically by human activities, animals or even plants
What does break up waste material mean?
Breaking up waste material refers to the process of physically or chemically breaking down large waste items or compounds into smaller, more manageable pieces. This can aid in the decomposition or recycling of the waste material, making it easier to process and dispose of in an environmentally friendly manner.
What is the one word that physically and chemically breaks food?
Chewing physically breaks food, while the saliva chemically breaks it down.
Where in the digestive system will a physical change occur?
The stomach uses chemicals along with muscles grinding the food back and forth breaking it down physically and chemically.
What are the steps of weathering?
Weathering involves the breaking down of rocks and minerals on the Earth's surface. The steps of weathering include mechanical weathering, which breaks down rocks physically through processes like freezing/thawing and abrasion; and chemical weathering, which alters rocks chemically through processes like oxidation and dissolution. Over time, these processes can lead to the formation of soil and sediment.
What is the term that refers to substances that can Not be broken down physically or chemically?
Matter
Which term refers to substances that cannot be broken down physically or chemically?
An alloy.
Chewing your food is a chemical breakdown true or false?
Chewing your food is only physically breaking down the substance or object by breaking it up into smaller pieces. It is only chemically broken down when it enters the stomach acids. thank u! me and my friend were arguing about it in science class.
What is the difference between a detritivore and a decomposer in terms of their roles in breaking down organic matter?
Detritivores consume and break down dead organic matter, while decomposers primarily break down organic matter into simpler substances through chemical processes. Detritivores physically consume the material, while decomposers chemically break it down. Both play important roles in the decomposition process.
What does breaking food down chemically mean?
Breaking food down chemically refers to the process of digestion, where complex food substances are converted into simpler molecules through chemical reactions. This involves the action of enzymes and acids that break down carbohydrates, proteins, and fats into their basic components—such as sugars, amino acids, and fatty acids—allowing the body to absorb and utilize these nutrients effectively. This process is essential for converting food into energy and building blocks for growth and repair.
