How do chemical weathering processes differ from mechanical weathering processes?

∙ 13y ago
Chemical weathering processes change the mineral composition of the rock, but physical weathering processes do not. Mechanical (physical) weathering is the breakdown of rock into smaller particles due to such factors as freezing and thawing, release of pressure, water absorption salt crystal formation, landmass uplift, expansion and contraction from the sun or fire, plant root growth, actions of animals, abrasion, or other means that do not directly affect the rock's chemistry. Chemical weathering is the dissolution, carbonation, oxidation, or hydrolysis of rock and mineral by chemical means only, mostly from reactions with water or the acids contained in rainwater. Other materials are formed in the process. Warm, tropical climates are ideal environments for chemical weathering to take place as the chemical reactions are quickened by the bountiful rain and warm temperatures.

Which pair of molecules share the same chemical composition but differ in molecular structure?
Lactose and sucrose share the same chemical composition but differ in molecular structure. Such molecules are called isomers.
In what ways do metals differ from each other?
The chemical and physical properties are very different; for example: color, density, melting point, boiling point, chemical reactivity, hardness, mechanical properties, electrical conductivity, etc.
If isomers of an alkali have the same molecular formula how do they differ?
Isomers have different physical and chemical properties.
How do the reactants of a chemical reaction differ from the products of the same reaction?
They contain different combinations of particles.
Does physical change differ from a chemical in that waste products are formed through chemical changes?
Yes,physical change is different in chemical change because chemical change form a new substances or product that may arise into two substances held in chemical change
How do the products of mechanical and chemical weathering differ?
tool marks
How do products of mechanical and chemical weathering differ?
tool marks
How the rates of mechanical and chemical weathering might differ in the Congolese rain forest and the Siberian steppes?
The rates of mechanical weathering does not affect anything since the chemical properties remain unchanged. Only chemical weathering affects the chemical properties of an object.
How does the rates of mechanical and chemical weathering might differ in the Congolese rainforest and the Siberian steppes?
Rates start at 69% and higher .
What two processes of digestion begins in the mouth how do they differ?
Salivary Amylase helps digest starch while in the mouth as a chemical digestion. Chewing is another form of digestion, but its mechanical
How does weathering differ from erosion?
Weathering is a change that causes something to break down or worn away due to exposure to one or more weather elements (wind, rain, heat, etc.) over a period of time. Erosion is a change that causes something to break down or worn away due to natural processes over a period of time. Weathering is considered to be one of these natural processes that fit the definition of erosion.
What causes the rate of weathering to differ?
Weathering can break away less resistant parts of the rock and leave behind the more resistant parts.
What symptoms can chemical exposure cause?
Symptoms differ from a chemical to other.
Why dont compounds differ from mixtures?
Compounds differ from mixtures; the chemical composition is different !
Is a chemical change differ from a physical?
yes
Light and sound differ is?
Light is electrical energy and sound is mechanical energy.
How does assemblage primarily differ from other sculptural processes?
It utilizes "found" objects
