Would the action of water salt and air on car fenders be mechanical and chemical weathering?
Yes, the action of water, salt, and air on car fenders would primarily be classified as chemical weathering. Water and salt can cause oxidation and corrosion on the metal surface of the fender, while exposure to air can facilitate these chemical reactions. Over time, this chemical weathering can lead to rust and deterioration of the fender.

How do chemical weathering processes differ from mechanical weathering processes?
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.
The type of weathering caused by physical means is what type of weathering?
The type of weathering caused by physical means is called mechanical weathering. It involves the physical breakdown of rocks into smaller fragments without changing their chemical composition. Examples include frost wedging, abrasion, and root wedging.
What is physical weathring and Chemical weathring?
Physical weathering is different from chemical weathering because physical weathering is when a river is to weather away the rock. Chemical is when acid precipitation is too dissolve the rock.
What is a chemical or physical process in which rocks exposed to the weather are worn down by water wind or ice?
Weathering is the process in which rocks are broken down into smaller pieces by the action of water, wind, or ice. This can occur through mechanical weathering, where physical forces like pressure or temperature changes break rocks apart, or chemical weathering, where the chemical composition of rocks is altered by things like water or air.
Wind Abrasion is it physical or chemical?
Wind abrasion is a physical weathering process that occurs when wind carries small particles like sand or pebbles that collide with and wear away rocks and other surfaces over time. This mechanical action leads to the erosion and shaping of landforms in arid environments.
Is animal action mechanical or chemical weathering?
Chemical weathering
Is the action of saltwaterand air on car fenders and panels chemical or mechanical?
It's a chemical reaction
Is frost action mechanical or chemical weathering?
Frost action is a type of mechanical weathering. It occurs when water seeps into cracks in rocks, freezes, expands, and causes the rock to break apart.
Is glacier action chemical weathering or mechanical weathering?
Glacier action involves primarily mechanical weathering, as the movement of glaciers causes rocks to break apart through the physical forces of compression and abrasion. However, chemical weathering can also occur in glacial environments through processes like freeze-thaw cycles and the introduction of chemical substances from the ice.
How are mechanical weathering and chemical weathering alike and different?
The differences are that mechanical weathering is the breaking of rock into smaller pieces by forces due to gravity, corrosion, freezing (dilatation of the material) and melting of water, plant roots, or other forces. (The mechanical does it physically)So then chemical weathering is the changing of materials in a rock by chemical processes, for example acidic rains action, solubility of some components, chemical reactions, thermal decomposition, etc.
Compare and contrast mechanical weathering and chemical weathering?
Mechanical weathering provides fresh surfaces for attack by chemical processes, and chemical weathering weakens the rock so that it is more susceptible to mechanical weathering.
What does not cause mechanical weathering?
Chemical weathering, such as the reaction of rock with acids or oxidation, does not cause mechanical weathering. Mechanical weathering involves physical processes like freezing and thawing, abrasion, and root growth that break rocks into smaller pieces without altering their composition.
What are six forces that bring about the weathering of rock?
The six forces that bring about the weathering of rock are mechanical weathering (e.g. frost action, root wedging), chemical weathering (e.g. oxidation, dissolution), biological weathering (e.g. plant roots, burrowing animals), temperature changes, pressure changes, and erosion by wind, water, or ice.
Compare and contrast chemical weathering and mechanical weathering?
Mechanical weathering is taking a big rock and breaking it down to small rocks by releasing pressure, freezing and thawing (water and ice), animal action, plant growth and abrasion. Chemical weathering is when a rock loses it shape but STILL IS MADE OF THE SAME METRICAL. Chemical weathering uses water, oxygen, carbon dioxide, living organism, and acid rain.
What are characteristics of mechanical weathering?
Mechanical weathering is when rocks are worn away by physical action, ex: a river running past.
What kind of mechanical weathering its a chilly?
Chilly temperatures can contribute to mechanical weathering through the process of freeze-thaw action. When water seeps into cracks in rocks and freezes, it expands and puts pressure on the rock, causing it to crack and break apart over time.
What are 2 examples of weathering?
Two examples of weathering are mechanical weathering, such as when rocks are broken down into smaller pieces by physical forces like wind or water, and chemical weathering, which occurs when rocks are broken down by chemical reactions like oxidation or dissolving.
