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.
The type of weathering caused by physical means is what type of weathering?
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.
What action is an example of a chemical defense in your skin?
One action is an example of a chemical defense in your skin is sweating palms. Sweaty palms are a reaction to stress, thus it's a chemical reaction.
Is stirring a chemical change?
No, it is a physical action.
What is a chemical substance that mimics the action of a neurotransmitter?
Agonists
Is animal action mechanical or chemical weathering?
Chemical weathering
Is glacier action chemical weathering or mechanical weathering?
Mechanical weathering for example freeze-thew process or abrasion.
Is the action of saltwaterand air on car fenders and panels chemical or mechanical?
It's a chemical reaction
Is frost wedging chemical weathering?
No, it's a purely mechanical action.
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.
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.
What does not cause mechanical weathering?
A mechanical action would not cause chemical weathering of rock and soil. For example, using a handheld hammer or jackhammer against a stone or rock.
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.
The abrasive action of waves is know as?
Mechanical weathering
Frost action is an example of this type of weathering.?
mechanical
Mechanical Weathering?
In mechanical weathering, rocks are broken down into smaller pieces without changing their composition. Mechanical weathering is caused by freezing and thawing, release of pressure, plant growth, action of animals, and abrasion.
