Ice weathering
Weathering is the surface process that slowly decomposes rock, breaking it down into smaller particles through physical, chemical, or biological means.
Weathering is the surface process that slowly disintegrates and decomposes rock over time. This can be due to physical processes like frost wedging or chemical processes like acid rain.
Landslide is a physical phenomenon (geological).
No, a volcanic eruption is a physical process where molten rock, ash, and gases are expelled from a volcano. It does involve the release and interaction of different chemicals, but it is not a chemical reaction in the traditional sense.
Mechanical weathering is a process which physically changes the appearance of a rock or structure. Chemical weathering is a process which changes the chemical composition of a rock or structure.
Chemical weathering is primarily driven by processes such as oxidation, hydrolysis, and carbonation. These processes involve the breakdown of rocks through chemical reactions with substances like oxygen, water, and carbon dioxide, leading to the alteration or dissolution of minerals in the rock.
Hydration is the chemical weathering process that occurs when minerals in the rock react with water to form new minerals or alter the structure of the rock. This process helps break down rock into smaller particles over time.
chemical ----------- I consider that this is a physical process.
yes
Chemical Weathering
When a large rock falls from a cliff, it primarily demonstrates mechanical weathering. This process occurs as the rock breaks apart due to physical forces, such as impact with the ground or other rocks, without altering its chemical composition. Over time, further exposure to elements like wind, water, and temperature changes may lead to additional mechanical weathering, while chemical weathering would involve changes in the rock's minerals due to chemical reactions.
This chemical process is called hydration.
