What else can I help you with?
What are four factors that affect how fast weathering happens?
the nature of the material weathered (shape, size, composition) the nature of the weathering agent the frequency of the weathering agent the properties of the surrounding environment
Can ice be an agent of chemical weathering?
No ice is an agent of physical weathering
What is the acid precipitation is an agent of weathering?
acid precipitation is an agent of -------weathering
How rocks are mechanically weatherd?
When rocks are broken down without any change to their chemical compositions it is mechanical weathering. Causes of mechanical weathering are Freezing and melting of water, Abrasion, when the rock is weather by an abrasive agent such as wind and sand, and exfoliation occurs when a rock is brought to the surface.
What is an Agent that mechanically removes contaminants from objects is?
ultraviolet
Acid precipitation is an agent of what kind of weathering?
Chemical weathering.
Is deposition an agent of weathering?
no
Why is water the major agent of chemical weathering?
Water is the major agent of chemical weathering because it can dissolve minerals in rocks, facilitating chemical reactions that break down the rocks over time. Water also provides a medium for reactions to occur and helps transport dissolved minerals away from the weathering site. The abundance and properties of water make it highly effective in altering and breaking down rocks chemically.
What are the agent of rock?
what are the agents of weathering
Why sun is agent of weathering?
The sun is not considered an agent of weathering. Weathering refers to the process of breaking down rocks and minerals on the Earth's surface, which is primarily caused by factors like water, wind, and temperature changes. The sun's energy can contribute to weathering indirectly by causing temperature changes that lead to expansion and contraction of rocks, but it is not a direct agent of weathering.
How unloading acts as a weathering agent?
Unloading acts as a weathering agent by breaking bedrock into smaller pieces. This increases the surface area along which chemical reactions can occur, which eventually leads to weathering.
How can gravity act as an agent of weathering?
If you drop a rock and it breaks into pieces, then that is an act of mechanical weathering.
