What are the 7 agents of mechanical weathering?
Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion.
What is the 5 mechanical weathering?
There are five major types of mechanical weathering: thermal expansion, frost weathering, exfoliation, abrasion, and salt crystal growth.

What are the 4 types of weathering?
There are four main types of weathering. These are freeze-thaw, onion skin (exfoliation), chemical and biological weathering.
What is the most common type of mechanical weathering?
freeze-thaw cycle The most common form of mechanical weathering is the freeze-thaw cycle. Water seeps into holes and cracks in rocks. The water freezes and expands, making the holes larger. Then more water seeps in and freezes.
Which is the most common type of mechanical weathering?
freeze-thaw cycle The most common form of mechanical weathering is the freeze-thaw cycle. Water seeps into holes and cracks in rocks. The water freezes and expands, making the holes larger. Then more water seeps in and freezes.
What are the 5 causes of weathering?
Weathering can be caused by wind, water, ice, plants, gravity, and changes in temperature.
What are the 3 types of weathering?
Weathering is the breakdown of rocks at the Earth's surface, by the action of rainwater, extremes of temperature, and biological activity. It does not involve the removal of rock material. There are three types of weathering, physical, chemical and biological.
What are the 6 causes of weathering?
Weathering can be caused by wind, water, ice, plants, gravity, and changes in temperature.
What are 3 types of mechanical weathering?
The following are the types of mechanical weathering: Freeze-thaw weathering or Frost Wedging. Exfoliation weathering or Unloading. Thermal Expansion.
Which of the following is a type of mechanical weathering?
There are four main types of mechanical weathering: frost wedging in which rocks are broken by water freezing within cracks, salt crystal growth in which rocks are broken by salt freezing within cracks, sheeting in which rocks dome upward and peel off, and biological activity in which living things such as tree roots …
Which of the following are examples of mechanical weathering?
Examples of mechanical weathering include frost and salt wedging, unloading and exfoliation, water and wind abrasion, impacts and collisions, and biological actions. All of these processes break rocks into smaller pieces without changing the physical composition of the rock.
What are the 4 types of chemical weathering?
Types of Chemical Weathering
- Carbonation. When you think of carbonation, think carbon! …
- Oxidation. Oxygen causes oxidation. …
- Hydration. This isn't the hydration used in your body, but it's similar. …
- Hydrolysis. Water can add to a material to make a new material, or it can dissolve a material to change it. …
- Acidification.
How many weathering are there?
There are three types of weathering, physical, chemical and biological.
