Ice wedging is an example of which type of weathering?
Mechanical Weathering
What are non-examples of mechanical weathering?
Mechanical weathering is physical changes that break down and/or cracks the rock, such as ice wedging, temperature changes, root growth, or animal activity. Chemical weathering is a chemical change that changes the chemicals of the substance to make a new one. Examples of chemical weathering include oxidation, acid rain, hydration, and carbonation.
What is rain an example of?
Chemical weathering
What chemical weathering process occurs when chemicals combine with water in a chemical reaction to change the physical properties of the rock?
Since igneous rocks form at high temperatures, and under pressure conditions ranging from one to several atmospheres. However, the conditions at the Earth's surface are somewhat different than the conditions at which most rocks and minerals form. Therefore, the materials are no longer at equilibrium when they are exposed to surface conditions. Under these conditions, there is a tendency for all ordered systems to seek lower levels of energy or order. This is all done through weathering. Weathering - the disintegration and decomposition of rock at or near the surface of the earth. It affects the rocks in place and no transport is involved. This distinguishes weathering from erosion.Mechanical/physical weathering - physical disintegration of a rock into smaller fragments, each with the same properties as the original. Occurs mainly by temperature and pressure changes.Chemical weathering - process by which the internal structure of a mineral is altered by the addition or removal of elements. Change in phase (mineral type) and composition are due to the action of chemical agents. Chemical weathering is dependent on available surface for reaction temperature and presence of chemically active fluids. Smaller particle sizes weather by chemical means more rapidly than large particles due to an increase of surface area. Look at the diagram below and you will see that as the particles get smaller, the total surface area available for chemical weathering increases.
Describe two ways chemical weathering may occur?
1. Chemical Weathering: Where different chemicals such as acid rain react with soft stone such as chalk and dissolves it away causing weathering. 2. Biological Weathering : Where organisms such as trees have an effect of rocks due to their roots breaking away at them when they grow through the soils underneath.
How is hydrolysis weathering different from hydration weathering?
hydrolisis is the chemical breakdown of rocks as they react with water where as hydration is the breakdown of rocks as they absorb water.
What type of weathering is where rock is broken down as it absorbs water?

What chemical weathering process occurs when chemicals in a rock combine with water to form a new substance?
This chemical process is called hydration.
What is the differences between physical weathering and chemical weathering of granite?
Physical weathering is: frost, crystallization, exfoliation,, biological and pressure release. Chemcal weathering: anything with chemicals in it like carbonation, hydrolysis, solution, oxidation and hydration.
The process of weathering that occurs when rocks and minerals react chemically with water and atmospheric gases is?
Hydration
What type of weathering is hydrolysis?
Hydrolysis is a type of chemical weathering, which includes oxidation, reduction, carbonation, solution, and hydration. If water and a compound meet together, hydrolysis is the reaction that occurs.
