Ice wedging is an example of which type of weathering?
Mechanical Weathering
What is rain an example of?
Chemical 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 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.
What is a type of weathering where rock is broken down as absorbs water?
Hydration
What type of weathering is where rock is broken down as it absorbs water?
Hydration
What is a type of weathering where rock is broken down as is absorbs water?
Hydration
How is hydrolysis weathering different from hydration weathering?
Hydrolysis weathering involves the breakdown of minerals due to the reaction with water, leading to the formation of new minerals. Hydration weathering, on the other hand, refers to the absorption of water molecules into the mineral structure, causing a physical expansion and potentially leading to weakening and disintegration of the mineral.
What are the types of Chemical Weathering?

What chemical weathering process occurs when chemicals in a rock combine with water to form a new substance?
This chemical process is called hydration.
Is the most important agent of chemical weathering abrasion?
No, the most important agent of chemical weathering is typically water. Water helps break down rocks through processes like hydration, hydrolysis, and oxidation. Abrasion, which is the physical wearing down of rocks by friction and impact, is an example of mechanical weathering rather than chemical weathering.

Which of the following processes is an example of chemical weathering?
Which of the following is an example of chemical weathering?
How does mineral composition affect rate and type of weathering?
Mineral composition affects the rate and type of weathering because some minerals are more resistant to weathering processes than others. For example, minerals like quartz are more resistant to chemical weathering than minerals like calcite. The presence of certain minerals can also influence the types of weathering processes that occur, such as hydration, hydrolysis, oxidation, and dissolution. Overall, the mineral composition of a rock or mineral determines its susceptibility to weathering.
Which is most common in the desert mechanical or chemical weathering?
Chemical weathering is more common in deserts, as the dry conditions limit the amount of mechanical weathering that can occur. Chemical weathering processes such as oxidation, hydration, and dissolution are more prevalent in desert environments where water is scarce.
