Quick Answer: Which Of The Following Is An Example Of Chemical Weathering?

Which is an example of chemical weathering?

Chemical weathering occurs when water dissolves minerals in a rock, producing new compounds.

Hydrolysis occurs, for example, when water comes in contact with granite.

Feldspar crystals inside the granite react chemically, forming clay minerals.

The clay weakens the rock, making it more likely to break..

Which is an example of chemical weathering quizlet?

What is an example of Chemical Weathering. Acid rain raining on rocks and breaking it down from the reaction of the chemicals.

What are the five agents of chemical weathering?

Terms in this set (5)water. dissolves rock when a rock or other substance mixes uniformly throughout it to make a solution.oxygen. iron combines with this and water through the process, oxidation (rust)carbon dioxide. … living organisms. … acid rain.

What is the definition of physical weathering quizlet?

What is the definition of physical weathering? … When a rock is physically broken into smaller pieces, there is more surface area on which chemical weathering can occur. Frost wedging. expansion of ice forces a rock apart.

What are 4 examples of chemical weathering?

Types of Chemical WeatheringCarbonation. 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.

What is the process of chemical weathering?

Chemical weathering is caused by rain water reacting with the mineral grains in rocks to form new minerals (clays) and soluble salts. These reactions occur particularly when the water is slightly acidic.

What are 4 examples of erosion?

Examples of Erosion:Caves. Caves are carved out over thousands of years by flowing water, but that activity can be sped up by carbonic acid present in the water. … River Banks. … Cracks in Rocks. … Gravitation Erosion. … Coastal Erosion.

Are sinkholes an example of chemical weathering explain?

A sinkhole is a natural hole that forms in the Earth’s surface as a result of the chemical weathering of carbonate rocks like limestone, as well as salt beds or rocks that can be severely weathered as water runs through them.

What is the difference between physical and chemical weathering?

Physical, or mechanical, weathering happens when rock is broken through the force of another substance on the rock such as ice, running water, wind, rapid heating/cooling, or plant growth. Chemical weathering occurs when reactions between rock and another substance dissolve the rock, causing parts of it to fall away.

What is the best example of weathering?

Weathering is the wearing away of the surface of rock, soil, and minerals into smaller pieces. Example of weathering: Wind and water cause small pieces of rock to break off at the side of a mountain.

What are the 6 types of weathering?

Types of Mechanical WeatheringFrost Wedging or Freeze-Thaw. ••• Water expands by 9 percent when it freezes into ice. … Crystal Formation or Salt Wedging. ••• Crystal formation cracks rock in a similar way. … Unloading and Exfoliation. ••• … Thermal Expansion and Contraction. ••• … Rock Abrasion. ••• … Gravitational Impact. •••Apr 20, 2018

Which is an example of chemical weathering Brainly?

Rock breaking up due to acid rain is an example of chemical weathering because the carbon dioxide in the acid rain triggers a chemical reaction in the rock, as the carbonic acid in the acid rain (H2CO3) interacts with the calcium carbonate (CaCO3) and these leads tot he formation of new substances including calcium …

Which of the following is the best example of chemical weathering?

Limestone rocks dissolving in water Plant roots growing through concrete and splitting it Waves carrying sand away from a beach A large rock splitting into pieces because of ice.

What are 5 examples of weathering?

These examples illustrate physical weathering:Swiftly moving water. Rapidly moving water can lift, for short periods of time, rocks from the stream bottom. … Ice wedging. Ice wedging causes many rocks to break. … Plant roots. Plant roots can grow in cracks.

Is rust an example of chemical weathering?

Oxidation is another kind of chemical weathering that occurs when oxygen combines with another substance and creates compounds called oxides. Rust, for example, is iron oxide.

Which of the following is an example of chemical weathering Brainly?

Answer Expert Verified An example of chemical weathering is an acid dissolving limestone. This is because an acid is a product of industrial and chemical processes that is used in a lot of commercial practices.
