Acid rain contains sulfuric and nitric acids which react with minerals in rocks, breaking them down into smaller particles. This process, known as chemical weathering, weakens the rocks and causes them to disintegrate over time. Acid rain speeds up the natural process of weathering by facilitating chemical reactions that result in the erosion of rocks and soil.
Statement 3 does NOT describe a chemical equation. It should read: "The arrow represents the direction in which the reaction is proceeding."
The formula for the anhydrous form is Al2(SO3)3.
The chemical formula for aluminum hydroxide is Al(OH)3.
The chemical formula for gold bicarbonate is Au(HCO3)3.
Water causes mechanical and chemical weathering.
The three main types of weathering are mechanical weathering, chemical weathering, and biological weathering. Mechanical weathering involves physical processes like freezing and thawing, chemical weathering involves chemical reactions that break down rocks, and biological weathering involves living organisms breaking down rocks.
The three factors that affect weathering are mechanical weathering (physical breakdown of rocks), chemical weathering (chemical changes in rocks), and biological weathering (weathering caused by living organisms).
The three types of weathering are physical, chemical, and biological. Physical weathering involves the breakdown of rocks into smaller pieces without changing their composition. Chemical weathering occurs when minerals in rocks are dissolved or altered by chemical reactions. Biological weathering is the breakdown of rocks by living organisms like plants or animals.
1) Physical weathering can be split into 2 subgroups-Freeze Thaw and Onion Skin! 2) Chemical Weathering! 3) Biological Weathering!
The sources of weathering include physical factors like wind, water, and temperature changes, as well as chemical factors such as acids, oxygen, and organic compounds. Biological factors like plants, animals, and microbes can also contribute to weathering processes.
One cause of biological weathering is through the organism lichens. Other types are caused by plants, animals, and exposure to acids.

Mechanical weathering processes such as freeze-thaw cycles can break down rocks without water. Exfoliation weathering due to temperature changes causing rocks to expand and contract. Biological weathering by plants and animals can break down rocks without water. Chemical weathering from oxygen, carbon dioxide, and acids in the atmosphere can degrade rocks without water.
The three agents of chemical weathering are water, oxygen, and acids. Water plays a role by dissolving minerals, oxygen reacts with minerals to form oxides, and acids can break down rocks by reacting with minerals in them.
