Mechanical, chemical, and biological weathering break rocks into small pieces. Mechanical weathering occurs when temperature changes cause rocks to expand and contract, cracking them. Chemical weathering happens when gases in rainwater dissolve minerals in rocks. Biological weathering is carried out by roots, burrowing animals, and humans breaking rocks apart. All rocks on Earth will eventually weather due to these exogenic forces.
Chemical and biological weathering lesson 5
Chemical weathering involves the breakdown of rocks through chemical processes involving water and atmospheric gases. The main types of chemical weathering are oxidation, hydration, hydrolysis, carbonation, and solution. These processes weaken rocks through reactions with water and acids. Chemical weathering is common in warm, humid climates and produces dull, pitted rock surfaces.

Weathering breaks rocks down into smaller pieces over time through mechanical, chemical, and biological processes. Mechanical weathering is caused by temperature changes that make rocks expand and contract, cracking them. Water freezing in these cracks also breaks rocks apart. Chemical weathering occurs as rainwater reacts with minerals in rocks. Biological weathering results from plant roots and small creatures breaking up rocks to make space in cracks. All of these types of weathering break rocks into smaller pieces that eventually become soil.
Weathering
Rocks break down into soil through two types of weathering: mechanical and chemical. Mechanical weathering physically breaks rocks into smaller fragments through forces like water, wind, temperature changes, and the action of living things. Chemical weathering alters the composition of rocks through chemical reactions involving water and other agents, transforming their ingredients and eventually forming soil over time.
Presentation of chemical weathering
Chemical weathering is caused by reactions between rainwater and rock minerals that form new minerals and soluble salts. These chemical processes include oxidation, hydrolysis, and solution (carbonation). They occur most rapidly in warm, damp climates and are the first stage in soil production. The most important types are oxidation, hydrolysis, solution, and carbonation. Oxidation involves reactions with oxygen that alter mineral composition. Hydrolysis produces clay and salts through reactions with acid rain. Solution dissolves minerals like limestone in acidic rainwater. Carbonation is the reaction of carbonic acid, formed when carbon dioxide and water combine, dissolving minerals like limestone.
Biological weathering
Biological weathering is the breakdown of rocks through the action of living organisms like plants, animals, and microbes. It occurs as roots penetrate rocks to absorb water and nutrients, thereby exerting pressure that cracks rocks apart over time. Microbes and lichen also contribute through chemical reactions, secreting acids or chelating compounds that dissolve rock minerals. While the forces are small, continual effects from a wide variety of organisms gradually cause mechanical and chemical weathering of surface rocks.
Weathering & it's types
This document defines and describes the main types of weathering processes that occur at the Earth's surface: mechanical, chemical, and biological. Mechanical weathering involves physical breakdown through processes like frost wedging and abrasion without changing the rock's chemical composition. Chemical weathering decomposes rocks through reactions with substances like carbon dioxide, water, and oxygen. Biological weathering disintegrates rocks through organism activities like plant roots, lichen/algae growth, and burrowing. Different rock types and climates result in variable weathering rates.
Chemical weathering
Chemical weathering occurs when rocks chemically decompose through processes like oxidation and carbonation. Oxidation involves oxygen reacting with iron in rocks to form rust, which breaks the rocks down. Carbonation is the reaction of carbon dioxide and water to form carbonic acid, which dissolves minerals in rocks and helps form caves. Chemical weathering alters rocks through chemical breakdown when combined with water or acids.

2.2 weathering and erosion
Plants and animals contribute to mechanical weathering by enlarging cracks in rocks. As tree roots grow, they widen existing cracks in rocks and eventually break them into pieces. Even small plants like mosses can enlarge cracks as they grow. Animals that burrow, such as moles and prairie dogs, also help break up rock and soil as they tunnel underground. Other animals cause additional cracking and crumbling of rock through digging and trampling above ground over time.

The document also mentions producers, consumers, soil erosion from clearing land, pollution from wastewater, the ozone layer blocking ultraviolet rays, and individual responsibility in garbage disposal.
Weathering and Erosion for Class
Weathering breaks down rocks into smaller pieces through physical or chemical processes. Physical weathering breaks rocks mechanically through frost wedging, plant roots, friction, temperature changes, and animal burrowing. Chemical weathering uses chemical reactions like oxidation and acidification to break rocks down. Common agents of chemical weathering include water, oxygen, carbon dioxide, living organisms, and acid rain. Erosion then transports these weathered materials through water, ice, wind, or gravity.
Biological Weathering
This document discusses biological weathering, which is the breakdown of rocks and other materials caused by living organisms. It occurs through both mechanical and chemical means as organisms interact with rocks. The main causes of biological weathering are: 1) man and animals through activities like construction and burrowing; 2) higher plants and their roots, which can penetrate cracks and exert disruptive force; 3) microorganisms like bacteria, fungi, and mosses that extract nutrients and produce compounds aiding decomposition. An advantage is that biological weathering creates nutrient-rich soil allowing plant growth, though it can also cause rock instability.
Weathering of Rocks
Weathering is the process by which rocks break down and decompose on Earth's surface over time due to physical and chemical processes. There are three main types of weathering: physical, chemical, and biological. Physical weathering occurs through temperature changes that cause rocks to expand and contract, eventually breaking them down. Chemical weathering involves reactions between rainwater and minerals that form new compounds and dissolve parts of the rocks. Biological weathering is caused by plant and animal life burrowing, growing, and decomposing, which further breaks rocks into smaller pieces or sediments. Weathering provides advantages to humans such as soil formation and minerals used for construction and mining.
Weathering and Erosion
Weathering is the breakdown of rocks and other materials caused by contact with the atmosphere, water, and living things. There are three main types of weathering: physical, chemical, and biological. Physical weathering breaks rocks through temperature changes and frost action without changing the chemical composition. Chemical weathering alters the chemical makeup of rocks through reactions with water and acids. Biological weathering involves acids released by plants and microbes interacting with minerals.
Exogenic Processes
Exogenic processes refer to activities that occur on Earth's surface, including weathering, soil formation, and erosion. Weathering breaks down rocks through mechanical or chemical means, reducing their size and preparing materials for transport. Mechanical weathering breaks rocks down physically by forces like wind, water, and gravity, while chemical weathering involves reactions with substances like water, carbon dioxide, and oxygen that alter the rocks' composition. Erosion then transports weathered materials from one place to another using natural elements such as moving water, wind, gravity, and animals. Over time, this leads to the formation of soil in areas with suitable conditions.

Weathering.pptx
Chemical weathering is more useful in soil formation than mechanical weathering because:
- Chemical weathering changes the minerals in rocks and causes new substances to form. This releases nutrients from the rocks that plants can use.
- Mechanical weathering only breaks rocks into smaller pieces through physical processes like temperature changes, abrasion, etc. but does not release as many nutrients.
- The new substances formed during chemical weathering like carbonic acid help dissolve more rocks and release more nutrients into the soil over time compared to mechanical weathering alone.
- Released nutrients are important for plant growth. As more plants grow, they add more organic matter to the soil through their remains. Organic matter is a key component of healthy
