What are rocks that have been worn away or broken up by chemical biological or physical processes called?
Rocks that have been worn away or broken up by chemical, biological, or physical processes are called "sedimentary rocks." These processes, known as weathering and erosion, lead to the breakdown of pre-existing rocks into smaller particles, which can then accumulate and eventually lithify into sedimentary formations. Examples of sedimentary rocks include sandstone, limestone, and shale.

Is mending a broken bone a physical change?
Healing a broken bone involves a combination of physical and chemical changes. The bone undergoes physical changes as it reconnects and reforms its structure, while chemical processes occur to help repair and strengthen the bone tissue.
What are two processes that results in rocks being broken down into smaller pieces?
chemical and physical weathering
What is it called when large masses of rock are broken down into smaller pieces?
The process of breaking down large masses of rock into smaller pieces is called weathering. This can occur through physical, chemical, or biological processes. Physical weathering involves the mechanical breakdown of rocks, while chemical weathering alters the minerals within the rocks. Together, these processes contribute to the formation of soil and sediment.
How does a stone get weathered?
A stone gets weathered through a combination of physical, chemical, and biological processes. Physical weathering occurs when rocks are broken down into smaller pieces by factors like wind, water, and temperature changes. Chemical weathering happens when the minerals in the rock react with water or gases in the atmosphere. Biological weathering involves organisms like lichens and plant roots breaking down the rock.
What is weathered rock made of?
Weathered rock is made up of minerals and organic materials that have broken down from the parent rock due to physical, chemical, or biological processes. This can include smaller rock particles, clay minerals, and decomposed organic matter, depending on the type and degree of weathering.
The process by which rock materials are broken down by the action of physical or chemical processes?
weathering
Rocks are broken down into sediment during what?
Rocks are broken down into sediment during the process of weathering, which involves various physical, chemical, and biological processes breaking down and disintegrating rocks into smaller particles. This can happen due to factors like temperature changes, water, wind, and biological activity.
How would you differentiate the effect of physical hazard from biological hazard and chemical hazard?
physical hazard affects you physically but a biological or chemical hazard affect you from within. Physical hazards may cause injuries such as broken leg, cuts, wounds, etc. while biological/chemical hazards can cause injuries such as choking, inability to breath, internal bleeding .

What lead to weathering?
Weathering is caused by a combination of physical, chemical, and biological processes that break down rocks and minerals at Earth's surface. Physical weathering happens when rocks are broken down by physical forces like water, wind, or temperature changes. Chemical weathering occurs when minerals in rocks undergo chemical reactions that weaken or dissolve them. Biological weathering involves the actions of living organisms like plants or bacteria that can break down rocks.
What are the forces that cause weathering?
Weathering is primarily caused by three main forces: mechanical weathering, chemical weathering, and biological weathering. Mechanical weathering occurs when rocks are broken down into smaller pieces through physical processes such as freezing and thawing. Chemical weathering involves the breakdown of rocks through chemical reactions, such as oxidation and hydrolysis. Biological weathering is caused by living organisms, which can break down rocks by their growth, burrowing, or through chemical processes.
What weathering occurs when rocks are broken apart by physical processes?
Mechanical weathering occurs when rocks are broken apart by physical processes such as frost wedging, root wedging, or abrasion. These processes break down rocks into smaller fragments without altering their chemical composition.

What does weathing mean?
"Weathering" refers to the process by which rocks and minerals are broken down into smaller pieces through physical, chemical, or biological means. Physical weathering involves the mechanical breakdown of rocks without changing their chemical composition, while chemical weathering alters the minerals within the rocks through chemical reactions. Biological weathering occurs when living organisms contribute to the breakdown, such as roots growing into cracks. Together, these processes shape the Earth’s landscape and contribute to soil formation.
