Explain whether water is a cause of either chemical weathering physical weathering or both?
Water can cause both chemical and physical weathering. In chemical weathering, water can react with minerals in rocks to break them down into new substances. In physical weathering, water can seep into cracks in rocks, freeze, and expand, creating pressure that breaks the rock apart.

What process does igneous rock have to go through to be formed into sediment?
Igneous rock undergoes weathering, where it is broken down into smaller particles by physical, chemical, or biological processes. These particles are then transported and deposited in layers by wind, water, or ice to form sediment. Over time, the sediment is compacted and cemented together to form sedimentary rock.
Sulfur has a bright yellow color is this physical or cheimical property?
Its colour, its melting point, its boiling point, whether it is magnetic or not, whether it is an electrical conductor or not and its atomic mass are all physical properties.
Where in a soil profile is solid rock being weathered into soil?
The process of solid rock being weathered into soil typically occurs in the parent material layer of the soil profile, which is the layer closest to the unaltered bedrock. Weathering processes, whether physical or chemical, gradually break down the solid rock into smaller particles to form the soil.
Explain how you can tell whether a chemical reaction has taken place?
A chemical change or reaction happens if new substances are formed. there may be a change in temperature so the reaction mixture may heat up or cool down. it also might change colour, give off bubbles of gas or fumes and you also might hear fizzing or a gas might explode.
Is water still H2O after it evaporates?
no, then it is gasEDIT: The chemical formula for pure water is always H2O - regardless of whether it's in the form of ice, water or steam ! Snakester1962 (Supervisor)

Can physical weathering make a rock bigger?
Physical weathering is mechanical action which typically erodes rock faces. This invariably results in a smaller rock. Chemical weathering involves water absorption or other reactions. Mechanical heating and freezing can crack and fissure the rock, slightly increasing its size. In general, physical weathering is an abrading process, whether via water born sediment wearing away the rock, or wind blown particles sand blasting the rock, and these actions make reduce the rock's size.
Is dissolving salt in water a a chemical change or a physical change?
It is a physical change as it can be "undone" by evaporating the water. An simple example of a chemical change is baking a cake, you can't un-bake a cake. To work out whether it is a chemical or physical change just think whether it can be undone or not.
What are the two criteria for whether a change is chemical or physical?
Oxygen and hydrogen
What would be a rule deciding whether a change is chemical or physical?
- A physical change is a change of phase or dimensions. - A chemical change is a change of the chemical structure, new molecules are formed, the initial molecule is transformed.
How does ice contribute to physical weathering?
It falls in the cracks as water and freezes. As it freezes, it expands, eroding what ever it fell into, whether its concrete or rock.
How do you decide whether an observed property of matter is a physical property?
If the property can be observed without changing the chemical composition of the substance, then it is a physical property. If the property can be observed only through a chemical reaction, then it is a chemical property.
Is rain evaporation physical or chemical?
Physical change from liquid to vapour. The water remains chemically the same whether liquid or vapour.
Is gas physical or chemical at room temp?
This question makes no sense. All substances, whether solid, liquid, or gas have both physical and chemical properties at virtually all temperatures.
How you would separate the components of a mixture and state whether your methods would be physical or chemical changes?
l,
What is the most important question to ask determine whether a change is a physical or chemical change?
did the composition change
Is breaking your arm a physical change?
I have reasons to believe it is a physical change. The appearance is different but the body functions pretty much the same way it would have. Although, there maybe a chemical change as the body adapts to having one hand. Whether the Chemical change occurs in the body or joint where the hand was previously it still doesnt explain why it shows signs of physical change as well.
