What are some differences of physical weathering and chemical weathering?
RYANJACOBESENAMAZING
Physical weathering is due to:
rocks hitting other rocks causing them to break up
from the action of frost and ice
the action of wind or waves or running water
the action of plants.
Chemical weathering changes the composition of the rock and is due to:
water dissolving minerals in the rock
oxidation of metals in the rock

∙ 11y agophysical weathering is about rocks and chemical weathering is about is about chemicals hahah lol
Wiki User
∙ 11y agophysical weathering is when waves or wind beats it down by pressure. chemical weathering is when it uses chemicals to break down rocks
Wiki User
∙ 8y agoThat physical weathering can be caused my pressure changes and chemical weathering is caused by rocks falling

Can you give me some notes about weathering?
There are two types of weathering: chemical and physical. Chemical weathering is said to occur when the chemical compounds of rocks are changed. Physical weathering happens due to wind, rain, or other natural occurrences.
What is an agent of chemical weathering?
Agents of chemical weathering depend on the climate and composition of the rock that is breaking down. Some Agents would include, water, oxygen, CO2, and acids. Temperature plays a significant role in chemical weathering. If it is warm and wet, the Chemical weathering process will increase. So, really it all depends.
Are all physical differences caused by genetic differences?
No. Some can be caused are caused by nurture: health - including diet and diseases.
Is a tin can rusts a physical or chemical change?
Yes, it is, because the chemical composition of the outside changes due to oxydation.
Is Stomach acid dissolving pizza a physical or chemical change?
There are some chemical aspects:base is made from flour and yeast,so the reaction between them is a chemical change.The cooking of the pizza is also a chemical reaction, because it cannot be undone.There are also some physical aspects, e.g.Making the doughgrating the cheesemelting the cheese

What type of weathering causes acid rain?
carbonation is an example of chemical weathering carbonation is an example of chemical weathering
What type of weathering is there?
phisical weatheringchemical weatheringandBiological Weathering
Compare and contrast mechanical weathering and chemical weathering?
Mechanical weathering provides fresh surfaces for attack by chemical processes, and chemical weathering weakens the rock so that it is more susceptible to mechanical weathering.
How are physical and chemical weathering different?
Physical weathering is when some liquid like wind or water over a long period of time breaks of the outer layers of and object, like a rock. Chemical weathering is when an acid or something else chemically eats away at an object like a rock, happening at a much faster rate. Physically weathering - water eroding a rock Chemical weathering - coca cola acids eating away at the rust of a nail. Hopefully this helped
Is erosion chemical weathering?
No. Erosion usually involves the transportation of material from one place to another place. Chemical weathering involves the reaction of natural Earth materials with acidic fluids, causing dissolution.
What is the type of weathering that involes a chemical change in some of the minerals in a rock?
Chemical weathering
How are mechanical weathering and chemical weathering alike and different?
The differences are that mechanical weathering is the breaking of rock into smaller pieces by forces due to gravity, corrosion, freezing (dilatation of the material) and melting of water, plant roots, or other forces. (The mechanical does it physically)So then chemical weathering is the changing of materials in a rock by chemical processes, for example acidic rains action, solubility of some components, chemical reactions, thermal decomposition, etc.
What is the diffence between chemical weathering and physical weathering?
Chemical and biological weathering are different because: a) biological weathering - this means that if a seed of a plant gets coincidentally deposited in a crack in a rock, if it is humid enough, the see will grow. it's roots will spread out and eventually break the rock. b) chemical weathering - this means that chemicals in rain/acid rain weathers away the rock.
What are the different types of weathers?
Mechanical weathering, Biological weathering and Chemical weathering.
Differences between physical and chemical changes?
A physical change is a change that does not change the chemical makeup of the substance. This can be crushing, tearing, or a phase change for example. A chemical change changes the chemical makeup of the substance. Some examples of this are rusting, combustion, or digestion.
Some agents for chemical weathering?
OxygenFreezing and thawing
