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
What else can I help you with?
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 are some similarities and differences between physical and chemical weathering?
Similarities: Both processes result in the breakdown of rocks and minerals. Both can occur through natural processes like temperature changes, water, and biological activity. Differences: Physical weathering involves the physical breakdown of rocks into smaller pieces without changing their chemical composition, while chemical weathering alters the chemical composition of rocks through reactions with substances like water or acids. Physical weathering does not involve chemical reactions, while chemical weathering does.
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.
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
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.
What are synonyms of physical weathering?
Some synonyms for physical weathering are mechanical weathering and disintegration.
What type of weathering is there?
phisical weatheringchemical weatheringandBiological Weathering
What type of weathering causes acid rain?
Chemical weathering causes acid rain. When sulfur dioxide and nitrogen oxides are released into the atmosphere from human activities, they combine with water vapor to form sulfuric acid and nitric acid, which then fall to the earth's surface as acid rain.
What are some similarties between chemical and physical weathering?
Chemical and physical weathering both involve the breakdown of rocks into smaller particles. Both processes are influenced by factors like temperature, moisture, and the type of rock being weathered. Additionally, both types of weathering contribute to soil formation by breaking down rocks into mineral particles.
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 is the type of weathering that involes a chemical change in some of the minerals in a rock?
Chemical weathering is the type of weathering that involves a chemical change in some of the minerals in a rock. This process breaks down the rock into smaller pieces by altering its mineral composition through chemical reactions with substances like water, oxygen, or acids.
What is the natural process that causes rock to breakdown?
Weathering from mechanical and chemical means is the process that causes rocks to become smaller and smaller; wind, rain, the sun, the freeze/thaw cycle, moving glaciers, chemical reactions, and gravity are some of the causes of weathering.
