What are 2 factors that affect the rate of weathering?
The most important factors that determine the rate at which weathering occurs are the type of rock and the climate. Rainfall affects the rate of weathering.
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.
What are the five agents of chemical weathering?
Chemical reactions break down the bonds holding the rocks together, causing them to fall apart, forming smaller and smaller pieces. Chemical weathering is much more common in locations where there is a lot of water. This is because water is important to many of the chemical reactions that can take place. Warmer temperatures are also more friendly to chemical weathering. The most common types of chemical weathering are oxidation, hydrolysis and carbonation.
What chemical weathering process occurs when chemicals combine with water in a chemical reaction to change the physical properties of the rock?
Since igneous rocks form at high temperatures, and under pressure conditions ranging from one to several atmospheres. However, the conditions at the Earth's surface are somewhat different than the conditions at which most rocks and minerals form. Therefore, the materials are no longer at equilibrium when they are exposed to surface conditions. Under these conditions, there is a tendency for all ordered systems to seek lower levels of energy or order. This is all done through weathering. Weathering - the disintegration and decomposition of rock at or near the surface of the earth. It affects the rocks in place and no transport is involved. This distinguishes weathering from erosion.Mechanical/physical weathering - physical disintegration of a rock into smaller fragments, each with the same properties as the original. Occurs mainly by temperature and pressure changes.Chemical weathering - process by which the internal structure of a mineral is altered by the addition or removal of elements. Change in phase (mineral type) and composition are due to the action of chemical agents. Chemical weathering is dependent on available surface for reaction temperature and presence of chemically active fluids. Smaller particle sizes weather by chemical means more rapidly than large particles due to an increase of surface area. Look at the diagram below and you will see that as the particles get smaller, the total surface area available for chemical weathering increases.
Would a gargoyle be a result of physical weathering?
When a gargoyle is weathered by rain it is chemical weathering. This is because rain is slightly acid in most cases and Gargoyles are made from limestone.This is what happens:Limestone is made of calcium carbonateAcidic rain reacts with calcium carbonate.One of the products is Carbon Dioxide.The other product is Calcium, which dissolves and is washed away.So the limestone weathers.Whenever a chemical reaction takes place to result with a weathered object it is a chemical reaction.
What are the most important factors chemical weathering?
The most important factors in chemical weathering are water and carbon dioxide.THIS IS TRUE
What are the most important factors that determine the rate of weathering rock?
The most important factors that determine the rate of weathering rock are the composition and fabric of the rocks and the physical and chemical environment to which the surface of the rock is exposed.
The most of important factors in determining the rate of weathering are what?
The most important factors that determine the rate at which weathering occurs are the type of rock and the climate. Rainfall affects the rate of weathering.
Is the most important agent of chemical weathering abrasion?
no
The most important agent of chemical weathering?
Water
The most important agent of chemical weathering is .?
water
Factors that affect rates of weathering (climate)?
Two key factors affect the rates of weathering rock type and climate. Climate: is the single, most important factor that affects the rate of weathering. Chemical reactions occurs faster at higher temperatures, Warm climates favor chemical weathering, cold climates favor mechanical weathering(principally freezing and thawing), more moisture, or precipitation present, the more noticeable weathering.
Is wind the most important part in chemical weathering?
No, it's not true.
What does temperature have to do with chemical weathering?
An increase in temperature will speed chemical reactions. Therefore, in an environment where all other factors are equal, the environment with the highest temperature will have the most rapid chemical weathering of rock.
What are the two most important forces in chemical weathering?
water and carbon dioxcide
What two climate factors are most important in the weathering process?
Climate & Moisture
What is it called when chemical reactions dissolve the minerals in rock or change them into different minerals?
It's called dissolution, a form of chemical weathering.
