What factors determine a rocks response to stress?
What factors determine a rocks response to stress?
A rock’s response to stress depends on the rock type, the surrounding temperature, and pressure conditions the rock is under, the length of time the rock is under stress, and the type of stress.
What are four factors that influence the strength of a rock and how it will deform?
Factors that influence the strength of a rock and how it will deform include temperature, confining pressure, rock type, and time. Stress is the force per unit area acting on a solid.
What are the four factors that influence rock strength?
The factors that influence the strength of a rock and how it will deform include temperature, confining pressure, rock type, and time.
What are the factors that can affect rock formation?
These factors include: 1) Mineral composition structure and texture of solid rocks: 2) Rock mass structure which is determined by bedding and jointing and underlies spatial nonhomogeneity or, in other words, anisotropy of strength; 3)Water content; 4)State of stress which reflects structural features of gravitational …
What are the five factors of weathering?
Factors affecting weathering
- rock strength/hardness.
- mineral and chemical composition.
- colour.
- rock texture.
- rock structure.
What are the two factors that affect the rate at which weathering occurs?
There are two factors that play in weathering, viz. Temperature and Precipitation. Warm climates affect by chemical weathering while cold climates affect by physical weathering (particularly by frost action). In either case the weathering is more pronounced with more moisture content.
What are two factors that affect the rate of weathering?
Rainfall and temperature can affect the rate in which rocks weather. High temperatures and greater rainfall increase the rate of chemical weathering.
What are the two most important factors that determine the rate of weathering?
The most important factors that determine the rate at which weathering occurs are the type of rock and the climate.
What are four causes of mechanical weathering?
Mechanical weathering is the breaking down of rocks into smaller pieces without changing the composition of the minerals in the rock. This can be divided into four basic types – abrasion, pressure release, thermal expansion and contraction, and crystal growth.
What are the factors to consider in mechanical weathering?
Many factors contribute to the effect, such as the geometry of cracks, porosity and strength of rocks, rate of cooling, water content in rock pore space, transportation of water to ice formation, etc., are involved that weathering due to ice is exceedingly complicated and a number of hypotheses have been advanced to …
What is the similarities of mechanical and chemical weathering?
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.
What are similarities and differences between physical and chemical weathering?
While physical weathering breaks down a rock’s physical structure, chemical weathering alters a rock’s chemical composition. Physical weathering works with mechanical forces, such as friction and impact, while chemical weathering takes place at the molecular level with the exchange of ions and cations.
