Which of the following terms refers to the process of mountain building?
Orogeny is the process of mountain building, and may be studied as a tectonic structural event, as a geographical event and a chronological event, in that orogenic events cause distinctive structural phenomena and related tectonic activity, affect certain regions of rocks and crust and happen within a time frame.
What is not a major factor that influences the strength of a rock?
The right answer is high temperature and high confining pressure. Three important parameters must be considered when applying stress-strain concepts to materials of the Earth’s crust: temperature, pressure and time.
Do mountains remain at the same height over long periods of geologic time?
are randomly distributed over the Earth’s surface. B. have roots of continental crust that extend deeper than the level of crust under plains. Mountains do not get infinitely high or exist forever because. their composition (continental crust) causes them to remain buoyant.
Which conditions can cause folding?
Folds form under varied conditions of stress, pore pressure, and temperature gradient, as evidenced by their presence in soft sediments, the full spectrum of metamorphic rocks, and even as primary flow structures in some igneous rocks.
What are the 4 types of mountains?
There are 4 types of mountains, viz. fold mountains, block mountains and volcanic mountains.
What are the 5 types of mountains?
There are five main types of mountains: volcanic, fold, plateau, fault-block and dome.
What are the 4 factors that affect rock strength?
The principal factors controlling the strength of solid rocks are: I) mineral composition, structure and texture; 2) bedding, jointing and anisotropy; 3) water content; 4 ) state of stress in the rock mass.
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 three components of deformation?
The total amount of deformation between two converging bodies is described by the three components of the displacement field: translation, rotation, and strain.
What controls the height of mountains?
Three main processes control mountain height: lateral support of mountains from tectonic forces, which stops mountains from collapsing under their own weight or pushes them up against gravity; climate- controlled erosion; and isostasy, which keeps mountains afloat on the hot and soft mantle material.
What are the four processes in mountain buildings?
Folding, faulting, volcanic activity, igneous intrusion and metamorphism are all parts of the orogenic process of mountain building.
What are the stages of mountain building?
Evolution of Mountains This model suggests that mountain building involves three stages: (1) accumulation of sediments, (2) an orogenic period of rock deformation and crustal uplift, and (3) a period of crustal uplift caused by isostatic rebound and block-faulting.
What is fold and its types?
Types of Folds. Anticline: linear, strata normally dip away from axial center, oldest strata in center. Syncline: linear, strata normally dip toward axial center, youngest strata in center. Antiform: linear, strata dip away from axial center, age unknown, or inverted.
What is difference between folding and faulting?
The difference between folding and faulting is that folding is the pressure of converging plates causing the crust to fold and buckle, resulting in the creation of mountains and hills and faulting is where cracks in the earth’s rock are created because of different movement of tectonic plates.
What is a symmetrical fold?
A symmetrical fold is one in which the axial plane is vertical. An asymmetrical fold is one in which the axial plane is inclined.
