Which process is defined as breaking down rocks into smaller pieces without changing the rocks compositions Brainly?
Explanation: Mechanical weathering breaks rocks into smaller pieces without changing their composition. Ice wedging and abrasion are two important processes of mechanical weathering.
What is the process of breaking down rocks into smaller pieces called?
Weathering is the physical and chemical breakdown of rock at the earth’s surface. The physical breakdown of rock involves breaking rock down into smaller pieces through mechanical weathering processes. These processes include abrasion, frost wedging, pressure release (unloading), and organic activity.
What are the 2 main types of weathering?
Weathering is often divided into the processes of mechanical weathering and chemical weathering. Biological weathering, in which living or once-living organisms contribute to weathering, can be a part of both processes. Mechanical weathering, also called physical weathering and disaggregation, causes rocks to crumble
What does abrasion do to rocks?
Rocks break down into smaller pieces through weathering. Rocks and sediment grinding against each other wear away surfaces. This type of weathering is called abrasion, and it happens as wind and water rush over rocks. The rocks become smoother as rough and jagged edges break off.
What is an example of abrasion of a rock?
An area of rocks on a shoreline that has been worn away from the waves is an example of an abrasion. The process of wearing down or rubbing away by means of friction. A rock undergoes abrasion when particles of sand or small pieces of rock are carried across its surface by a glacier, stream, or the wind.
What causes rocks to bend and fold?
When rocks deform in a ductile manner, instead of fracturing to form faults or joints, they may bend or fold, and the resulting structures are called folds. Folds result from compressional stresses or shear stresses acting over considerable time
What is the angle of fault plane with the horizontal called?
Explanation: The dip of the fault is its inclination with the horizontal as measured in a vertical plane at right angles to the strike of the fault.
Which type of fault is most dangerous?
Short-circuited fault is one of the most dangerous and common faults occurring in power system, which includes three-phase short circuit, two-phase short circuit, two-phase grounding short circuit and single-phase grounding short circuit.
