Any time stress causes rocks to change, deformation occurs.
D. Deformation
When stress causes rocks to change, it can result in the deformation of the rock, leading to the formation of faults, folds, or other structural features. Over time, this stress can cause rocks to break and slide past each other, creating earthquakes. Additionally, stress can cause rocks to undergo metamorphism, where they are transformed into new types of rocks under high pressure and temperature.
Any time stress causes rocks to change, deformation occurs.
The force that acts on rock to change its shape or volume is called stress. Stress can be caused by factors such as tectonic plate movement, pressure from surrounding rocks, or even human activities like mining. This stress can lead to the deformation or fracturing of rocks over time.
Tensional stress causes rocks to pull apart. This type of stress occurs when rocks are being pulled in opposite directions, leading to the stretching and extension of the rock mass. Over time, this can lead to the formation of faults and fractures in the rocks.
Pressure causes mechanical weathering by exerting force on rocks, leading to stress and cracks in the rock structure. Over time, the pressure causes the rocks to break down into smaller pieces. This process is known as stress release weathering.
Forces such as compression, tension, and shear can act on a rock to change its shape or volume. Compression squeezes rocks together, tension stretches rocks apart, and shear causes rocks to slide past each other. Additionally, weathering and erosion processes can break down rocks and reshape them over time.
Chemical weathering causes the mineral composition of a rock to change. This process involves the breakdown of minerals in the rock due to chemical reactions with water, oxygen, or acids in the environment. Over time, these reactions can alter the original minerals into different ones.
The force that causes rock to change shape is typically pressure due to tectonic forces, which push, pull, or squeeze the rock. This force can deform the rock, leading to changes in its shape over time. Additionally, factors like temperature variations and erosion can also contribute to the changing shape of rocks.
mechanical weathering
Change is stressful, and most humans like to avoid what causes them stress (opting instead for as much comfort as they think they can get away with).
weathering from mechanical and chemical means the process is causing the rocks to become smaller and smaller each time :)
