What two things change as rocks undergo stress?
As rocks undergo stress, two things that change are their shape and their volume. The rocks may deform and change their shape based on the type of stress applied, while their volume may also change as the rocks compress or expand under pressure.
What is it called when rocks can bend?
When rocks can bend without breaking, this phenomenon is known as "ductility." Ductile rocks can deform under stress and retain their new shape, typically occurring at high temperatures and pressures deep within the Earth. This characteristic is essential in geological processes like mountain building and the formation of folds in rock layers.
Is basalt malleability or ductility?
Basalt is neither malleable nor ductile; it is a type of igneous rock that is typically characterized by its hardness and brittleness. Malleability refers to the ability of a material to deform under compressive stress, while ductility refers to the ability to deform under tensile stress. Basalt tends to fracture rather than deform plastically, making it unsuitable for applications that require malleability or ductility.
Where is the energy of an earthquake stored before the earthquake?
The energy of an earthquake is stored as elastic strain energy in the Earth's crust along the fault line prior to the earthquake. This energy is released when the stress on the fault exceeds the strength of the rocks, causing them to break and the energy to be radiated as seismic waves.
What fault is it that rocks become twisted and strained when they snag each other?
When rocks become twisted and strained due to snagging, it is due to the tectonic forces acting on them. These forces can cause rocks to deform and bend, resulting in various types of rock formations like folds and faults. The interaction between these rocks under stress can lead to their deformation and eventual displacement along fault lines.

If The higher the temperature the more likely it is that a rock will deform?
Yes, increased temperature can make rocks more likely to deform because it causes minerals within the rock to become softer and more malleable. This allows the rock to bend and flow more easily under stress. However, extreme temperatures can also cause rocks to fracture rather than deform.
Identify two ways that rocks deform?
Rocks deform through brittle deformation, which results in the formation of faults and fractures, and ductile deformation, which involves the bending and flowing of rocks under high temperature and pressure conditions.
The ability of a material to withstand permanent deformation under tensile stress without fracture is?
Ductility is an objects ability to deform under tensile stress.
How is the energy that causes an earthquake stored before the earthquake happens?
Energy is stored in rocks along faults as stress builds up from tectonic plate movements. This stress gradually deforms the rocks until they can no longer hold the energy, leading to a sudden release in the form of an earthquake.
What are the characteristics of strain liquids and how do they differ from other types of liquids?
Strain liquids have a high viscosity, meaning they are thick and flow slowly. They can deform under stress but return to their original shape when the stress is removed. This sets them apart from other liquids, which have lower viscosity and do not deform as easily under stress.
Why do rocks bend then break?
Even brittle solids have some elasticity, this allows for some bending before fracture. However rocks in the ground are complex substances and full of water, this changes their properties as compared to rocks at outcrop. Also you must understand that the forces that deform rocks are applied very slowly. Rock deformation and fracture is a very complex subject.
What happens to rocks after their elastic limits passed?
They will begin to deform plastically. That is the deformation will be permanent. Depending on the pressure and temperature conditions the rock will either continue to deform very slowly and "flow" (this occurs at great depth under high pressure and temperature conditions) or the rock will undergo brittle failure where fractures form - this occurs at shallow depths with low temperatures and low confining pressures.The rock breaks
Why do some rocks bend while other rocks break?
This depends on the confining pressure, the temperature and the strain rate applied to the rock mass. In general, the lower the rate of strain, the more likely ductile or plastic deformation leading to bending or folding will occur. The higher the strain rate, the more likely brittle deformation is to occur, leading to the rock "breaking". As the confining pressure increases, a materials shear strength will increase (this usually coincides with a greater depth of burial) and due to the Earth's thermal gradient an increase in temperature. As the shear strength of the rock increases, the occurrence of brittle failure is less likely while the higher temperature means that plastic deformations are more likely to occur.
What is compression in Earth science?
Compression in Earth science refers to the stress applied to rocks that causes them to deform by being squeezed or shortened. This can occur in response to tectonic forces, such as when two tectonic plates collide or when rocks are buried under a heavy load. Compression can lead to the folding, faulting, or fracturing of rocks.
