What acts on a rock to change its shape or volume?
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.
What is the force that acts on rock to change its shape?
The force that acts on rock to change its shape is typically stress, which can come from tectonic forces, such as compression, tension, or shear. These stresses can cause the rock to deform, leading to changes in its shape and structure over time.
Describe two types of stress that deform rocks?
Compression (that acts to decrease an objects volume by squashing it together), Tension (which acts to increase an objects volume by pulling it apart) and a bonus Shear which acts in opposite directions on opposite sides of an object to make the two halves slide past each other.
What is external forcing?
External forcing refers to any factor outside a system that influences its behavior or evolution. In the context of climate science, external forcing typically refers to natural or human-induced factors that alter the Earth's energy balance, leading to changes in climate. These can include greenhouse gas emissions, volcanic eruptions, solar radiation, and variations in the Earth's orbit.
What is the cycle for ice wedging?
In the cycle of ice wedging, water seeps into cracks in rocks during the day. At night, the water freezes and expands, causing the crack to widen. As this process repeats, the cracks gradually enlarge, eventually leading to the fragmentation of the rock.
How does momentum change in the system?
Momentum in a system can change if an external force acts on it, causing it to accelerate or decelerate. In a closed system with no external forces, momentum is conserved and does not change.
Is rocks tumbling down a mountain a contact or contact force?
Rocks tumbling down a mountain involve contact forces. As the rocks move, they come into contact with the surface of the mountain and other rocks, creating friction and impact forces. Additionally, gravity acts as a non-contact force that pulls the rocks downward, but the interaction during their descent is primarily characterized by contact forces.
Why semiconductor acts as an insulator at 0K?
Because at this temperature the covalent bond become stronger which can't be broken by applying external forces(voltage).
What are the 2 forces involved in a stretched spring?
The two forces involved in a stretched spring are the restoring force, which acts to bring the spring back to its equilibrium position, and the applied force, which is the external force that stretches the spring.
What are examples of Objects that are distorted by external forces?
ANY object on which an external force acts will be distorted. The distortion MAY be too small to be obvious. An example would be any object resting on some surface - the force being the force of gravity.
What are external traits?
Internal Traits is how a person acts on the inside so... External traits is how a persona acts on the outside
What happeneds to an object at rest if no other forces acts on it?
An object at rest will remain at rest due to Newton's First Law of Motion, which states that an object in motion stays in motion unless acted upon by an external force. Without any external forces acting on it, the object will continue to stay stationary.
Does a gas balloon accelerate?
When a balloon ascends, it undergoes acceleration. This is in spite of the forces like gravity that acts on it. The acceleration of the balloon can be calculated using Newton's second law of physics.
What is a moving force that acts on a structure called?
A moving force that acts on a structure is typically referred to as a dynamic load. This could include forces caused by wind, seismic activity, machinery, or other external factors that can impact the stability and behavior of the structure.
Which radioisotope acts as an external source of ionizing radiation in the treatment of cancer?
Cobalt-60 is the radioisotope that acts as an external source of ionizing radiation in the treatment of cancer.
Why intrinsic semiconductor acts as an insulator at 0K?
room temperature instrinsic s.c as a conducter
If a body is rotating is it necessarily being acted upon by an external torque?
No, a rotating body can maintain its rotation without an external torque if it has an initial angular momentum or is in space with no external forces. However, if the body experiences a change in its rotation speed or direction, then an external torque is likely acting upon it.
