What does a rise and fall of pressure occur with?

A rise and fall of pressure typically occurs with changes in weather systems. For example, high pressure systems are associated with clear, calm weather, while low pressure systems are associated with cloudy, stormy conditions. These pressure changes can be felt in our bodies and can also impact our mood and well-being.

What conditions does physical change occur in materials?

Physical changes in materials occur when the material undergoes a change in its physical properties without any change in its chemical composition. Examples of conditions that can cause physical changes include changes in temperature, pressure, or exposure to light or electricity. Physical changes can include changes in state (such as melting or freezing), changes in shape or size, or changes in properties (such as conductivity or solubility).


A force that changes a rocks shape or volume is called?

The force that changes a rock's shape or volume is called stress. This can occur due to factors such as compression, tension, or shear forces acting on the rock.


What does microangiopathic changes mean?

Microangiopathic changes refer to pathological changes that occur in small blood vessels, leading to vessel damage and dysfunction. This can include thickening of vessel walls, narrowing of the vessels, and formation of microthrombi. These changes can impair blood flow to tissues and organs, leading to various complications.

What is decompression waves?

Decompression waves are patterns of increasing pressure that occur when air is rapidly forced out of a confined space, typically during an explosion or rapid depressurization. These waves can cause damage to nearby structures and pose a threat to anyone in the vicinity due to the rapid changes in pressure.


What are some changes that occur when a sedimentary rock changes into a metamorphic rock?

To change a sedimentary rock to a metamorphic rock, you change it by time,heat, and pressure.


What are temperature changes that occur even though heat is not added or subtracted?

Temperature changes may occur due to changes in pressure, volume, or physical state of a substance, known as adiabatic processes. This is governed by the ideal gas law, which relates pressure, volume, and temperature of a gas. Additionally, temperature changes can result from chemical reactions or phase changes within a system.


What is caviation?

Cavitation is the formation of vapour cavities in a liquid, caused by rapid changes in pressure. These cavities collapse with great force, leading to damage in equipment and machinery operating in the liquid. Cavitation can occur in pumps, propellers, and other hydraulic systems.


Where in the world do earthquakes occur and why?

They can happen ANYWHERE and ANY TIME However they tend to be concentrated at the boundaries of tectonic plates as this is where the greatest pressure / stress develops within the earth's lithosphere.


What can occur when CSF accumulates abnormally?

What damage can occur due to hematoma during otoplasty?

In the case of the ear, a hematoma can damage the results of plastic surgery because it creates tension and pressure that distort the final shape of the ear.
