The condition of structural failure or disintegration, resulting in the loss of functionality of an object or entity, often associated with buildings or organizational structures.
A phenomenon in which an unstable particle or atomic nucleus undergoes spontaneous division or transformation into a different type, often involving the release of radiation, exemplified by processes such as alpha decay or beta decay.
A state of complete breakdown or deterioration in a system, organization, or society, often leading to chaos or significant dysfunction, such as the fall of a civilization.
The process by which something fails to maintain its integrity or stability, leading to a total loss of its original form or purpose.
Example:
チューダー朝は１６０３年に崩壊した。
A situation or condition that is extremely unstable and close to disintegration or failure.
A state characterized by imminent breakdown or total failure, often due to overwhelming pressure or stress.
The critical moment before a structure, system, or organization is unable to function effectively and may completely fall apart.
An impending crisis where conditions are deteriorating rapidly, suggesting that a significant collapse is about to occur.
A phenomenon occurring when the nuclear fusion reactions in a star's core cease, leading to a loss of internal support, causing the star's material to rapidly fall inward under the influence of gravity, often resulting in the formation of a neutron star or a black hole, and frequently associated with a supernova explosion.
The final evolutionary stage of a star characterized by the intense gravitational forces overwhelming the resistance from nuclear reactions, causing a dramatic inward collapse that can lead to the creation of extremely dense objects such as neutron stars or black holes.
The process where gravity becomes the dominant force in a star after the exhaustion of its nuclear fuel, resulting in a rapid inward fall of stellar material, which may culminate in explosive events or the formation of new astronomical entities.
A situation in which the classroom environment becomes unmanageable, characterized by persistent disruptions and misbehavior by students, rendering effective teaching and learning impossible.
A prolonged state of disorder within a classroom where the teacher is unable to maintain control due to students' constant talking and unruly behavior.
A breakdown in the normal functioning of a class over an extended period, often marked by a failure to enforce discipline, leading to a chaotic atmosphere that hinders educational progress.
The event where a wall collapses due to structural failure or external pressure, resulting in the wall breaking apart and losing its vertical integrity.
A sudden failure of a wall that causes it to break down, often leading to potential hazards or damage in the surrounding area.
The phenomenon in which a wall loses stability and subsequently falls, typically indicating serious issues with construction or environmental factors.
The process or circumstance under which a wall gives way, resulting in the debris from the wall spilling into the space it once enclosed.
