A rapid change in density with depth in the ocean is called a thermocline.
A rapid change in ocean density with depth is called a thermocline. This thermocline is caused by variations in temperature and can impact ocean circulation and marine life distribution.
An example of a rapid change in conditions on Earth is the melting of polar ice caps due to climate change. This melting leads to rising sea levels, changes in ocean currents, and disruptions in ecosystems. These changes have far-reaching impacts on weather patterns, biodiversity, and human populations.
A rapid change in temperature within a specific zone is referred to as a thermal shock. This occurs when there is a sudden and extreme temperature variation in a material or object, leading to stress and potential damage. Thermal shock can cause cracking or distortion in materials.
A volcano is a rapid change because it can go from a state of dormancy to eruption very quickly, often with little warning. The eruption itself can cause immediate and widespread changes to the surrounding environment, affecting landscapes, ecosystems, and communities in a short period of time.
A model of evolution showing slow change is gradualism. It proposes that evolution occurs slowly and steadily over time, with species gradually diverging from common ancestors through small, incremental changes. This contrasts with punctuated equilibrium, which suggests that evolution occurs in relatively rapid bursts of change separated by long periods of stability.
Punctuated equilibrium is the model of evolution in which periods of rapid change occur interspersed with long periods of stability. This theory suggests that species evolve quickly in short bursts of rapid change followed by extended periods of little or no change.
The gradualism model of evolution proposes that species evolve slowly and steadily over long periods of time, with small changes accumulating to result in significant transformations. This contrasts with the punctuated equilibrium model, which suggests that evolution occurs in short bursts of rapid change followed by long periods of stability.
Punctuated Equilibrium, I believe is the answer.
Модель прерывистого равновесия исходит из перехода медленно накапливаемых количественных изменений в качественные с резким эволюционным скачком. Например, одна из хромосом, постепенно утрачивая необходимые для поддержания жизнеспособности признаки, в какой то момент становится необязательной или даже не нужной. Таким образом утратившие её особи-мутанты могут стать родоначальниками нового вида. Или, постепенно повышая холодостойкость, яровой злак может однажды стать родоначальником озимого сорта или вида.
The gradualism model of evolution suggests that evolution occurs slowly and continuously over long periods of time through accumulation of small, incremental changes. In contrast, the punctuated equilibrium model proposes that evolution occurs in rapid bursts of change followed by long periods of stasis, with new species appearing suddenly in the fossil record.
The punctuated equilibrium model of evolution suggests that evolution occurs in rapid bursts of change separated by long periods of stability. This model emphasizes the idea that species evolve quickly in response to environmental changes, leading to abrupt shifts in their characteristics over relatively short periods of time.
One theory is the punctuated equilibrium model, which suggests that evolution occurs in rapid bursts of change followed by long periods of stability. Another theory is the gradualism model, which proposes that evolution happens at a slow and steady pace over long periods of time.
The model for the slow ongoing process of evolution is called gradualism. It suggests that evolutionary change occurs gradually over long periods of time through the accumulation of small, incremental changes in populations. This contrasts with punctuated equilibrium, which suggests that evolution occurs in short bursts of rapid change followed by long periods of stability.
Equilibria
This pattern fits the model of punctuated equilibrium in evolution. It suggests that species experience periods of little to no change followed by rapid bursts of evolutionary change that result in new species formation. This is in contrast to gradualism, which posits a slow and constant rate of evolution over time.
