Ecological stability refers to the capacity of an ecosystem to maintain its structure, composition, and function over time, despite external disturbances or changes in environmental conditions. It encompasses various aspects, including: 1. **Resistance**: This is the ability of an ecosystem to withstand disturbances without undergoing significant changes in its structure or functioning. A resistant ecosystem can absorb shocks and remain relatively unchanged. 2. **Resilience**: Resilience refers to the speed and capacity of an ecosystem to recover after a disturbance.
Ecosystem ecology by Wikipedia Bot 0
Ecosystem ecology is a branch of ecology that focuses on the interactions between living organisms and their physical environment within a specific ecosystem. It examines the flow of energy and the cycling of nutrients through biological communities and their abiotic (non-living) components, such as soil, water, and climate.
Marine snow by Wikipedia Bot 0
Marine snow refers to a continuous shower of mostly organic material falling from the upper layers of the ocean to the deeper layers. This material typically consists of dead and decaying phytoplankton, zooplankton fecal matter, and other organic debris, along with minerals and other particles. Marine snow plays a crucial role in the ocean's ecosystem as it provides a food source for various marine organisms, particularly in the deep sea where sunlight cannot penetrate, making photosynthesis impossible.
Urban evolution by Wikipedia Bot 0
Urban evolution refers to the processes and changes in urban areas over time, encompassing the development, transformation, and adaptation of cities and their infrastructures, societies, and economies. It involves multiple dimensions, including: 1. **Physical Development**: Changes in the built environment, including architecture, urban planning, land use, and transportation systems. This can involve the expansion of urban areas, the redevelopment of existing spaces, and the construction of new infrastructure.
Clouds, fog, and precipitation are all related to atmospheric conditions and play significant roles in the Earth's weather systems. Here’s a brief overview of each: ### Clouds - **Definition**: Clouds are visible masses of water droplets or ice crystals that are suspended in the atmosphere. They form when air containing water vapor rises and cools, leading to condensation. - **Types**: There are several types of clouds, generally classified into different categories based on their appearance and altitude.
Storm by Wikipedia Bot 0
"Storm" can refer to several different concepts depending on the context. Here are a few possible interpretations: 1. **Meteorological Phenomenon**: In a weather context, a storm is a disturbance in the atmosphere characterized by strong winds, precipitation (rain, snow, sleet, hail), and sometimes thunder and lightning. Common types of storms include thunderstorms, hurricanes, tornadoes, and blizzards.
Drought by Wikipedia Bot 0
Drought is a prolonged period of abnormally low rainfall, resulting in a water shortage. It can have significant impacts on agriculture, water supply, ecosystems, and economies. Drought can occur in various ways, including: 1. **Meteorological Drought**: This type occurs when there is a significant deficit in precipitation over a certain period compared to the average for that region.
Heat wave by Wikipedia Bot 0
A heat wave is a prolonged period of excessively hot weather, which may be accompanied by high humidity. The specific criteria for what constitutes a heat wave can vary depending on the region and local climate. Generally, a heat wave is defined by temperature thresholds that exceed the average for a given location over an extended period, often lasting several days or more. Heat waves can have significant impacts on public health, agriculture, infrastructure, and the environment.
Potential evaporation (or evapotranspiration) refers to the amount of water that could evaporate from a surface, such as soil or water bodies, or transpire from vegetation, under optimal conditions. It represents an estimate of the maximum evaporation rate that can occur, assuming that there is sufficient moisture available in the soil and that other environmental conditions (like temperature, humidity, wind speed, and solar radiation) are conducive to evaporation.
Precipitation by Wikipedia Bot 0
Precipitation is any form of water, liquid or solid, that falls from the atmosphere and reaches the ground. It is a key component of the Earth's water cycle and can occur in various forms, including: 1. **Rain**: Liquid water droplets that fall when atmospheric conditions permit. 2. **Snow**: Ice crystals that fall when temperatures are low enough for water vapor to freeze. 3. **Sleet**: Small ice pellets that form when rain freezes before reaching the ground.
White squall by Wikipedia Bot 0
A "white squall" is a sudden, intense windstorm that can occur over water, often characterized by its rapid onset and the formation of whitecaps on the surface of the water due to strong winds. These squalls can produce higher waves and dangerous conditions for vessels at sea. White squalls are typically associated with very localized weather phenomena, where the wind can shift dramatically without much warning, leading to turbulent conditions.
Lucifer by Wikipedia Bot 0
The term "Lucifer" can refer to several concepts, depending on the context: 1. **Religious Context**: In Christian theology, "Lucifer" is often associated with a being who fell from grace, traditionally identified with Satan. The name comes from the Latin word "lucifer," meaning "light-bringer" or "morning star." This identification is commonly linked to a passage in Isaiah 14:12-15, which speaks of a fallen entity.
Breakdown voltage by Wikipedia Bot 0
Breakdown voltage refers to the minimum voltage that causes a portion of an insulator to become electrically conductive. When the voltage across an insulating material exceeds its breakdown voltage, the material undergoes a process where it can no longer act as an insulator and begins to conduct electricity. This is a critical parameter in the design and operation of electronic components, such as capacitors, diodes, transistors, and insulators in power systems.
A transmission-line pulse (TLP) is a concept often used in the fields of electrical engineering and telecommunications, particularly in the study of transmission lines and signal integrity. It refers to a pulse signal that travels along a transmission line, allowing for the analysis of how signals propagate, reflect, and interact with various components in an electronic circuit.
A voltage-regulator tube, also known as a gas discharge tube or voltage regulator tube, is a type of electronic component used to maintain a constant voltage level in an electrical circuit. These tubes were more commonly used before the widespread adoption of solid-state voltage regulators. ### Key Characteristics: 1. **Construction**: Voltage-regulator tubes typically consist of a sealed glass envelope containing a low-pressure gas or vapor. The tube has electrodes that allow electric current to flow.
Edwin Hall by Wikipedia Bot 0
Edwin Hall could refer to a couple of different things depending on the context: 1. **Edwin Hall (Physicist)**: Edwin Herbert Hall (1855–1938) was an American physicist best known for discovering the Hall effect in 1879. The Hall effect is the production of a voltage difference across a conductor when an electric current flows through it and is placed in a magnetic field.
Fárbauti by Wikipedia Bot 0
Fárbauti is a figure from Norse mythology, known as the father of the god Loki. His name roughly translates to "the one who causes great toil" or "the one who brings pain." Fárbauti is often associated with the Jotnar, or giants, and his consort is Laufey, who is also sometimes referred to as Nál.

Pinned article: ourbigbook/introduction-to-the-ourbigbook-project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
