"Sediment" Natural Recordings by Native Speakers
Sediment refers to particles or material that settles to the bottom of a liquid or gas in a process called sedimentation. This can include dust, sand, or even tiny particles of organic matter. It can also refer to the resulting mixture of individual particles or aggregates that settle to the bottom of a liquid.
In a broader sense, sediment can also refer to:
Residue or deposit that settles on a surface or at the bottom of something
Material that has been deposited or left behind by a process, such as erosion or weathering
A layer or deposit of rock particles or minerals that has been formed through geological processes
In a figurative sense, sediment can also refer to:
A harmful or disturbing memory or experience that stays in one's mind
A feeling or emotion that builds up and settles inside someone, often making them feel heavy or weighed down.
Sedevacantism is a theological doctrine that emerged in the Catholic Church, particularly in the Western and Southern United States, in the 20th century. The term "sedevacantism" comes from the Latin words "sedere," meaning "to sit," and "vacare," meaning "to be empty." This refers to the view that the papal throne has been vacated, or left unoccupied, since the death of Pope Pius XII in 1958.<br><br>Sedevacantists are primarily traditionalist Catholics who reject the legitimacy of the popes who have successively passed since the Second Vatican Council (Vatican II), arguing that they have compromised Catholic doctrine and introduced heretical innovations. They contend that the betrayals and apostasies of the modern papacy have rendered it impossible for anyone to be the true Pope, leaving the papal throne without a legitimate occupant.<br><br>The major arguments for sedevacantism are grounded in Catholic theology and tradition. Proponents base their rejection of the post-Vatican II popes on several key points:<br><br>1. <strong>Loss of Audacity (Virtus Dicendi):</strong> Sedevacantists argue that a true Pope cannot deviate from Catholic doctrine. They point out that the post-Vatican II popes have made statements and taken actions that contradict established Catholic dogma, thus losing the audacity that is essential for a true Pope to knowingly offend against the faith.<br><br>2. <strong>Defection to Modernism:</strong> Sedevacantists are particularly disturbed by the influence of Modernism, or "Americanism," within the Church. They contend that the embrace of democratic and liberal values over divine revelation renders the papacy invalid.<br><br>3. <strong>Itinerary of the Second Vatican Council:</strong> Many see the Vatican II council as an affront to Catholic tradition. Sedevacantists reject much of its reform agenda, especially the relaxed approach to communion for separated churches and the changed tone on ecumenism.<br><br>4. <strong>Complete Correctio of De Fide Catholica:</strong> Sedevacantists believe that a heretic cannot become the Pope, citing the perennial teaching that a "heretic cannot be a legitimate Pope." Since they identify the successive popes since Vatican II as heretics or problematic for some other reason, they consider the papacy to be vacant.<br><br>The core argument, however, is based on the belief that the official church has completely abandoned the defining characteristics of Catholicism.
Sediba refers to a genus of early human ancestor that lived in Africa between 1.78 and 1.78 million years ago. The name "Sediba" is derived from the Sesotho word "sediba," which means "winding river" and is a reference to the hometown of the discovery site in South Africa.<br><br>Sediba fossils were discovered in 2008 at the Malapa site in the Cradle of Humankind UNESCO World Heritage Site in South Africa. The discovery was significant because the fossils found provided a novel insight into human evolution. <br><br>The most notable Sediba fossils are those of a 1.9 million-year-old juvenile found with an incomplete cranium, as well as an early adult who is usually referred to as "Alice." The adult showing a mix of primitive and more modern features, alongside the possession of a small brain and robust dentition, sparked a significant debate in the scientific community regarding what the Sediba could represent in our human lineage.<br><br>Comparing the set of features the Sediba presents to more earlier fossils, the Sediba appears to be a mashup of a younger, as-yet-unnamed Australopithecus and an adult Savanna chimpanzee from 4 million years ago, known as Paranthropus robustus.
Sedilia (singular: sedile) refers to a stone bench or a fixed seat, usually three or more parallel ones, for priests, officials, or dignitaries, typically found in a large Catholic church, particularly in the chancel or apse.<br><br>In a church, the sedilia is usually positioned near the altar or the sanctuary, but on the side away from the main altar. It allows the priests, deacons, or other officials to sit and rest during long ceremonies or while waiting to perform their duties.<br><br>Historically, the sedilia was an important architectural feature in medieval European churches, particularly in Gothic and Romanesque styles.
Sedimenting refers to the process by which particles, such as sand, silt, or other small particles, settle to the bottom of a liquid or gas, often due to gravity. This can occur naturally, such as in the settling of sediment in a river or ocean, or artificially, such as in the process of filtering or purifying a liquid. Sedimenting can also refer to the act of allowing or causing particles to settle in a specific location.
Sedimentologists are scientists who study the origin, nature, distribution, and composition of sediments on the Earth's surface and in the ocean. They investigate the processes that shape the Earth's surface, such as erosion, weathering, and deposition, and analyze the sediments to learn about the geological history of an area.<br><br>Sedimentologists use a range of techniques, including fieldwork, laboratory analysis, and remote sensing to study sediments. They can work in a variety of settings, including academic research institutions, government agencies, and private companies involved in oil and gas exploration.<br><br>The main areas of study in sedimentology include:<br><br>1. Sedimentary basins: These are areas where sediments accumulate over time, such as deltas, sea floors, and lake beds.<br>2. Sediment transport: This involves studying how sediments are moved from one location to another, such as through rivers, glaciers, or ocean currents.<br>3. Sediment deposition: This is the process of sediments settling and accumulating in a new location, such as a beach or a river delta.<br>4. Sedimentary rocks: These are rocks that are formed from compressed and cemented sediments, such as sandstone, shale, and limestone.<br><br>Some of the key concepts that sedimentologists study include:<br><br>1. Lithification: This is the process of changing sediments into sedimentary rocks.<br>2. Sedimentary facies: This refers to the characteristics of sedimentary deposits in different environments.<br>3. Stratigraphy: This is the study of the layering of rocks and sediments to understand the geological history of an area.<br><br>By studying sediments and sedimentology, scientists can learn about the Earth's history, including past climates, sea levels, and landforms, which can help us better understand the natural world and its changes over time.
Sedimentology is the geology of sedimentary rocks and aquatic sediments. It is the study of sediments, the sediments' properties, and the processes that create and modify sediments, including sediment transport, deposition, lithification, metamorphism, and diagenesis.<br><br>Sedimentologists seek to reconstruct ancient environments, such as ancient oceans, rivers, lakes, deserts, and ice sheets, and to understand the processes that shape the Earth's surface.
