"Vulcanologists" Natural Recordings by Native Speakers
A scientist who studies volcanoes and their eruptions.
Vulcanized rubber refers to rubber that has undergone a process of vulcanization, a chemical reaction that involves the addition of sulfur or other cross-linking agents to the rubber molecules. This process increases the strength, durability, and resistance to heat and chemicals of the rubber, making it more suitable for various applications.<br><br>In a broader sense, vulcanized can also refer to something that has been "set in stone" or made more durable, similar to the idea of setting concrete.
To change rubber or other substances into a more durable form by adding sulfur and heating them together under pressure.
The term "vulcanized" refers to the process of treating rubber or other materials with sulfur or sulfur compounds, typically under heat and pressure, to create a strong, elastic and flexible material that retains its shape but can still stretch, such as in the manufacture of tires, belts and hoses. The process is named after the Roman god of fire Volcanus/Vulcan, because it was discovered by Charles Goodyear in 1839.
The process of treating rubber compounds with sulfur, to improve their strength, durability, and resistance to wear and tear, usually by heating them in a press until a chemical change occurs.
A volcanic landform that occurs when magma from the Earth's interior rises to the surface, resulting in eruptions of molten rock, ash, and gas.
Vulcanology is the scientific study of volcanoes, including their structure, behavior, and relationship to the Earth's surface and interior. It involves the study of the birth, growth, and life-cycles of volcanoes, as well as the physical and chemical processes that occur within them, and the landforms that are created by volcanic activity.
The word "vulgar" can have two meanings:<br><br>1. Lacking in refinement, taste, or breeding: describing something or someone as uncultivated, coarse, or unrefined.<br>Example: "He made a vulgar comment at the dinner table."<br><br>2. Common or ordinary: not special or remarkable.<br>Example: "Their house on the street is suitable, but not very vulgar.
To make something seem less refined or sophisticated in culture, behavior, or language; to make something seem common or crude.<br><br>Example: "The company's decision to prioritize profits over people was seen as a vulgarisation of their values."
Being made to seem unpleasantly or unacceptably common or unrefined by being made widely known or understood.<br><br>Example: The media coverage of the scandal vulgarised the personal details of the politician.
