"Asthenosphere" Natural Recordings by Native Speakers
The asthenosphere is the weak and ductile region of the Earth's mantle beneath the lithosphere, extending from about 100 to 250 kilometers (62 to 155 miles) below the surface. It is the zone where the Earth's mantle flows and deforms over time, driving plate tectonics and the movement of the Earth's surface.
Asterope is a mythological name, derived from Greek mythology. In Greek legend, Asterope or Asteropae was one of the Pleiades, a group of seven sisters who were daughters of Atlas and Pleione. They were often associated with stars, and according to various stories, Asterope was either turned into a star herself or was the inspiration for one of the stars in the Pleiades star cluster.

Asterophyllite is a mineral, a variety of the amphibole group, characterized by its prismatic crystals that often have a star-like pattern when viewed under polarized light. It typically occurs in metamorphic rocks and is named from the Greek words "astron" (star) and "phyllon" (leaf), referring to its distinctive crystal form.
Asteroseismology is a branch of astronomy that focuses on studying the internal structures and dynamics of stars by analyzing their oscillations or seismic vibrations. It involves the observation and interpretation of stellar oscillation modes, which act as "sound waves" traveling through the star's interior. By examining these oscillations, astronomers can gather information about a star's composition, temperature, age, mass, and other fundamental properties.
"Asterozoa" is a term that refers to a group of marine animals within the phylum Echinodermata. These animals are commonly known as starfish or sea stars. They have a star-shaped body plan with arms radiating from a central disk. Asterozoa are characterized by their hard external skeletons, tube feet used for movement and feeding, and a unique water vascular system. They are found in various habitats worldwide, including oceans, reefs, and seagrass beds.
The word "asthavent" is a verb phrase that is derived from "astrive" (to strive or struggle) and "avent" (a rare or obsolete word that means "to come or happen"). The meaning of "asthavent" is approximately equivalent to "have striven" or "have struggled".

Asthenopia, also known as eye strain or visual fatigue, refers to a group of symptoms that occur after prolonged use of the eyes, such as reading, working on a computer, or staring at a screen for extended periods. It typically includes discomfort, pain, or fatigue in the eyes, and may be accompanied by headaches, blurred vision, double vision, or sensitivity to light. Asthenopia is usually not a serious condition but can affect daily activities and productivity. Resting the eyes, following the 20-20-20 rule (looking away from the screen and focusing on an object 20 feet away for 20 seconds every 20 minutes), and proper lighting can help alleviate symptoms. If symptoms persist, it's advisable to consult an optometrist or ophthalmologist.
Astheny is a medical term that refers to a state of weakness or lack of strength, typically affecting muscles or the entire body. It can be a symptom of various conditions, such as fatigue, malnutrition, chronic illness, or neurological disorders.
Asthma is a chronic respiratory condition characterized by inflammation and narrowing of the airways, leading to difficulty in breathing, wheezing, coughing, and shortness of breath. It can be triggered by various factors such as allergens, exercise, cold air, or irritants. Asthma severity varies from person to person and can be managed with medications, inhalers, and avoiding triggers.
Asthma is a chronic respiratory condition characterized by inflammation and narrowing of the airways, leading to episodes of wheezing, shortness of breath, chest tightness, and coughing. It affects people of all ages and can be managed with medication and lifestyle changes. Triggers for asthma attacks may include allergens, exercise, cold air, stress, or respiratory infections.
Asthmatic refers to someone who has asthma, a chronic respiratory condition characterized by difficulty in breathing, wheezing, coughing, and chest tightness, often due to inflammation and narrowing of the airways. People with asthmatic tendencies may experience these symptoms periodically or in response to triggers such as allergens, exercise, or cold air.
"Asthmatically" is an adverb that refers to something related to asthma, a respiratory condition characterized by difficulty in breathing, wheezing, and coughing. If someone performs or experiences something asthmatically, it means they do it in a way that is associated with or affected by asthma. For example, "He spoke asthmatically, struggling to catch his breath after running."
Asthmatics refers to people who have asthma, a chronic respiratory condition characterized by difficulty breathing, wheezing, coughing, and chest tightness. These individuals may experience these symptoms due to inflammation and narrowing of the airways, often triggered by allergens, exercise, cold air, or other irritants. Asthmatics often require the use of inhalers or other medications to manage their symptoms and maintain airflow in their lungs.
