ablatión

Ablation is a general term used in various scientific and medical fields to describe the removal or destruction of material from the surface of an object by vaporization, chipping, or other erosive processes. In medicine, ablation refers to procedures that remove or destroy abnormal tissue. This can be done for a variety of reasons, such as treating cancerous tumors, correcting arrhythmias in the heart, or removing uterine fibroids. Common methods of medical ablation include radiofrequency ablation, which uses heat generated by radiofrequency energy, and cryoablation, which uses extreme cold. Laser ablation is another technique that employs focused laser beams to remove tissue. The specific method chosen depends on the location, size, and type of tissue to be ablated.

In geology and astronomy, ablation refers to the erosion or wastage of snow, ice, or rock. For example, glacial ablation is the loss of ice from a glacier due to melting, sublimation, or calving of icebergs. On Earth, wind and water can also cause ablation, wearing away rock formations over long periods. In astronomy, ablation occurs when celestial bodies, such as meteors, enter a planet's atmosphere. The friction with the air causes the object to heat up and burn away, a process often referred to as ablation. This can result in a visible streak of light, commonly known as a shooting star. The extent of ablation depends on the object's size, speed, and atmospheric composition.
