What kind of fossil aging is used when scientists use the law of superposition?

When scientists use the law of superposition to determine the age of a fossil, they go by the principle of 'every undisturbed layer of rock is older than the layer above it. This is not the most precise way of determining age, and in fact this method can only reveal the approximate age, but not the exact one.

<u>Answer:</u>

When scientists use the law of superposition, the type of fossil aging they use is known as relative aging.

<u>Explanation:</u>

  • Scientists use different methods of aging to determine the 'age of rock fossils'. One of these techniques is that of relative aging.
  • In this technique, the scientists 'determine the age of the bottom-most rock fossil' first and go by the principle that every new layer of rock superpositioned above the lower rock is comparatively younger than the lower rock.

¿que son los glaciares y en que se diferencian y se parecen a otras formas en las que solemos ver el agua como lluvia y nieve,o
Usimov [2.4K]

Answer:

Comprobar explicación

Check Explanation

Explanation:

Los glaciares se conocen como grandes masas de hielo en movimiento formadas por la caída de nieve. Se mueven continuamente bajo sus propias masas. Se forman cuando la nieve permanece en un lugar en horas extras a bajas temperaturas para transformarse adecuadamente en hielo. Se encuentran fácilmente en la superficie de la Tierra, debido a una acumulación de nieve, que con el tiempo los hace compactos y recristalizados en la nieve. Actualmente, los glaciares ocupan alrededor del 10 por ciento de la superficie terrestre total del mundo, y la mayoría se encuentra en regiones polares como la Antártida, Groenlandia y el Ártico canadiense.

La similitud entre los glaciares y otras formas de agua, lluvia y nieve, es que todas son formas de agua que contienen agua en varias formas. Los glaciares tienen agua en forma sólida (hielo), la lluvia tiene agua en forma líquida y la nieve tiene un poco de ambos.

Los glaciares, al igual que el agua en los cuerpos de agua (océanos, mares, ríos) también tienen su propia forma de agua en movimiento.

La principal diferencia entre los glaciares y otras formas en que existe agua, lluvia y nieve, es el tipo de forma de agua que contienen. Además, en esos casos, la lluvia y el agua son más temporales y desaparecen después de un tiempo de existencia en sus formas iniciales; no se ven en grandes cantidades en su forma inicial pura durante un período de tiempo. Los glaciares permanecen durante un período de tiempo, cubriendo una gran parte de la superficie de la tierra (alrededor del 10%, cubriendo masas de tierra, cimas de montañas, etc.) y se mueven continuamente.

Y para los cuerpos de agua (océanos, mares, ríos), contienen agua en forma líquida. A diferencia del glaciar que es sólidamente agua en forma sólida; hielo.

English Translation

What are glaciers and how are they different and similar to other ways in which we usually see water as rain and snow, or as part of rivers, seas or lakes?

Solution

Glaciers are known as moving, large masses of ice formed from falling snow. They continuously move under their own masses. They are formed when snow remains in one location overtime at low temperatures to transform properly into ice.

They are readily found on the Earth's surface, due to an accumulation of snow, which over time make them compact and recrystallized from snow. Presently, glaciers occupy about 10 percent of the world's total land area, with most located in polar regions like Antarctica, Greenland, and the Canadian Arctic.

The similarity between glaciers and other forms of water, rain and snow, is that they are all water forms containing water in various forms. Glaciers have water in solid form (ice), rain has water in liquid form and snow has a bit of both.

Glaciers, just like water in waterbodies (oceans, seas, rivers) has its own water form always moving too.

The major difference between glaciers and other ways in which water exists, rain and snow, is the type of water form they contain.

Also, in those cases, rain and water are more temporary, disappearing after a while of existence in their initial forms; they are not seen in great quantities in their pure initial form over a period of time. Glaciers remain over a period of time, covering a large part of the earth's surface (about 10%, covering land masses, mountain tops etc.) and are continuously moving.

And for waterbodies (oceans, seas, rivers), they contain water in liquid form. Unlike glacier which is solidly water in solid form; ice.

Hope this helps!!!
