WebOct 18, 2024 · The Sun is composed of seven layers: three inner positions and four outer layers. Snap for even more facts & download to worksheets collection. WebAround the core lie two layers: a thick layer called the radiative zone and a thinner, cooler layer called the convective zone. Surrounding all of them is the sun’s surface layer, known as the photosphere. Above this lies the sun’s thin atmosphere, which is made up of the chromosphere and the corona. Most of the sun is made up of hydrogen ...

It reaches from the surface visible … WebThey appear as dark "hairs" above the solar surface. In solar physics, a spicule, also known as a fibril or mottle, [a] is a dynamic jet of plasma in the Sun 's chromosphere about 300 km in diameter. [1] They move upwards with speeds between 15 and 110 km/s from the photosphere and last a few minutes each. [1]

WebSep 23, 2024 · The Sun contains about 92% hydrogen and 8% helium, with just a tiny bit of the other common elements we find on Earth. Compare that to Earth, where the most common elements are oxygen, magnesium, silicon, and iron. On Earth, hydrogen barely makes the top 10 list of common elements, and helium is extremely rare.
