Just like most other stars, the sun is made up mostly of hydrogen, followed by helium. Nearly all the remaining matter consists of seven other elements — oxygen, carbon, neon, nitrogen, magnesium, iron and silicon. For every 1 million atoms of hydrogen in the sun, there are 98,000 of...
Hydrogen is the most abundant element in the universe. It’s essential for life: the sun is mostly made of it. And it’s present in almost all living things. But on Earth, pure hydrogen is very scarce. Instead, it mainly exists combined with oxygen in the form of water. So how does...
2.根据第三段内容可知,“ Jupiter's atmosphere is special because it is the solar system's largest atmosphere. It is mostly made up of hydrogen(氢气) and helium(氦气). ”木星的大气层很特别,因为它是太阳系中最大的大气层。它主要是由氢(氢气)和氦(氦气)。故填Because it's made mainly of gas...
Titan, Saturn’s largest moon, is unique in that it has a thick, dense atmosphere made mostly of nitrogen with traces of methane. The pressure on Titan’s surface is about 60% greater than Earth’s – comparable to the pressure beneath 50 feet (15 meters) of water on Earth. 25. The ...
Jupiter's atmosphere resembles that of the sun, made up mostly of hydrogen and helium. A helium-rich layer of fluid metallic hydrogen envelops a “fuzzy” orpartially-dissolved coreat the center of the planet. The colorful light and dark bands that surround Jupiter are created by strong east...
The fifthplanetfrom theSun, Jupiter is the largest planet in thesolar system. It has about 318 times the mass ofEarth, and around 1320 times the volume. Jupiter is made mostly of hydrogen and helium, similar to the Sun, and is known as agas giant. ...
O Our solar system formed from a large cloud consisting mostly of hydrogen and helium and of small amounts of other elements. O Our solar system formed from gases and heavier elements thrown off by the Sun as it rotated in the center of the nebular cloud. O The primordial matter that ev...
So the main gas is hydrogen, which accounts for 90% of the sun’s matter. Now, 'matter'means what something is made of. Rob And hydrogen creates all the sun’s energy. Heat and light energy is created all the time inthe sun’s core as a result...
The surface of the sun is electrically active and it is completely covered by the photosphere. The sun's surface rotates uniformly every 27.3 days unlike the plasma layer of the photosphere.
The Sun is a plasma diffuser that selectively moves light elements like H and He and the lighter isotopes of each element to its surface. The Sun formed on the collapsed core of a supernova (SN) and is composed mostly of elements made near the SN core (Fe, O, Ni, Si, and S), ...
