Answer:
- Liquid (molten metals/rocks)
- Silica
- Gasses
Explanation:
The magma is a product of the mantle layer. The temperatures in this layer are very high, and the pressure is also much higher than on the surface. This leads to creating a melt out of the rocks/metals in it, thus creating a thick liquid out of them. Apart from the liquid of molten rocks/metals, a major component of any magma is the silica, which actually determines its behavior ones it reaches the surface of the Earth. The third important component of the magma are the gasses. The gasses are forming bubbles in the magma, and depending on the amount of silica, they can remain trapped and than cause explosions on the surface, or they can escape the magma easily if the magma is not highly viscous.

Hello user!
Here's your answer...
Measurements of unprecedented detail returned by Japan's Hitomi satellite have allowed scientists to track the motion of X-ray-emitting gas at the heart of the Perseus cluster of galaxies for the first time. The results showcase the long-awaited premiere of a next-generation X-ray instrument whose key components were developed at NASA's Goddard Space Flight Center in Greenbelt, Maryland.
Led by the Japan Aerospace Exploration Agency (JAXA), Hitomi was launched on Feb. 17. Following the successful activation of the observatory and instruments, Hitomi suffered a mission-ending spacecraft anomaly on March 26.
Before its demise, though, Hitomi was able to peer into the Perseus cluster of galaxies, an assemblage of thousands of galaxies bound together by gravity. Located about 240 million light-years away and named for its host constellation, the Perseus galaxy cluster contains a vast amount of extremely hot gas. At temperatures averaging 90 million degrees Fahrenheit (50 million degrees Celsius), the gas glows brightly in X-rays. Prior to Hitomi's launch, astronomers lacked the capability to measure the detailed dynamics of this gas, particularly its relationship to bubbles of gas expelled by an active supermassive black hole in the cluster's core galaxy, NGC 1275.
For the first time, thanks to Hitomi's revolutionary Soft X-ray Spectrometer (SXS), an instrument developed and built by Goddard scientists working closely with colleagues from several institutions in the United States, Japan, and the Netherlands, astronomers have mapped the motion of X-ray-emitting gas in a cluster of galaxies and shown it moves at cosmically modest speeds.
That's it.
