In the core of the Sun, hydrogen atoms slam together at high speed and are converted into helium nuclei. As a result, some of the original mass of the hydrogen atoms is lost. What happened to it?

Questions: Answer the following questions involving the Sun
1. The interior and exterior of the Sun have layers that vary in terms of temperature, pressure, and density. Additionally, the processes involved for the transference of energy/light differ amongst them. Below, you see several statements describing different layers. In each of the blanks next to them, put one letter that identifies the name of the layer being described from this list:
A) core,
B) radiative zone,
C) convection zone,
D) photosphere,
E) chromosphere, and
F) corona
This layer is often referred to as the Sun’s visible surface______
This is the region from which most of the emitted x–rays radiate into space______
Energy is transported outward when hot gas rises and cooler gas falls in this layer______
It is in this area of the Sun that nuclear fusion occurs______
This portion of the Sun has energy conveyed through it via photons______
2. In the core of the Sun, hydrogen atoms slam together at high speed and are converted into helium nuclei. As a result, some of the original mass of the hydrogen atoms is lost. What happened to it?
3. In your own words, describe the changes in temperature and density one would hypothetically encounter if they could travel through the Sun’s convection zone and radiative zone, ending up in the core. Be specific in your statements.

4. Starting at the photosphere, then moving through the chromosphere into the corona, describe the changes in temperature and density one would encounter if that hypothetical trip could be traversed. Be specific in your statements.
5. The phrases “solar weather”, “solar storms”, and “solar activity” are used interchangeably to refer to the collection of events that happen in the outer layers of the Sun. Solar flares and coronal mass ejections (CME) are two examples of the events. When these occur, they often have no impact on human activity. However, if the timing is right, and the intensity of these events are great enough, they can affect activity on Earth on both a small and a large scale. Discuss (Don’t just “list”) two ways society can be affected when these events encounter the Earth.
6. RESEARCH: People within the magnetic field of the Earth are protected by the harmful radiation and particles emitted by the Sun’s solar wind and solar storms. In the future, humans will likely attempt to travel outside of this zone of safety to places such as the Moon and Mars. Do some research and report (200 words minimum) on the proposed ways people can be shielded from the harmful effects of the Sun during space travel.
