Answer:
Iron cannot release energy either by fission or fusion.
Explanation:
When a high-mass star runs out of hydrogen inside its core, it starts burning helium, and then heavier elements until it reaches iron.
Nuclear fusion of iron cannot occur, because the amount of energy required for the fusion of two nuclei of iron is larger than the energy released.
Therefore, when all the lighter elements lighter than iron have already fuse together, the star cannot burn any other element, so the nuclear fusion inside the core stops and the star collapses on itself, producing a huge explosion known as supernova.
The answer is Greenhouse gases
Greenhouse gases absorbs and emit radiation within thermal infrared range . This process create a condition which commonly known as the greenhouse effects, keeping the earth at a moderate temperature.
Answer:
These lines are called lines of longitudes.
Explanation:
There is a difference between longitudes and lines of longitudes.
- Longitude: It is the angular distance from one point location to another point location on the globe.This angular distance is measured with the help of lines of longitudes.
- Lines of longitudes: These are imaginary lines that run around the Earth vertically (up and down) and meet at the North and South Poles. These lines are also termed as meridians. The Prime Meridian is located at 0° and the lines of longitude run east and west of Prime Meridian. There are 360 longitudes in total (180 east and 180 west of Prime Meridian). Further, all longitudes are also great circles.
