Answer:

Fusion

Explanation:

Supernova Definition:

The supernova occurs after fusion begins to pile up iron in the high-mass star's core. Because iron fusion cannot release energy, the core cannot hold off the crush of gravity for long. In the instant that gravity overcomes degeneracy pressure, the core collapses and the star explodes.

Fun Fact!

Approximately one supernova occurs every second. Supernova happens more often than you might think: One occurs somewhere in the universe every second!

Setler79 [48]

Answer:

Listed

Explanation:

The three major air pollutants are Carbon monoxide(CO), Particulate Matter(PM10, and PM2.5) and Ozone(O3).

1.Carbon monoxide is colorless, odourless gas, mainly produced due to incomplete combustion of fossil fuels. CO has a great affinity for blood oxygen carrier, haemoglobin, forming carboxyhemoglobin. This substance is very harmful for humans. It can cause headache, dizziness, weakness, neusea, vomiting, and finally loss of consciousness.

2. Particulate matter(PM) are particles of certain size which when enter our body can cause a lot of damage. PMs are linked with pulmonary and cardiac disease. It initiates a lot of lungs and heart diseases. Depending upon the level of exposure PMs can also cause premature deaths.

3.Ozone is an allotrope of oxygen generally found in upper atmosphere in the stratosphere, protects us from harmful ultra violet rays of the sun. The ground level ozone (GLO) are harmful to human health. Ozone can cause risk of respiratory disease like Asthma.
