What effects does ionizing have on the atmosphere? Select the two correct answers.

The two correct answers are:

1. Ionizing radiation can break chemical bonds in the atmosphere, leading to the formation of ions. These ions can then participate in chemical reactions and contribute to the formation of various atmospheric pollutants.

2. Ionizing radiation can also cause ionization of atoms and molecules in the atmosphere, leading to the creation of free electrons and positive ions. These charged particles can affect atmospheric electrical conductivity and participate in electrical discharge processes such as lightning.
