question 42 options:

co2

n2

ozone

ch4

N₂

Explanation:

The primary greenhouse gases in the atmosphere are carbon dioxide, methane, nitrous oxide, water vapour and ozone. These gases allow sunlight to reach the Earth's surface unhindered. The sunlight heats the surface. The heat as infrared reradiated to the atmosphere, the greenhouse gases absorb the heat energy. They do not allow heat to escape back trapping' the gases in the lower atmosphere.

Nitrogen is an inert gas present in the atmosphere is about 78%.

Only some nitrogen-fixing bacteria such as Rhizobium which fixes atmospheric nitrogen into the soil.

Thus, N₂ (nitrogen) is not a greenhouse gas.
