Answer:
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.
Answer:B. Intensity
Explanation:
The Intensity of an earth quake refers to the noticeable and severity effects of damage on man made structures, natural(crops and livestock) and human life at different locations. To measure the intensity of an earthquake, the Modified Mercalli Intensity Scale is used and consists of 12 levels of intensity(in roman numerals) that rank the extent of damage based on observable effects with the higher levels based on structural damage.
A Level I -V1 Intensity on the scale will show slight damages to properties and treatable injuries to people, but going higher on the scale above VI shows total damage and destruction to structures and human life.
