1. Cool, falling air is associated with __________ pressure areas.
ehidna [41]

Answer:

Cool air falls, this is associated with greater pressures areas.

Warm air rises, this is associated with low-pressure areas.

<u>Explanation:</u>

Due to the <em>differences in air pressure</em>, <em>the wind is blown from 'one location to another location'</em>. The cool air is denser than warm air hence the cool air fells which has high density. The warm air has less density and it rises. So the cool air is related to greater pressure areas and warm air is related to lower pressure areas.

Other than bacteria, which factor leads to nitrogen fixation? A. Lightning B. Flood C. Rain
max2010maxim [7]

Answer:

A. Lightning

Explanation:

Nitrogen is very fundamental for a wide range of life activities in both plant and animals.

Lightning which accompanies thunder during rain storm and other weather phenomenon aids the release of atmospheric nitrogen for life processes. The energy that accompanies a lightning event is mostly electrical in nature. This electrical energy is huge and very massive. As the lightning interacts with free nitrogen molecules in the atmosphere, the molecule is broken down. The free nitrogen which results then combines with oxygen in the atmossphere to form oxides of nitrogen. When oxides of non-metals dissolves in rain water, they make the water rich in nitric acid and can be brought to the biosphere for use by plant and animals.
