Answer:
With the heavy inner core, the earth's orbit and rotation will remain stable over the long term, giving us day and night and summer and winter. ... These swirling convection currents result in the earth's magnetic field which keeps us properly oriented for travel, and shields earth from deadly cosmic rays
Explanation:
The inner core is the fourth layer inside the Earth. It is a solid metallic ball made mainly of iron. Here, temperatures reach extraordinary levels, estimated to be between 7,200–8,500ºF (4,000–4,700ºC). Although the inner core is very hot, it is not liquid like the outer core.

The appropriate strategy would be to look for soil bacteria, which transforms nitrates into nitrogen gas.
A microbial mediated procedure where nitrate is reduced and eventually generating molecular nitrogen via an array of intermediate gaseous nitrogen gaseous outcomes is known as denitrification.
It is generally the withdrawal or the loss of nitrogen or nitrogen components, mainly the reduction of nitrites or nitrates by the bacteria in the soil, which usually leads to the escape of nitrogen into the atmosphere.
