Your answer will be 4, our magnetic field.
Earth itself is largely protected from the solar wind by its magnetic field. However, some of the charged particles are trapped in the Van Allen radiation belt.
Hope this helps, have a great day! :)
There is a device called a thermometer for that...
<span>Carbonic acid formation
CO2(g) + H2O(l) ----> H2CO3(aq)
Dissolving of calcite
CaCO3(s) + H2CO3(aq) ----> Ca(HCO3)2(aq</span>
From smallest to largest it would be individual, population, community, ecosystem, biome, and then biosphere.
