We know, that Convection<span> is the movement of groups of </span>molecules<span> within </span>fluids<span> such as </span>liquids<span> or </span>gases<span>, and within </span>rheids <span> Examples of Global processes occurs by it:
1) Atmospheric Circulation. - It </span><span>is the large-scale movement of air, and is a means by which thermal energy is distributed on the surface of the Earth, together with the much slower (lagged) ocean circulation system. </span> 2) Oceanic Circulation . - <span>Solar radiation affects the oceans: warm water from the Equator tends to circulate toward the </span>poles<span>, while cold polar water heads towards the Equator. </span> 3) Weather. - Most important process if Weather including mineral cycle. Example in Hydrological cycle <span>a </span>foehn wind<span> is a down-slope wind which occurs on the downwind side of a mountain range. It results from the </span>adiabatic<span> warming of air which has dropped most of its moisture on windward slopes.
According to provided equation it is clear that Zn metal is oxidized from Zn⁰ into Zn²⁺ which means that Zn metal dissolves and forming Zn²⁺ solution so the correct answer is:
