At the center of every atom lies a small, dense "nucleus" that is positively charged.
Atom is the smallest unit of matter. It is made up of electrons, protons and neutrons. Electrons are negatively charged particles that are found scattered in different energy levels outside the nucleus. Protons are positively charged particles present inside the nucleus. Neutrons do not carry charge and found inside the nucleus. Thus, protons and neutrons make up the nucleus of an atom. Since, protons are positively charged and neutrons are uncharged particles, the charge of nucleus becomes positive.
<span>Ocean current that is moving toward the equator is cold. The windblown surface currents distribute heat all over the globe through moving the water which is warm away from the equator and the cool water will replace which is from the north and south poles. An example of this is the Gulf Stream which moves warm water towards the Great Britain and Europe.</span>

<em><u>Weathering</u></em></h2>
Explanation:
<h3><em>Weathering is a term which describes the general process by which rocks are broken down at the Earth's surface into such things as sediments, clays, soils and substances that are dissolved in water. </em></h3>
<u><em>As weathered products are carried away, fresh rocks are exposed to further </em><em>we</em><em>athering</em><em>.</em></u>
