The atmosphere's variable gases that most influence the greenhouse effect are <em><u>carbon dioxide and water</u></em>.
<h3><u>Explanation</u>;</h3>
<em><u>Green house effect is a phenomenon where the radiation from the atmosphere of the earth warms the surface of the earth to a temperature above what it would be.</u></em> It occurs when the atmosphere traps heat radiating from the earth towards the space.
<em><u>Certain gases in the atmosphere block the heat from escaping, these gases are called the green house gases. </u></em>These gases contribute to the green house effect, they include, <em><u>water vapor which is the most abundant green house gas, carbon dioxide a very important component of the atmosphere,</u></em> methane, nitrous oxide, CFCs, etc.
Because the powder has more finer and larger surface area hence it absorbed faster and it becomes more effective in performance compared to the tablet that will still need to be dissolved before it is been assimilated into the body system.
