Explanation: <em>The hypothesis is a prediction, but it involves more than a guess. Most of the time, the hypothesis begins with a question which is then explored through background research. It is only at this point that researchers begin to develop a testable hypothesis.</em>
(Unless you are creating an exploratory study, your hypothesis should always explain what you expect to happen)
Answer:
Convention currents are found in the asthenosphere part present in the mantle of the Earth.
Explanation:
The Mantle is the middle layer of the earth surface extending up to 2900 kilometers.
Beneath the Mantle lies the core which contains molten rocks and materials called magma.
The materials are highly radioactive and immensely heated. These highly hot condition creates pressure on the middle layer (Mantle).
As a result, large convention currents are generated excessively
Answer:
<em>By</em><em> </em><em>Bayer</em><em> </em><em>process</em><em>.</em>
Explanation:
<em>In the Bayer process, bauxite ore is heated in a pressure vessel along with a sodium hydroxide solution (caustic soda) at a temperature of 150 to 200 °C. At these temperatures, the aluminium is dissolved as sodium aluminate (primarily [Al(OH)4]−) in an extraction process.</em>
