Somalia is located on the Horn of Africa, a peninsula on the eastern coast of Africa that separates the Gulf of Aden to the north and the Indian Ocean to the east and south. 
So the answer is: east of ethiopia
        
             
        
        
        
Location is determined by longitude and latitude.
        
             
        
        
        
Answer:
Ferrous (Fe²⁺) and magnesium cation (Mg²⁺).
Explanation:
The olivine mineral is a type of orthosilicate, which is generally yellow to yellow-green in color. It is the main component of the upper mantle of the Earth, which can be found in igneous and metamorphic rocks.
The olivine mineral exists in the form of Mg₂SiO₄, Fe₂SiO₄, or (Mg,Fe)₂SiO₄.
<u>This silicate consists of two divalent cations, ferrous (Fe²⁺) and magnesium cation (Mg²⁺).</u>
 
        
             
        
        
        
Answer:
- 1. <u>     d. hydrolysis  </u>  chemical reaction involving ions in water (OH⁻ and H⁺ )
- 2. <u>    e. oxidation    </u>chemical reaction in which minerals are weakened by oxygen
- 3. <u>    b. abrasion    </u> away or grinding by friction
- 4. <u>     a. weathering    </u>  breakdown and change of rocks and minerals over time
- 5.<u>      c. dissolution     </u> process of dissolving
Explanation:
<u><em>a. Weathering </em></u>is due to the reaction of rocks and minerals with the air, water and organisms, which cause the rocks and minerals to breakdown and change. This, normally, is a slow process that involves chemical and physical changes.
<u><em>b. Abrasion </em></u>is the wear caused by the friction of the materials.
<u><em>c. Dissolution</em></u> is the process of dissolving a solute in a solvent. For instance, salt in water.
<u><em>d. Hydrolisys</em></u> is the chemical reaction of a substance with water, being the ions H⁺ or OH⁻ from water the agents responsible for the reaction.
<u><em>e. Oxidation</em></u> is the chemical reaction of an element with oxygen. In such reactions, the element transform into a compound that, commonly is weaker than the element. For instance, oxygen oxidates iron producing iron oxide (rust) which is weaker than iron.
