The countries of the Arabian peninsula solve the problem of obtaining the scarcest resource by building industrial plants to remove the salt from seawater to use it for irrigation and drinking.
Answer: Option A
<u>Explanation:</u>
- Water is the scarcest resource of the Arabian peninsula as being the desert land form.
- The availability of potable water is scarce and has access to saline water which cannot be drunk or used for irrigation.
- Therefore, industrially treated saline water removes salt from the sea water and then can be used for drinking and irrigation purpose.
Earth's air is made up of molecules of different gases that are not joined chemically, and a terminology which best describes air is mixture.
<h3>What is a mixture?</h3>
A mixture can be defined as a combination of two (2) or more substances which are present in varied proportion (unfixed ratios). Also, a mixture can be visibly seen with our na-ked eyes and separated by physical means.
<h3>The types of mixture.</h3>
In Chemistry, there are two (2) main types of mixture and these include the following;
From the above definition of a mixture, we can reasonably infer and logically deduce that the particles of a mixture do not have a set ratio on how to combine and they can be separated through the use of a physical separation technique.

Explosive eruptions tend to build up composite volcanoes.
A composite volcano evolved over tens of thousands of years as a result of several eruptions. The composite volcano is built up through eruptions, layer by layer, until it reaches heights of thousands of meters. Lava may have formed some layers, while ash, rock, and pyroclastic flows may have formed others. A composite volcano can also accumulate significant amounts of thick magma, which can clog up inside the volcano and force it to erupt violently.
Composite Volcano are fueled by a conduit system that accesses a magma reserve deep within the Earth. This magma can erupt either from a sizable core crater at the volcano's summit or from a number of vents scattered throughout the flanks of the composite volcano.
