The mesosphere burns up most meteors and asteroids before they are able to reach the earth's surface.The mesosphere is the coldest atmospheric layer surrounding the earth. It becomes cold enough to freeze water vapor in its atmosphere into ice clouds.
<u>Answer</u>:
Globalisation makes the world shrink and flatten it in all sectors.
<u>Explanation</u>:
In the ancient and medival world, only labours were allowed to travel between the countries. IT revolution paves its way for the jobs to be exchanged between the countries and it leads to service growth in the developing countries.
After social media's tremendous growth, information gets transferred easily through various social media platforms. Knowledge and technology transfer between the countries generates more employment even in the under developed areas. India gained a generous amount of software and BPO jobs from the developed countries to increase their GDP since 1990s.
It is very easy. It is a lyric monologue done by the poetic abstract voice to directly send his message to the reader.
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.
