Answer:
A)
The Ganges Plain stretches across northern India and is home to one-tenth of the world’s population.
<span>The <u>Cultural Landscape</u> is a
theory that states that the sum affects the human population has on the
environment. It means that any changes that the humans applied to the environment
will be experienced by them. There are a lot of places or things that humasn
affect the environment. An example of this is the pyramid of Egypt. The Egyptians
changed the topography of th land in the areas where pyramids were built. At the
same time, it also affected their lifestyle. </span>
A man named Alfred Wegener proposed that all the continents were one, giant continent which he called Pangaea. He backed up this idea with evidence from other fossil remains. Fossils from animals native to a certain country were appearing on other countries from much further away.
The International Date Line (IDL) is a line that separates the world into two hemispheres. It was first established in 1884 during the International Meridian Conference which was attended by 26 countries. It is located at the 180° longitude, which is the east of Greenwich, United Kingdom.
The International Date Line does not follow a straight line because it has to avoid countries or groups of islands. The main purpose of the zigzag pattern of the IDL is to avoid confusion regarding time.
The IDL is important because it's the basis for our time zones. Back in the nineteenth century, scientists as well other professionals in various industries proposed to adopt the 24 time zone system which centered on the IDL's principle of adopting the proper "time". The IDL divides the world into two dates: the East of the IDL is a day behind compared to the West of the IDL.
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.
