Crude oil are products that are formed due to the long term decomposition of plants and animal matter over the years. 4 million barrels of crude oil are produced and petrochemicals are chemicals that are produced from petroleum and their byproducts. Proven oil reserves are estimated to produce the calculated amount of oil and unproven oil reserves may or may not reach the calculated amount of oil. Conventional crude oils are alternative source which are used for crude oil.
Explanation:
The main process for the extraction of crude oil is drilling and when a place is tapped for the presence of crude oil by the geologist they set up huge rigs and start the extraction process.
Most of the worlds economy is mainly dependent on the crude oil because it is the core for all the oil products. The peak production of the oil well is the time in which the production reaches its maximum value and after which there will be a decline in the production of the crude oil
When petroleum is refined the by products that are obtained are called as petrochemicals some of the examples are natural gas, renewable resources and they are important because they have many commercial uses
The two types of unproven oil reserves are probable and the possible oil reserve the probable reserves are estimated to produce 40% confidently and the possible reserves are proven to produce 10%
The major advantages of conventional crude oil is they can be refined they can be used as lubricants they produce valuable gasoline products and they have become an integral source of transportation. Some of the disadvantages are prolonged use can cause damage to the environment and can cause high amount of pollution.
b. False
b.Large-scale oil spills lead directly to wetlands becoming deserts.
c.Large-scale oil spills are damaging to water quality, aquatic life, and bird populations.
d.Large-scale oil spills can lead to an increase in sea levels through glacial melting.
The correct answer is - c. large scale oil spills are damaging to water quality, aquatic life, and bird populations.
Oil spills are very big disasters that affect the environment and the ecosystems in the worst way possible. The water is contaminated to a degree where it can not be used for anything, and the oil it self needs lot of time to dispose so that the water returns to its previous state. The aquatic life dies out rapidly, all of the species affected by this die out of poisoning and the ecosystem in that place is totally ruined. The sea birds are also affected heavily because they dive into the water to hunt, and when there's oil their wings and bodies get covered in it and they are not able to fly, and either drown or slowly die on the shores.
b. They distort scale and landmass shape.
c. They distort lines of latitude and longitude, while accurately showing landmass and oceans.
d. They cannot include enough detail to be useful.
Answer:
b. They distort scale and landmass shape.
Explanation:
Maps are an attempt to represent regions as faithfully as possible. But there is an obvious difficulty in representing curved or three-dimensional objects, such as the earth, on a flat, two-dimensional surface.
So distortions always occur, that is, some parts of the map will not correspond exactly to what is being represented. It's like opening a ball and trying to stretch it to make it flat like a sheet of paper. You will not be able to make it flat unless you tear the edges, deforming it.

The flag of Angola is having the symbol with a half circle shape is a part of three symbols, that are collectively chosen to relate to the flag of old Soviet Union.
Further Explanation:
The flag of Angola is horizontally divided into red and black parts. It also consist of the symbol of a star, a half of the cogwheel and a machete. The red color of the flag signifies bloodshed during Angola Independence struggle and black color signifies Africa. The symbol of half of the cogwheel represent industrial worker, a star represents socialism and a machete represents peasantry.
The Soviet Union had a red flag with symbols of hammer, star and sickle. The hammer represents industrial worker, sickle represents peasants (agriculture workers) and star represents the communist party of the Soviet Union.
Therefore, the flag of Angola with the symbols of a star, a half of the cogwheel and a machete is related to the flag of Soviet Union.
Therefore, the flag of Angola is having the symbol with a half circle shape is a part of three symbols, that are collectively chosen to relate to the flag of old Soviet Union.
