Continents are the surface parts of tectonic plates. Continental drift occurs when tectonic plates stop moving
Answer:
1. Continental drift occurs when tectonic plates stop moving.
2. Continental drift led to an increase in biodiversity.
Which of the following is a piece of evidence Wegener used to support nis hypothesis of continental drift? a) the puzzle-like fit of continental coastlines b) the similarity of rock groups on separated continents c) the presence of similar fossils on separated continents d) A and B only e) A, B and C
Answer:
The correct option is : e) A, B and C
Explanation:
The continental drift is the theory that continents of the earth have moved relative to the other continents over the period of time. Therefore, the continents appear and are said to be drifted or moved across the ocean bed. This theory was fully developed by Alfred Wegener in 1912. This hypothesis was supported by the following evidences
1. the fossils of the plants and animals are found on the shores of continents that were once joined.
2. The continental coastlines fit together in a puzzle-like manner.
3. The similarity in the rock groups present on the continents that were once joined.
According to the textbook, “Many experts predict that the largest increase in demand for oil in the coming years will come from increasingly industrialized economies with large populations…” (p. 140)
Can this be offset by measures taken in developed nations to address the energy–climate crisis? Why or why not? What potential strategies could be used to reduce the demand for energy in industrialized economies with large populations?
1. While there is always the possibility of being an offset, the fact point that the increasingly industrialized nations with rapidly growing large populations are constantly using more and more energy and the trend seems that it will continue. These nations have industries that grow exponentially, as well as exponentially growing populations, thus providing lot of labor force. Unlike the developed countries, these countries don't bother with investments in renewable sources of energy, but they use strictly the fossil fuels, which will just make an even bigger environmental problem in the future.
2. The best strategies that can be used by these nations to not be such big consumers of the fossils fuels is that they invest, be it on their own or with foreign aid, into the renewable resources. Most of these nations have great potential for development of such energy sources. We can take Nigeria for example, which has lot of sunny days, as well as great hydropotential, so it can focus on these two for production of energy. Pakistan is a very windy nation, and it also has lot of sunny days, and on top of it has lot of uninhabited land that can be used, so it can focus on these two for production of energy.

What is the Declination of the Celestial Equator? A) 45 degrees B) 90 degrees C)0 degrees D) Horizon
Answer:
The correct answer is option c) 0 degrees
Explanation:
In the equatorial coordinate system there are two angles which can help in locating a point on the celestial sphere. Those two angles are declination and hour angle, where declination's can be measured along the hour circle and towards the north and south of the celestial sphere. So from this information we can say that if an object is at celestial equator it would have a declination of 0 degree , with if object being at north will have +90 degree and at south it will have declination of -90 degree.

The continents are light in color because they contain:
A. silicon and aluminum
b.iron and nickel
c.iron and quartz
d.silicon and magnesium
Answer:
The continents are light in color because they contain:
( A ) silicon and aluminum
Explanation:
Continental crust -
Continental crust contains more light-colored rocks than oceanic crust .
The continents crust are light in color because they contain:
silicon and aluminum but in the oceanic crust silicon and aluminium not present.
In oceanic crust only silicon and magnesium is present , which is responsible for the dark crust of ocean.
Hence,
Correct option is - ( A ) silicon and aluminum
Final answer:
Continents are light in color mainly due to the presence of silicon and aluminum, which are components of quartz and feldspar forming light-colored granitic rocks.
Explanation:
The continents are light in color because they contain a specific combination of minerals. Based on the geological composition of continental rocks, which are rich in the light-colored minerals quartz and feldspar, forming granite, the correct answer to the question is:
A. silicon and aluminum
. These minerals are prevalent in granitic rocks, which are characteristically light in color and form much of the continental crust. The presence of high levels of silicon gives these rocks their light color, and granite is a clear example of this kind of rock, often found in the Earth's continental areas.

Metal sulfides associated with hydrothermal vents Evaporite minerals formed from restricted open ocean circulation with high evaporation rates d. Carbonate deposits in tropical e. None of the above
Answer:
Evaporite minerals formed from restricted open ocean circulation with high evaporation rates
Explanation:
Salts like halite and gypsum are called evaporites.
Evaporites are chemical sedimentary rocks that forms when water in a basin(oceans, lakes) are restricted to flow and evaporation causes precipitation of the minerals dissolved in the water.
Halite and gypsum form insolube precipipate that accumulates over a long period of time in such an environment. The formation of evaporite largely depends on the dissolved load of a sediment and the environment of depositon of the load.

Successive West African kingdoms Ghana, Mali, and Songhay a) drew upon the agricultural fertiliity of the Inland Niger River Delta b) dominated the urban centers Gao, Timbuktu, and Jenne Jeno c) controlled the trade of gold going North and salt going South d) all of the above
Answer:
The correct option is c) controlled the trade of gold going North and salt going South
Explanation:
the option a) can't be true because Niger river doesn't flow through Ghana and Songhay (but it does flow through Mali), so therefore these successive western African kingdoms can't drew upon the agricultural fertility of the inland Niger river delta.
since the option a) is not true , then we can conclude that the option d) all of the above will also not be true.
while the successive kingdoms of Mali, Ghana, Songhay do have dominance in the trade of gold and salt in the region between Sub Saharan and North Africa, so on the basis of this we can say that it is possible that these kingdoms control the trade of gold going North and salt going South.
The least explosive volcanic eruptions usually come from which type of volcano?
calderas
shield volcanoes
composite cones
cinder cones
plug domes
Answer:
The least explosive volcanic eruptions is from - shield volcanoes.
Explanation:
Shield volcanoes -
Shield volcanoes are made up of fluid lava.
They are created by slow accretion of thousands of highly fluid lava flows called the basalt lava. Then the basalt lava spread over and cool down to thin layer.
Shield volcanoes are those which erupts less ,
Reason being the composition of the magma , i.e., the magma is less viscous and less gaseous basltic magma.
If the magma contains high viscosity and high amount of gaseous particles like a granitic magma then it will erupt violently.

Flood tides describe a tide that occurs as the water rises in the basin during a change from low tide to high tide.
Based on your knowledge of blackbodies, should the hotter star or the cooler star be more luminous
Answer:
Hotter star is more luminous.
Explanation:
A blackbody is an object that absorbs all the radiation incident on it. It does not reflect or let the radiation pass through it.
When the radiations are absorbed, the blackbody heats up. This results in the emission of radiation by the blockbody.
The amount of radiation the black body emits, depends upon the temperature of the blackbody. Therefore, greater the temperature of the blackbody, more the emitted radiation.
A star is very similar to a blackbody. So, if two stars are compared, then the hotter star will emit more light as compared to the cooler star.
Therefore, the hotter star will be more luminous than the cooler star.

Explanation:
Ego Integrity Vs despair
According to Erickson, the personality development of a human being is characterised by eight stages psychosocial development staring from infant to adulthood.
Ego integrity Vs despair is the final stage and the eight stage of Erickson's theory of psychosocial development. It is believed that this stage starts at the age of 65 years and continues till death. After we attain 65 years of age, we tend to become unproductive and we feel guilt of our past and a sense of depression feels our mind and we feel depressed and full of guilt. But if we achieve success at this age of life, it will lead to a virtue of wisdom. Thus wise people at this age has a sense of both integrity and despair.
Wisdom is associated with the stage of Ego Integrity vs. Despair, and the final stage of life is a time of ego integrity or despair.
Explanation:According to Erikson, wisdom is associated with the stage of Ego Integrity versus Despair. This stage occurs in late adulthood when individuals reflect on their lives and either experience a sense of satisfaction and fulfillment (ego integrity) or feelings of regret and despair (despair).
The final stage of life is a time of ego integrity or despair. It is a time when individuals look back on their accomplishments and experiences, and assess whether they lived a meaningful life. If they feel a sense of satisfaction and acceptance, they will develop ego integrity. However, if they feel a sense of disappointment or regret, they may develop despair.

Orographic lifting refers to
a.convection stimulated principally by local heating
b. lifting along the edges of conflicting air masses
c. forced uplift due to the presence of a physical barrier
d.none of the above
The correct answer is C. Forced uplift due to the presence of a physical barrier.
Explanation
When a current of air finds a barrier in its way, for example, a mountain, it is forced to overcome this obstacle, in this way, the air surrounds the relief that opposes and overcomes the barrier which is known in Geography as Orographic lifting.
This collision between clouds and land reliefs causes the phenomena known as windward and leeward, in which a side of the mountain works las a filter, because it takes the humidity of the clouds that clash in the mountains(windward), while the other side of the mountain or relief, receives dry air, making it a dry environment and in some cases arid (leeward). So, the correct answer is C. Forced uplift due to the presence of a physical barrier.

Do you think that some of Lumumba's ideals still live on in contemporary Africa?
The national hero of the DR Congo, Patrice Lumumba, was a man that had lot of ideas, good and healthy ones, as to how the African continent should be and prosper. Some of his ideals was that the African countries become independent, all of them to be in good relations and support each other, form an organization through which there will political and economic collaboration between the African nations, to force the tribalism, ethnic, and religious rivalry out of the African mindset. In the present, these ideals still live on among millions of people, but unfortunately it seems that they are a minority. The majority seems to still engage in what Lumumba wanted to eradicate. The collaboration between the nations is not the best, being more tense than good, and lot of people try to migrate out of the continent instead of trying to make it a better place for living.

The most recent Ice Age occurred during the________. Jurassic period Quaternary period Mesozoic era
Answer:
Quaternary period
Explanation:
The last Ice Age on Earth occurred during the Quaternary period. This Ice Age only ended around 10,000 years BC, so very recently. During this period, big portions of the Earth were under ice, with approximately half of North America, as well as half of Eurasia being covered in ice. The mountains around the globe too were covered in glaciers. Because there was so much water trapped in the ice sheets and glaciers, the sea levels were much lower, which opened up lot of land-bridges between the islands and continents, which turned out to be crucial for the human migrations around the globe.
