true or false, Polar orbiting satellites offer the advantage of imaging clouds directly below their orbit, rather than at an angle such as experienced by a geostationary satellite.

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.

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.

Education prepares individuals for the job market, fosters personal development, contributes to nation-building, upholds cultural values, and influences career paths, income, and life choices.

A true educator should aim not only to prepare students for the job market but also to contribute to their overall development as individuals capable of critical thinking, ethical reasoning, and becoming responsible members of society.

Regarding happiness, while education may not be the sole gateway to happiness, it can provide the tools and opportunities for individuals to pursue fulfilling lives and careers. Moreover, education plays a crucial role in nation-building, particularly in the Caribbean, by fostering social cohesion, promoting cultural values, and driving economic growth through an educated workforce.

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.

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.

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:

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.

The hard caprock of mesas in the Thunder Bay - Nipigon region is formed from Diabase, an igneous rock resistant to weathering.

The rocks that form the hard caprock of mesas in the Thunder Bay - Nipigon region are Diabase. This is a type of igneous rock that is particularly resistant to weathering and erosion, which allows it to protect the softer rocks underneath and gives mesas their characteristic flat-topped shape. Diabase caprock is formed from magma that cools and solidifies within the Earth's crust. The resistance to weathering helps in preserving the landform's shape against the forces of nature.

It is true that subtropical deserts are centered around 20 degrees to 30 degrees north and south latitude.

The atmospheric environment of subtropical climate inhibits precipitation as the air always descends with clear skies, elevated inversions. Most of the Earth's tropical desert climate occurs between 15 to 30 degrees north and South latitude.

Temperatures are usually high (21-32) and on a daily basis variations are extreme. The deserts are subject to frequent fog and low-level clouds. The cooling results from the oceans and coastal waters give rise to cold currents. The maritime air penetrates less frequently as the high and low sun-monsoonal winds blow along the coast.

Answer:

1. Continental drift occurs when tectonic plates stop moving.

2. Continental drift led to an increase in biodiversity.

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.

According to Erickson, wisdom is associated with the stage of ---

A). Ego integrity and despair

The final stage of life is a time of ---

D).Ego integrity and despair

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.

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.

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 factor that would have the net effect of making a place warmer during summer would be that it is in the middle of a landmass.

The reason why a warmer summer would be present at the middle of a landmass is because landmass:

1. Has a lower specific heat capacity, and therefore can be heated up quickly, through receiving insolation from the sun.

2. Land is opaque, therefore insolation only concentrate in shallow areas, making the surface temperature increase.

3. There is no mixing of warm and cold layers, along with the lack of presence of evaporation, there would be less cooling

In sum, the above effects can be called continental climate, and thus the middle of a land mass is cooler.

For your reference, here's why the other options are not correct:  

At a high elevation near an ocean - near the ocean would mean it has a maritime effect and therefore a cooler summer.

At a high latitude - with the less dense air, heat will be absorbed faster resulting in faster heat loss hence a cooler summer.

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.
