Answer:
Time-space compression refers to the set of processes that cause the relative distances between places (i.e., as measured in terms of travel time or cost) to contract, effectively making such places grow “closer.” The idea of a “shrinking world” is not new and, in the face of rapid advances in travel, such as the jet ...
Explanation:
Italian astronomer Galileo Galilei discovered four of Jupiter's moons , in year 1610 . Now these are known as Io, Europa, Ganymede, and Callisto. Io is innermost of these four moons and one of the most volcanically active planetary object still discovered. These moons are very much different from any other planetary body in every respect. The Voyager spacecraft pictures show that the surface of the moon io is completely covered by volcanoes and lavas rather being covered by pitts and craters. this gives the surface a very young look. The main cause of the intense volcanic activity found out here is the strong gravitational force created at the center of the moon from the Jupiter and Europa. Due to the synchronous rotation with Jupiter, solid materials at the surface of io bulges up just like the tidal motions of the oceanic water in the case of Earth. This repeated bulging causes the materials to get hitted up in a manner similar to repeatedly stretching and smashing a clay ball or rubber band. This enormous amount of heat generated in the process melts rock materials at depth and results in widespread volcanisms.
Hypotheses to explain different levels of volcanism:
a) This is very much evident that the volcanic activity is largely driven by the gravitational forces of the Jupiter. If the moons are at different distances from the large planet then the gravitational pull will be also varying for the moons and this will cause differential amount and types of volcanic activity at the moon's surface.
b) In case of io, the moon is largely made up of iron and iron sulphide core and a silicate outer surface. This silicate outer surface of the moon melts down to create the widespread volcanic activity. In case of Europa the outer surface is made up of vast quantity of water and ice. So there is lesser chance of volcanic activity in this moon. So the volcanic activity is greatly controlled by the lithological composition of the moon.
c) There is a vast amount of sulphur present at the interior of io which gets degassed and comes to the surface to create the fierce nature of the volcanisms. These gases are essential for a violent volcanism, and controls the nature and level of volcanism.
France is the birthplace of cinema and was responsible for many of its significant contributions to the art form and the film-making process itself.[3] Several important cinematic movements, including the Nouvelle Vague, began in the country. It is noted for having a particularly strong film industry, due in part to protections afforded by the French government.[3]
Apart from its strong and innovative film tradition, France has also been a gathering spot for artists from across Europe and the world. For this reason, French cinema is sometimes intertwined with the cinema of foreign nations. Directors from nations such as Poland (Roman Polanski, Krzysztof Kieślowski, and Andrzej Żuławski), Argentina (Gaspar Noé and Edgardo Cozarinsky), Russia (Alexandre Alexeieff, Anatole Litvak), Austria (Michael Haneke), and Georgia (Géla Babluani, Otar Iosseliani) are prominent in the ranks of French cinema. Conversely, French directors have had prolific and influential careers in other countries, such as Luc Besson, Jacques Tourneur, or Francis Veber in the United States.
Another element supporting this fact is that Paris has the highest density of cinemas in the world, measured by the number of movie theaters per inhabitant,[4] and that in most "downtown Paris" movie theaters, foreign movies which would be secluded to "art houses" cinemas in other places are shown alongside "mainstream" works. Philippe Binant realized, on 2 February 2000, the first digital cinema projection in Europe, with the DLP CINEMA technology developed by Texas Instruments, in Paris.[5][6][7] Paris also boasts the Cité du cinéma, a major studio north of the city, and Disney Studio, a theme park devoted to the cinema and the third theme park near the city behind Disneyland and Parc Asterix.[8]
France is the most successful film industry in Europe in terms of number of films produced per annum, with a record-breaking 300 feature-length films produced in 2015.[9] France is also one of the few countries where non-American productions have the biggest share: American films only represented 44.9% of total admissions in 2014. This is largely due to the commercial strength of domestic productions, which accounted for 44,5% of admissions in 2014 (35.5% in 2015; 35.3% in 2016).[10] Also, the French film industry is closer to being entirely self-sufficient than any other country in Europe, recovering around 80–90% of costs from revenues generated in the domestic market alone.[11]
The correct answer is - greenhouse gases.
The humans have been having a very big impact on the composition of the atmosphere in the past century, and that has started to result into changes in the climate patters all over the globe.
The main problem appears with the huge amounts of greenhouse gases released into the atmosphere, mostly carbon dioxide, but also methane. These two gases have properties that enable the greenhouse effect, which means that they are able to trap bigger amount of heat in the Earth's atmosphere, thus making it warmer.
If the ongoing trend continuous with the release of the greenhouse gases there will for sure be devastating effects on everyone and everything on the planet not so far in the future.
The correct answer is - A. Rap music and country music are both popular in the United States.
The rap music and the country music are both popular in the United States. This is a nice example of cultural diversity because these two music types have different origins. While the country music is a music type created by the white settlers in America, and over time grew to be the traditional music of the United States, the rap music is a music type that was created by the black people in America. Despite being created by different racial and cultural groups both of these music types are popular in the United States and they have fans that are both white and black.
