Try to explore:
(1) People say that the area of the Red Sea will continue to expand and eventually form a new ocean. Is that right? Try to explain why
(2) What impact will the influx of rural population bring to the city? Please share your opinion
Best answer:
(1) The Red Sea is located between the Indian Ocean plate and the African plate, and the two plates have undergone tension and fracture movement, making the area of the Red Sea continuously expand;
(2) The city has more employment opportunities, better education conditions, better medical conditions, etc., attracting a large number of rural population to the city, making the city develop rapidly, while bringing a series of problems to the city, such as traffic congestion, housing shortage, environmental pollution, etc
So the answer is:
(1) Yes; Because the Red Sea is located in the tension zone of plates (Indian Ocean plate and African plate), the area will continue to expand;
(2) Promote the economic development of the city; At the same time, it will bring a series of problems to the city, such as traffic congestion, housing shortage, environmental pollution, etc
Answer analysis:
There is no explanation for this question
Test core:
Plate drift theory: a theory that explains the crustal movement and the distribution and evolution of land and sea. The large-scale horizontal movement between continents and between continents and ocean basins is called continental drift. According to the theory of continental drift, all continents on the earth were once unified huge landmasses before the Mesozoic era, called Pangaea or United Ancient Land. From the beginning of the Mesozoic era, Pangaea split and drifted, gradually reaching the current position. Land reclamation: Land reclamation refers to the transformation of the original sea area, lake area or river bank into land. For coastal cities with more mountains and less flat land, land reclamation is an effective way to create flat land for urban development. Many large coastal cities, such as Tokyo, Hong Kong, Macao and Shenzhen, use this method to make flat land. Volcanic seismic zone: There are two major seismic zones around the world: the Pacific Rim seismic zone and the Mediterranean Himalayan seismic zone. The former concentrates more than 80% of the shallow earthquakes (0-70km), almost all of the medium earthquakes (70-300km) and deep earthquakes (300-700km) in the world. It is distributed around the Pacific Ocean, starting from the southern end of South America, extending northward along the west coast to Alaska in North America, and turning westward through Aleutian Islands, Kamchatka Peninsula, Kuril Islands to Japan.
