The correct answer is - 251 to 500.
The Ganges River basin is one of the most densely populated areas in the world. The average population density of this area is 390 people per square kilometer. The reason for the high density of the population in this area is that the Ganges River basin has been providing good living conditions for the people for thousands of years. The area has the Ganges River, as well as numerous other rivers, very fertile soil, nice climate, thus it has always been a very popular place for living in the Indian subcontinent. As it has been a densely populated area ever since people started living there, the trend continued over the centuries, and the population was constantly increasing. Numerous large cities have been built, and the region has been developing intensely in the past several decades, resulting in even more people being attracted to this area, thus contributing further to the high population density.
Answer:
Answer is option C (protoplanets).
Explanation:
During the formation of the solar system, a giant cloud of molecular dust collapsed to form stars, which were surrounded by a cloud of gas. The dust and other particles inside the cloud collide and merge together into larger mass through the gravitational and other forces. They continue to grow and become large enough to gravitationally attract other small celestial objects to form protoplanets. Some of the protoplanets continue their growth through the process called accretion and form planets.
Planetesimals - The small celestial objects formed during the early stages of the creation of the solar system.
Protoplanets - The objects formed when planetesimals became large enough to attract their neighboring celestial bodies through the force of gravity and grow by the process known as accretion, where they collide and merge together into larger bodies.
Extrasolar planets - The planets found outside our solar system (orbit another star, not the Sun).
The correct answer is A. Pollution from coal fires caused over 4,000 deaths, leading the British government to change their outlook on pollution.
Explanation:
In December 1952 and during 5 days the city of London was covered by a thick fog. This was the result of a high amount of pollutants released by coal fires in power plants and houses heating systems along with cold weather conditions. This did not only lead to low visibility but had serious effects on the citizens in London as thousands had respiratory problems and around 4,000 died.
Additionally, this event triggered concerns between the citizens of England and made the government consider the use of coal and the pollution. Indeed, after this event, different laws were created to reduce the air pollution in cities such as London. According to this, the statement that summarizes the effects of this event is A.
