What was the major improvement to air quality contributed by the 1990 amendments to the Clean Air Act?

Answers

Answer 1

Finding affordable strategies to minimize air pollution was one of the key modifications made to the 1990 Clean Air Act amendment.

The Clean Air Act is a federal law in the United States that tries to regulate air quality and lessen pollutants that can harm it. This law stipulates a set of rules that must be adhered to throughout the national territory, restricts the number of pollutants that major companies can release into the atmosphere, and establishes rules to manage the pollution's effects (such as acid rain, for example). Over the years, this law has experienced some changes, one of which was in 1990, when emphasis was placed on the necessity of coming up with practical measures to lessen air pollution.

Why did the East India trading company fail?

Answers

Incorporated in England in 1600 and eventually becoming British, the East India Company was disbanded in 1874. It was established to engage in commerce with the East Indies and subsequently, East Asia, in the Indian Ocean area.

The East India Business collapsed due to pervasive corruption in the organisation. The company progressively lost its economic monopoly and political power. In 1858, the British crown nationalised its Indian holdings. By virtue of the East India Stock Dividend Redemption Act, it was legally liquidated in 1874.

Initially founded in 1600, the East India Company was intended to act as a commercial organisation for English merchants, primarily to engage in the East Indian spice trade.

Nordic countries share so many similar characteristics because in the nineteenth century the countries all went about similar changes so they ended up going down same paths.

Nordic countries historically had a low proportion of serfs compared to independent farmers, a tiny population, and few metropolitan areas. When compared to Continental Europe, the nobility was neither very wealthy or influential. They all converted to Protestantism quickly.

Up until the previous few centuries, they were incredibly homogeneous in terms of race, religion, and culture. Over the past 200 years, none of them have played a significant role in European politics or as major colonial powers. In each of them, social democracy has played a significant role.

Why the convection is so important in the mantle of the Earth?

Answers

Convection plays an important role in the mantle of the Earth. It helps to evenly distribute heat and energy throughout the layer, preventing it from becoming unstable.

It also helps to drive the movement of tectonic plates, and is essential for the formation of geological features. Convection is the process by which heat is transferred through the movement of fluids. In the mantle, convection occurs when hot material rises and cold material sinks.

This process is driven by differences in density, which are caused by differences in temperature. Hot material is less dense than cold material, so it rises up and is replaced by cold material that sinks down. This creates a continuous circulation of hot and cold material, which helps to evenly distribute heat throughout the mantle.

This process of convection is essential for the mantle to remain in a stable state. Without the circulation of heat, the mantle would become extremely hot near the core, and very cold near the crust. This could potentially cause the mantle to become unstable, leading to earthquakes and volcanic activity.

The convection process also helps to drive the movement of tectonic plates. As the mantle convects, it creates pressure and movement along the boundaries of the plates. This pressure can cause the plates to slowly move, resulting in the formation of mountains, valleys, and other geological features.
