Answer:
Democracy is a form of government in which the rulers are elected by the people. One chief factor common to all democracies is that the government is chosen by the people. It also helps students to demarcate between democratic and non-democratic governments. From the non-democratic government, take the example of Myanmar, where rulers were not elected by the people. Those who were in charge of the army of the country took over as rulers and people had no say in this decision. Dictators like Pinochet (Chile) are not elected by the people. This also applies to monarchies.
Answer:
C. Turbine
Explanation:
Most power-generation technologies use a form of turbine to create electricity. The turbine is forced to spin because of an external force applied to its blades, and that movement against a fixed generator created electricity.
In a gas or steam plant, the gases force the movement of the turbine.
In water-based plants, it's the water pushing the blades (like in a dam).
In a wind turbine, it's the wind pushing the blades.
And so on.
Answer:
Industrialização e urbanização.
Explicação:
A industrialização e a urbanização são as principais causas de degradação ambiental no mundo atual, porque a industrialização e a urbanização produzem uma grande quantidade de poluição que afeta adversamente o meio ambiente. Antes da industrialização, a concentração de gases de efeito estufa, como carbondóxido e monóxido de carbono etc. na atmosfera, é baixa, mas após a industrialização, essa concentração aumenta, causando o aquecimento global ao bloquear a radiação solar. A industrialização e a urbanização também poluem os corpos d'água e a vida dos animais marinhos está em perigo.
