Theodore Roosevelt was the New York politician who accused a reporter of being a muckraker during Harlem Renaissance. This term was coined by Roosevelt himself, for the journalists who were reform-minded and attached established institutions as corrupt.
Answer:
An independent or nonpartisan politician is a politician not affiliated with any political party. There are numerous reasons why someone may stand for office as an independent.
Some politicians have political views that do not align with the platforms of any political party, and therefore choose not to affiliate with them. Some independent politicians may be associated with a party, perhaps as former members of it, or else have views that align with it, but choose not to stand in its name, or are unable to do so because the party in question has selected another candidate. Others may belong to or support a political party at the national level but believe they should not formally represent it (and thus be subject to its policies) at another level.
In running for public office, independents sometimes choose to form a party or alliance with other independents, and may formally register their party or alliance. Even where the word "independent" is used, such alliances have much in common with a political party, especially if there is an organization which needs to approve the "independent" candidates.
Plate tectonics is the theory that explains how Earth's land masses are in constant motion. Before this theory was discovered, Alfred Wegener found out about the continental drift. Its the hypothesis of how the continents drifted over the ocean bed.
The continental drift led to the theory of plate tectonics. The main reason that led to the movement of the continents is because of the movement of the plates in the lithosphere.
Plates are massive, irregularly shaped slabs of solid rock, generally composed of both continental and oceanic lithosphere.
The intense heat in the Earth's core make the plates to move.
Humans can be affected by volcanic events, sea level rise, and earthquakes, all of which are related to plate tectonics.
