ANOTHER 50 PTS MARKING BRAINLIEST The theory of continental drift stated that, at one time, the surface of Earth had one big continent that broke up and began to drift apart to eventually form Earth as we see it today. This theory was revised to become the theory of plate tectonics. This theory explains why the continents drift, why mountains form, and why volcanoes erupt. Which of these statements best explains why the theory of continental drift was revised to become the theory of plate tectonics? Continental drift was proven false by the completely new theory of plate tectonics. Scientists preferred the term plate tectonics over continental drift, so they changed the name. New evidence did not support the theory of one big continent, so the theory of plate tectonics was accepted. The theory of plate tectonics better explains the changes in the continents than the theory of continental drift.

The presidential primary elections and caucuses held in the various states, the District of Columbia, and territories of the United States form part of the nominating process of candidates for United States presidential elections. The United States Constitution has never specified the process; political parties have developed their own procedures over time. Some states hold only primary elections, some hold only caucuses, and others use a combination of both. These primaries and caucuses are staggered, generally beginning sometime in January or February, and ending about mid-June before the general election in November. State and local governments run the primary elections, while caucuses are private events that are directly run by the political parties themselves. A state's primary election or caucus is usually an indirect election: instead of voters directly selecting a particular person running for president, they determine the number of delegates each party's national convention will receive from their respective state. These delegates then in turn select their party's presidential nominee. The first state in the United States to hold its presidential primary was North Dakota in 1912, following on Oregon's successful implementation of its system in 1910.
