Answer and Explanation:
Earths crust is broken into plates called tectonic plates. the plates move bc of convection currents in the earths mantle. convection currents are the movement caused with a liquid by the propencity of hotter and less dense matter to rise, and colder, thicker material to sink under the effect of gravitational pull, which as a result results in the transfer of heat.

<h3>Role</h3>
The Supreme Court plays a very important role in our constitutional system of government. First, as the highest court in the land, it is the court of last resort for those looking for justice. Second, due to its power of judicial review, it plays an essential role in ensuring that each branch of government recognizes the limits of its own power. Third, it protects civil rights and liberties by striking down laws that violate the Constitution. Finally, it sets appropriate limits on democratic government by ensuring that popular majorities cannot pass laws that harm and/or take undue advantage of unpopular minorities. In essence, it serves to ensure that the changing views of a majority do not undermine the fundamental values common to all Americans, i.e., freedom of speech, freedom of religion, and due process of law.
<h3>Impact</h3>
The decisions of the Supreme Court have an important impact on society at large, not just on lawyers and judges. The decisions of the Court have a profound impact on high school students. In fact, several landmark cases decided by the Court have involved students, e.g., Tinker v. Des Moines Independent School District (1969) held that students could not be punished for wearing black armbands to school to protest the Vietnam War. In the Tinker case, the Court held that "students do not shed their rights at the schoolhouse gate."
