In Brown v. Board of Education, the Supreme Court . upheld the decision in Plessy v. Ferguson
made segregation in all public accommodations illegal
concluded that separate educational facilities are inherently unequal
established the doctrine of "separate but equal"

Brown v. Board of Education of Topeka, 347 U.S. 483 (1954),[1] was a landmark decision of the U.S. Supreme Court in which the Court ruled that U.S. state laws establishing racial segregation in public schools are unconstitutional, even if the segregated schools are otherwise equal in quality. Handed down on May 17, 1954, the Court's unanimous (9–0) decision stated that "separate educational facilities are inherently unequal", and therefore violate the Equal Protection Clause of the Fourteenth Amendment of the U.S. Constitution. However, the decision's 14 pages did not spell out any sort of method for ending racial segregation in schools, and the Court's second decision in Brown II (349 U.S. 294 (1955)) only ordered states to desegregate "with all deliberate speed".

The Browns and twelve other local black families in similar situations then filed a class action lawsuit in U.S. federal court against the Topeka Board of Education, alleging that its segregation policy was unconstitutional. A three-judge panel of the U.S. District Court for the District of Kansas rendered a verdict against the Browns, relying on the precedent of the Supreme Court's 1896 decision in Plessy v. Ferguson, in which the Court had ruled that racial segregation was not in itself a violation of the Fourteenth Amendment's Equal Protection Clause if the facilities in question were otherwise equal, a doctrine that had come to be known as "separate but equal". The Browns, then represented by NAACP chief counsel Thurgood Marshall, appealed to the Supreme Court, which agreed to hear the case.

The Court's decision in Brown partially overruled Plessy v. Ferguson by declaring that the "separate but equal" notion was unconstitutional for American public schools and educational facilities.[note 1] It paved the way for integration and was a major victory of the civil rights movement,[4] and a model for many future impact litigation cases.[5]

In the Southern United States, especially the "Deep South", where racial segregation was deeply entrenched, the reaction to Brown among most white people was "noisy and stubborn".[6] Many Southern governmental and political leaders embraced a plan known as "Massive Resistance", created by Virginia Senator Harry F. Byrd, in order to frustrate attempts to force them to de-segregate their school systems. Four years later, in the case of Cooper v. Aaron, the Court reaffirmed its ruling in Brown, and explicitly stated that state officials and legislators had no power to nullify its ruling.

open this helps if not sorry:(:)

The Brown v. Board of Education Supreme Court case established that racial segregation in any and all public accommodations were illegal and unconstitutional.

the earth’s crust is broken into separate pieces called tectonic plates (fig. 7.14). recall that the crust is the solid, rocky, outer shell of the planet. it is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. both types of crust rest atop solid, upper mantle material. the upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.

each tectonic plate is free-floating and can move independently. earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. the term fault is used to describe the boundary between tectonic plates. most of the earthquakes and volcanoes around the pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. other observable results of short-term plate movement include the gradual widening of the great rift lakes in eastern africa and the rising of the himalayan mountain range. the motion of plates can be described in four general patterns:

collision: when two continental plates are shoved together

subduction: when one plate plunges beneath another (fig. 7.15)

spreading: when two plates are pushed apart (fig. 7.15)

transform faulting: when two plates slide past each other (fig. 7.15)
