Why do you think it was important for so many different groups to participate in the March on Washington?

Because this was a match for jobs and freedom from racial discrimination.

Explanation:

It was good for so many groups to participate in this match to Washington because the March was against injustice, and it was a match go freedom.

The March on Washington was a match for Jobs and Freedom. This political demonstration took place in Washington, D.C. in the year 1963. The march was orchestrated by civil rights leaders and they were marching in protest of racial discrimination and also they were showing support for several civil rights legislation they considered major which the congress was yet to give a rule on.

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)
