Geophysics S-waves in the outer core. This indicates that the outer core is liquid, because liquids cannot support shear. The outer core is liquid, and the motion of this highly conductive fluid generates the Earth's field. The inner core, however, is solid because of the enormous pressure. Reconstruction of seismic reflections in the deep interior indicate some major discontinuities in seismic velocities that demarcate the major zones of the Earth: inner core, outer core, mantle, lithosphere and crust. The mantle itself is divided into the upper mantle, transition zone, lower mantle and "D′′" layer. Between the crust and the mantle is
Women and the environment 1980s was an important decade for women in the environment. In 1980 the term 'ecofeminism' was born with two important events taking place. In April, 1980 the conference, "Women and Life on Earth: Ecofeminism in the 1980's" was held in Amherst, MA, the first in a series of conferences on ecofeminism. In November, 1980 the Women's Pentagon Action took place in Washington D.C.. when the group, "Women and Life on Earth" gathered to protest war, militarism, nuclear weapons and the effects on the environment. At its core, ecofeminism recognizes the link between the oppression of women and the oppression of
