Abundance of the chemical elements in the Sun and outer planets is similar to that in the universe. Due to solar heating, the elements of Earth and the inner rocky planets of the Solar System have undergone an additional depletion of volatile hydrogen, helium, neon, nitrogen, and carbon (which volatilizes as methane). The crust, mantle, and core of the Earth show evidence of chemical segregation plus some sequestration by density. Lighter silicates of aluminum are found in the crust, with more magnesium silicate in the mantle, while metallic iron and nickel compose the core. The abundance of elements in specialized environments, such as atmospheres, or
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.
