The 3 main layers are the crust, the mantle, and the core. The crust consists of everything you see- dirt, rock, minerals, and everything you can see. We live on the crust, and it floats around on the magma in pieces we call continents. The next layer is the mantle, which is where all the magma is- this is what the crust floats on. It consists of molten rock and minerals; the bottom layer of the crust is continually melting under the extreme heat, but it is replaced when volcanoes spew the magma back onto the surface. The last layer is the core, an extremely fast-spinning ball of heavy metals. It is split into two layers; inner and outer core. The outer core is mostly an alloy of nickel and iron with some other heavy metals thrown in, like platinum and gold, but the inner core is almost solid iron. It is so hot that it should be melted, but the pressure of everything on top of it makes it so it has nowhere to melt to, keeping it solid.
Hope this helps!!! ^_^

El impacto de la industria en el medio ambiente es directa y ha provocado consecuencias desastrosas para el medio ambiente por el grado de contaminación que producen las industrias.
Al parecer a las industrias solo les interesa ganar dinero, sin importante el daño que le provocan al medio ambiente con tanta contaminación del aire, contaminación del agua y la contaminación auditiva.
Esta contaminación envenena las aguas, envenena el aire, enferma a los animales, afecta a la biodiversidad en general (animales, árboles, vegetales, mares, ríos, bosques)
Existen organizaciones ambientalistas que trabajan para preservar los ecosistemas, pero se requiere de mejores leyes ambientales y que los gobiernos las apliquen para que las industrias dejen de contaminar tanto.
The U.S. Federal and State Governments are similar because both levels of government have the power to collect taxes from citizens. States do not have the power to declare war on other nations, nor print currency or control banks. Businesses within certain states can trade with foreign countries, but states do not control trade policy for these businesses.
