    Default Friday Trivia: Earth Layers

    The earth has three distinct layers.

    At its center is a super-hot metallic core. Surrounding that is the mantle, which is about 1,700 miles deep.

    The outer layer is the crust. And between the mantle and the crust is a defined zone known as the Mohorovicic discontinuity, or the Moho. It's named for Croatian seismologist Andrija Mohorovicic, who demonstrated its existence by studying the patterns of seismic waves from an earthquake that hit Croatia in 1909.

    Thanks for sharing. I'm a little more knowledgeable every time you post.

    Enjoy life and do what makes you happy. Everything else will follow.

    Every day I try to do one thing that challenges my comfort zone.

    The core is in two layers... inner (which is solid), outer ( which is liquid) and scientist have determined that they spin in opposite directions. They also think that the core spins faster than the earth.
