EARTH'S LAYERS
LESSON 1
IN YOUR NOTEBOOK, WRITE A BRIEF DESCRIPTION OF WHY THE EARTH HAS LAYERS.
FOR YOUR NOTEBOOK:
Lesson 1: Earth's Layers
This is theoretical based on what we've learned by Earthquake Readings.
Earth's Layers
Inner Core - Earth's innermost layer. We believe it's a hot, solid metal ball.
9800 Degrees Fahrenheit! (5600 Degrees Celsius)
Would be liquid, but pressure keeps it solid and dense with Nickel and Iron.
Outer Core - Liquid metal surrounding the inner core.
Liquid metal moves around the solid metal inner core. Movement caused by severe radiation.
This movement generates a magnetic field around the Earth!
Iron and Nickel
Mantle - The thickest layer of the Earth.
Molten Magma filled with iron and magnesium.
Slowly circulates
Pushes Diamond crystals up to the surface through cracks in the crust.
Asthenosphere - Transitional semi-solid material between the Crust and Mantle. It's not a major layer, because it is part of the mantle.
Lithosphere - Transitional semi-solid material between the Crust and Mantle. Also not a major layer, because it is part of the mantle. Coolest part of the Mantle. Almost solid.
Crust - Earth's outermost layer. The Earth's crust floats like a boat on the molten rock below.
Filled with silicon and a lot less dense than what's below.
Cut into pieces called Tectonic Plates
