PALE BLUE DOT Pale Blue Dot is a photograph of planet Earth taken on February 14, 1990, by the Voyager 1 space probe from a record distance of about 6 billion kilometers Voyager 1 was commanded by NASA to turn its camera around and take one last photograph of Earth across a great expanse of space at the request of astronomer and author Carl Sagan.

HOW DO WE KNOW THAT THE EARTH IS LAYERED?

WHO FIGURED IT OUT?

WHAT THE LAYER IS VS. WHAT THE LAYER DOES

DENSITY INCREASES FROM THE CRUST TO THE INNER CORE

CONVECTION CURRENTS TRANSFER THE CORE’S HEAT What’s a convection current? Cycle of heat transfer: warm matter rises, cold matter sinks

EARTH’S CORE IS AS HOT AS THE SURFACE OF THE SUN! 6000°C Thermal energy from the Earth’s formation drives – Cycling of matter between layers – Earth’s magnetic field

CONVECTION CURRENTS TRANSFER THE EARTH’S HEAT Radioactive decay in the Earth’s crust and mantle add heat Convection in the mantle drive plate tectonics Convection in the outer core drives the magnetic field

MATTER IS CYCLED BETWEEEN THE CRUST AND THE MANTLE AT PLATE BOUNDARIES Hot mantle material rises to form new crust where plates are pulled apart Cold crustal material sinks back into the mantle where plates are pushed together

The flow of matter in the outer core generates Earth’s magnetic field CONVECTION IN THE OUTER CORE

HOW DOES CONVECTION IN THE OUTER CORE CREATE EARTH’S MAGNETIC FIELD?

WHY DO WE NEED A MAGNETIC SHEILD?
