Geology
-
Inner structure of Earth
studied by seismic waves
-
deduce dense elements (like

-
Earth only planet with plate
tectonics
-
caused by convection (lava
lamp effect) in outer mantle
-
Hot spot volcanism (e.g.
Hawaii) also found on other planets like Venus and Mars
-
Magnetic field carves out
magnetosphere in solar wind
-
traps charged particles which
can cause Aurora Borealis (northern lights)
-

caused by convection (equator to poles) and rotation (east-west bands)
