Terrestrial
Planets Ended up Rocky
-
Why did some protoplanets
turn into terrestrial planets, others into Jovian planets?
-
Protoplanets close to protosun
were hotter
-
Materials with low melting
points remained in gas phase (phases of matter primer)
-
Water (H2O)
-
Methane (CH4)
-
Ammonia (NH3)
-
Gasses did not stick to early
protoplanets (too small, gravity too weak)
-
Materials with high melting
points were solid and stayed behind
-
rock
-
iron
-
silicates (sand)
