[RT] Violent, head-to-head crash between Earth and another planet created the moon - Page 3

post #21 of 72
I thought this was a pretty well known theory... it is also how the earth got its tilt so we got our 4 seasons in different parts of the hemisphere during its orbit around the sun. biggrin.gifthumb.gif

Umm the Moon is an giant egg with a Space Dragon inside. Didn't you guy's see the Dr. Who episode?

no, i am no expert - i just got done watching three seasons of "how the universe works" tongue.gif

Oh yeah, well I slept at a Holiday Inn Express last night! thumb.gif

you misunderstood my meaning, earth being a basalt planet doesn't mean it doesn't have iron.
rather i meant it has low iron content in the beginning, like <30% of it's total mass.
same goes with theia, by iron planet i meant >60% of it's total mass is iron.

Hasn't this been the prevalent theory for years of how the moon was created? Why's it suddenly news again?

i'm not understanding why you're calling the earth as a basalt planet. from my understanding basalt is cooled lava from the mantle, not the core. so it wouldn't represent the entire elemental makeup of the planet. its also found on all terrestrial planets - mercury, venus and mars.

just one thing that bothers me though, such a massive collision should've left a mark on earth, where is that said mark? the pacific ring of fire?

There doesn't have to be a mark. The assumption is that it turned earth into a molten ball of lava once again, which would take time to cool down and you'd start off with a new blue marble once again. Although it wasn't very blue back then. More like Mars, or Venus. We don't know for sure.

because earth's composition is mostly made up of what basalt is made up off, silica and other elements.

where basalt comes from is only a small part of the earth.
PLATE MOTION, MANTLE CONVECTION, AND MAGMA GENERATION
Quote:
Tectonic plates are composed of lithosphere, the rigid outer portion of the earth. With a thickness of about 100 km, the lithosphere is composed of an upper layer of crust (~7 km thick under the oceans, and ~35 km thick under the continents) and a lower, denser layer of the earth's upper mantle. The lithosphere is underlain by the asthenosphere, a hot, mobile layer of partially molten rock lying within the earth's upper mantle.

Quote:
Mafic (basaltic) magmas are generated directly from the mantle, either within the asthenosphere or within the overlying mantle lithosphere.

basalt is partly crust and UPPER mantle. elements heavier than silca ,such as iron, wouldn't be that high up in the mantle (because of gravity).

the second attempt at an analogue:
it seems you're looking at the icing on a cake thinking most of the cake is made of icing. thumb.gif

try computing the volumetric area of the upper mantle compared to the volumetric area of the inner mantle and the core.

my point is that, theia is the theoretical source of such abundant iron, if the hypothesis is correct, only the inner core of early-phase earth would be mostly iron.
with the introduction of theia, the iron content is thus dramatically increased, since the assumed volume of theia is 15% of current earth's, you can imagine how much more iron had been embedded.

plus, the moon's mantle is much more iron rich than that of earth's, which hints to the part that theia's debris is highly iron rich.
