Explain the light emission by meteorite?
Which of the following events can NOT be explained by a giant impact event?
The large metallic core of Mercury
The extreme axis tilt of Uranus
The formation of the Moon
The backwards rotation of Venus
Re-order the numbers so the events occur in the correct order, with the oldest event as number 2, and
the youngest event as number 13.
2. Now at roughly 100% of present-day mass and the asteroid bombardment over, Earth begins
cooling and differentiating. As the outer layer of the Earth cools and solidifies, lighter elements
and compounds rise to the surface while the denser ones sink to the core
3. The now differentiated ice, gas, and dust of the solar accretion disc conglomerates together into
asteroids from gravity
4. "The Big Whack"
A Mars-sized protoplanet we call Theia collides with primitive Earth, adding even more energy
and mass
5. The Big Bang
6. As the early atmosphere cools, water vapor is eventually cool enough to condense into liquid
water, eventually covering the planet in an ocean
7. The debris from the collision of Earth and Theia produce a ring in orbit. This ring eventually
coalesces into the Moon, just as Earth coalesced from the solar accretion disc
8. A nebula…
