Question
According to one theory, this planet had an orbit close to one of two stable Lagrange points between the proto-Earth and the Sun before it was perturbed by other objects in the Solar System. For 10 points each:
[10m] Name this planet that, according to the Big Splash theory, collided with the Earth around 4.5 billion years ago, ejecting rock that became the moon.
ANSWER: Theia
[10e] Recent models of Theia’s collision with the Earth showed it would have resulted in temperatures great enough to melt this layer of the earth below the crust and above the core.
ANSWER: mantle
[10h] The Theia impact is one explanation for large provinces of dense rock in the mantle often named for imparting this quality to shear waves traveling through them.
ANSWER: low velocity [or low shear velocity; accept answers like a reduced velocity or slow or synonyms]
