Eli5: When the sun heats up a rock – what is actually happening to the rock?

Do the atoms of the rock vibrate faster from the suns rays or is the solar heat being trapped in the rock?

Yes to both. The heat energy makes the atoms vibrate faster, and they store this vibrational energy, which makes the rock warmer for an extended period of time.

Rocks are more efficient at receiving energy from the sun than transmitting it to the atmosphere.

heat *is* atoms vibrating. The atoms of the rock absorb photons and the energy of the photons are converted into kinetic energy of the atoms.
