it provides evidence of the EARTH's rotation.
Evidence that is provided to the courts.
evidence that supports the conjecture that the Earth is rotating
At the extremities of the pendulum's swing, the sand leaving the bob could exert a force on the bob. Provided that this force is negligible and also, provided the mass of the bob (with or without the sand) is large compared with the rest of the pendulum, the time period should not be affected.
For earthbound investigators, the Foucault pendulum provides a nice proof.
evidence that supports the conjecture that the Earth is rotating
No, a torsional pendulum works with the restoring force provided by the elasticity of the support rod, or (in clocks and watches) by the spring on the balance-wheel.

What two types of rock provided evidence of the composition of Earth'sinterior
Yes, perhaps one of the simplest and best evidences.
It provides evidence of the Earth's rotation on its axis.
