When you go down below the surface of the Earth, the gravity will initially INCREASE. This is because Earth's density is not uniform - there is more mass concentrated closer to the center, than in the case of a sphere of uniform density. If Earth were a sphere of uniform density, the gravity would get less, once you go below the surface - because some of Earth's material would pull you upward.In any case, if you go further down, eventually the force of gravity will become less.
When the gravity increases (as it does initially), the period will become shorter.

Is earths surface in constant motion?
Yes, relative to any observer not attached to the earth's surface.
What occurs when objects free fall near the Earths surface constant acceleration?
Yes, exactly. Free fall results in constant acceleration.
Is gravity a variable?
Gravity is a constant not a variable. (stays constant at 9.8ms/s in earths atmosphere)
What is featured sculpted on earths surface by internal or external forces?
buthole
What are some examples of constant motion?
Light, Earths orbit, flowing river
What is The constant recycling of water from the earths surface?
the water cycle
Is earths surface in constant motion?
Yes, relative to any observer not attached to the earth's surface.
What type of pendulum used to demonstrate the earths rotation?
Foucault's Pendulum
What is the constant movement of water between the atmosphere and earths surface called?
water cycle
What occurs when objects free fall near the Earths surface constant acceleration?
Yes, exactly. Free fall results in constant acceleration.
While an object near the earths surface is in free fall its mass increases?
No. The mass is constant. Until it hits.
