13 Cain said to the LORD, "My punishment is too great to bear!
14 "Behold, You have driven me this day from the face of the ground; and from Your face I will be hidden, and I will be a vagrant and a wanderer on the earth, and whoever finds me will kill me."
Cain is driven from the 'face of the ground' and against which punishment he even protests as being harsh because to be 'driven/cast away' is a strong term.
Eg Genesis 3:24
So he drove out the man; and he placed at the east of the garden of Eden Cherubims, and a flaming sword which turned every way, to keep the way of the tree of life.
But Cain still 'wanders' in the 'earth', to imply that the 'face of the ground' and the 'earth' mean differently, even he is spotted later building a city.
How then does 'face of the ground' and 'earth' differ in the verse?
