The Features of a Familiar Planet

The glacial pace of these global changes
mostly hides them from our eyes,
but still, the features slowly shift.
Tectonic plates drift, collide
and uplift the surface like bones.
Wind, rain, and rivers erode,
carving channels down through the skin.
Gravity sags at the furrowed brows, cheeks, and chin.
And our terraforming efforts, too,
like the repeated formation of expressions
across the geologic epochs,
bring on changes –
now pinching up these frowning ridges,
now spreading out these lines of laughter.

What stories will be mapped out in the end
over the face of this, my earth?
