The surface feature on Earth that resembles the seams on a baseball is the mid ocean ridges.
Step-by-step explanation:
The surface feature on Earth that resembles the seams on a baseball is the mid ocean ridges. These are long undersea mountain ranges formed by lava rising from Earth's mantle at plate boundaries. The movement of tectonic plates causes these ridges to form, creating a pattern similar to the seams on a baseball.
