Seafloor Spreading

The below model demonstrates the movement of energy and matter under the Earth's surface. Use this diagram to answer the following questions.
NGSS Phenomena: Two oceanic plates, with arrows that show they're moving away from each other. There's a green circle in between the two plates. Under the plates it's red, with two circles of arrows, showing movement that goes upwards in the direction of where the two plates meet.

1. Which land feature is shown circled (green circle) on the image below?

2. What happens to the age of the seafloor as it moves away from the center (green circle)?
