Yes
No. The rock cools down as it moves away and sinks deeper.
Seafloor spreading at midoceanic ridges.
Harry hess' hypothesis was hot/less dense material rises up the Earth's crust toward the mid-ocean ridges. When the seafloor breaks apart, magma is forced upward and through the cracks. It cools, and becomes a new seafloor. When it moves away from the mid-ocean ridge, it becomes denser and sinks. This helps form ridges.

Age of seafloor rock and sediment increases with distance from the oceanic ridges.

Mid-oceanic ridges
The youngest seafloor rocks are found in the rift valleys of the mid ocean ridges. At the mid-oceanic ridges there is tectonic movement bringing new magma to the surface.
