What are the rocks close to a mid ocean ridge younger than the ones that are farther away?
no
How do magnetic stripes show the history of Earth's magnetic field?
as you move away from an ocean ridge the rocks get older
What happens when you move roks away from the ocan ridge?
They increase in age and density, and decrease in temperature.
How did scientists discover that rocks farther away from the mid ocean ridge were older than the ones closer to the mid ocean ridge?
I don't believe that is possible to figure out

as you move away from an ocean ridge the rocks get older
How did scientist discover that rocks farther away from the mid ocean ridge were older that those near it?
i never know

As you move away from an ocean ridge, the rocks get older.

What would you expect to find if you measured the temperatures of rocks on the ocean floor at various distances from a mid-ocean ridge?
If one was measuring the temperatures of rocks on the seafloor, the hottest rocks would be located nearest to a mid ocean ridge. This is the location where the hot magma from the asthenosphere rises and is situated on either side of the ridge. The farther away the seafloor is from the central area of heat, the colder it is. This pattern is identical on both sides of a mid ocean ridge. However, if rocks are located near subduction zones or hot spots, they too would be hotter than the majority of the seafloor.
Why does the ocean floor spread apart at the ridge?
Because as tectonic plates move away from each other, the ocean floor spreads apart and fills the gap.
What is the relationship between the age of rocks on the ocean floor and the distance from the Mid-Atlantic ridge?
The farther away the rocks are, the older they are. When the lava bubbles up from the ridge, the tectonic plates move outward. As the process repeates itself and new lava comes up, the rocks are pushed farther and father away. As a result, the closest rocks are the newest, and the farthest rocks are the oldest!
Explain the process by which new sea floor forms at mid ocean ridges?
as it spread away from a mid-ocean ridge, the sea floor carries with it a record or magnetic reversals. i hope this answer would be correct :) also, when the magma rises through fractures in the sea floor at the mid-ocean ridge, the magma cools and forms new rocks. this new rock takes place of the old rock and the old rock gets pulled away.
