How do rocks along the central valley of the mid-ocean ridge provide evidence of sea- floor spreading?
they can leave marks to prove that they have existed
How does ice transport materials?
Through Plucking, when melt water freezes in the cracks of a mountain, and plucks out the loose rocks, and also abrasion, when the looses rocks scrape along the valley floor, to pick up even more till, and create striations, which are marks left on the valley floor. Ice also picks up even more rocks through landslides, or rocks falling over the hanging valley, (which is a steep drop created after interlocking spurs have been truncated, by the glacier cutting through them.) The rocks and other natural debris then is frozen, by the melt water, and is transported as the ice moves, in a glacial retreat, or advance.
How do rocks along the central valley of the mid ocean ridge provide evidence for sea floor spreading?
because the scientists found that the farther the rocks the older the rocks were. so the youngest rocks were found near the mid-ocean ridge. this showed that sea-floor spreading took place. +++ The primary evidence is "magnetic striping": remnant magnetising by the Earth's magnetic field of the iron compounds in the basalt forming the ocean floor. The magnetic traces are parallel to the spreading-ridges, and their polarity reflect the field's periodic reversal. The further from the ridge, the older the stripes. The rock is imprinted with the magnetism as it cools below a certain point in being eruped along the ridge.
A glacier slowly moves down hill due to gravity as it flows it pickeds up rocks and soil and it carries it along this diging out of the earth forms?
It forms a Valley.
Where does the new rocks form on the sea floor?
Forms by lava from volcanoes on the sea floor

What kind of rocks are in Death Valley?
Metamorphic, along with volcanic and plutonic igneous rocks.
How was the central valley formed?
The Central Valley in California was formed by a combination of geologic processes, including tectonic plate movement, faulting, and erosion. Over millions of years, the valley was shaped by the movement of the Pacific and North American plates along the San Andreas Fault system, and further sculpted by the flow of rivers and glaciers. The valley continues to be shaped by ongoing geologic processes.

Is it true that the magnetism of the rocks along the ocean floor is consistent in that there is no reversal of polarity?
The rocks of the ocean floor are not consistent and do show past reversal of polarity. The statement in the question is false.
