What is the hypothesis that continents have moved slowly away from there current locations?
It was called "Continental Drift" and was promptly (and rightly) dismissed as it proposed that the Continents were somehow plowing through the solid rock of the Oceanic crust, like ships through the liquid water of the ocean. It took observations made by the US Navy during the 1950s (and kept classified secrets for many years), including volcanic activity of the midocean ridges, magnetic reversals in the Oceanic crust that were symmetric about the midocean ridges, and very deep ocean trenches. These showed that large moving plates existed in the earth's crust that transported both the Continents and sections of Oceanic crust in various directions. Ultimately this provided a workable mechanism that replaced the rejected "Continental Drift" hypothesis with the Theory of Plate Tectonics.
How do ocean ridges and deep-sea trenches support the theory of sea floor spreading?
Sea Floor spreading has to do with the crust forming at ocean ridges and being destroyed at deep sea trenches.
How do earths magnetic pole reversals provide evidence for tectonics?
rocks get older as you move away from ocean ridges
Where is new crust being created?
In oceanic ridges and continental rift zones.
How do earths magnetic pole reversals provide evidence for plate tectonics?
Magnetic stripes can be seen as you move away from ocean ridges.
How do mid ocean ridges support the idea of continental drift and the theory of plate tectonics?
New crust forms at mid-ocean ridges.
Where do midocean ridges intersect the landmasses?
Midocean ridges are areas where continents broke apart. Midocean ridges are closest to the landmasses in younger oceans. One example where a midocean ridge intersected a landmass is the Arabian sea, which was formed by the pulling apart of the Arabian Peninsula and Africa.
How was plate tectonics proven through continental drift?
The creation of crust at the mid-oceanic ridges.
Where are the midocean ridges offset the most by faults?
At transform faults or transform zones.
What are some landforms that support the plate tectonics theory?
Earthquakes, volcanoes, canyons, mid-ocean ridges, mountain ranges and so on and the results of plate tectonics.

Sea Floor spreading has to do with the crust forming at ocean ridges and being destroyed at deep sea trenches.
Is the Mid-Oceanic Ridge in the middle of the Atlantic Ocean?
One of the midocean ridges is, but others are in other oceans, seas, and bays.
Do Ocean sediments become younger or older away from midocean ridges?
Older, as it moves away from the mid-ocean ridge the sediment gets thicker and older
Why is theory of continental drift widely accepted today?
The theory of continental is not accepted as it is been disproved, but it was replaced by the theory plate tectonics. This theory accepted because of may factors including the discovery of mid-ocean ridges, subduction zones, and the tracking of plates via GPS and other means.
What are the 3 type of earthquakes?
(1)midocean spreading ridges, (2) subduction zones, and (3) transform faults.Normal fault, Reverse fault, and strike-slip fault
What is the process by which plate tectonics produces new oceanic lithosphere at ocean ridges called?
Seafloor Spreading.
