Patterns of light dancing across the sea floor?
The patterns of light dancing across the sea floor are created by the sunlight filtering through the water's surface. As waves pass over the water, the light changes in intensity and direction, producing a mesmerizing and constantly shifting display on the sea floor. This phenomenon is a beautiful example of the interplay between light, water, and movement in the underwater world.
Which was not included in the support for Harry Hesss hypothesis of sea-floor spreading?
One key piece of evidence not included in support of Harry Hess's hypothesis of sea-floor spreading was the discovery of paleomagnetic data. While Hess's theory focused on the creation of new oceanic crust at mid-ocean ridges and the recycling of crust at subduction zones, the paleomagnetic records provided insights into the historical movement of continents and the magnetic orientation of rocks, which later supported the theory of plate tectonics. Other evidence, such as the age of oceanic crust and the distribution of fossils, played a more direct role in supporting his hypothesis.
Why are magnet patterns important evidence for plate tectonics?
magnetic rocks on the ocean floor show that the Earths magnetic field has been frequently reversed forming new sea floor.
Process in which new sea floor forms as older sea floor is pulled apart?
sea-floor spreading
The patterns of iron particles found in sea floor rocks result from what?
The patterns of iron particles found in sea floor rocks result from changes in the Earth's magnetic field over time. As the molten rock solidifies into rock, the iron particles align with the Earth's magnetic field at that time, creating unique patterns that can be used to study the history of the Earth's magnetic field and plate tectonics.
How scientist date sea floor rocks?
looking at patterns
What is the primary force that causes the sea-floor to spread?
Convection currents
What in earths interior causes subduction and sea floor spreading?
Subduction and sea floor spreading are both a result of the movement of the tectonic plates.Plate Tectonics

What patterns indicate sea floor spreading is occurring?
Ridges, parallel to the axis of spreading, are formed in the ocean floor as hot lava moves up to fill the gap then cools when it comes in contact with sea water.

What in the mantle is the force that causes the plates to move slowly over the crust?
sea floor spreadong
The movement of the ocean floor on either side of a midocean ridge is best known as?
it is known as sea floor spreading. this is when the oceanic plates diverge or move apart which causes the magma from the mantle to rise forming new sea floor.
How does sea floor spreading make the continents move?
Under the oceanic crust is the layer of the earth called the mantle. This layer is moving rock that is very, very hot! As the hot material in the mantle pushes up through the crust in the sea floor, it cools and becomes new crust as it pushes out (spreads) the sea floor. This movement in the plates causes other plates (continental and oceanic) to move as well. This is how sea floor spreading causes continents to move.
How do scientist date seafloor rocks?
Scientists date sea-floor rocks by looking at patterns in the rocks, including magnetic patterns, and by looking at the geomagnetic reversal time scale.
What cause a new sea floor to be created and how is it created?
Sea floor spreading causes this. As the floor spreads apart new magma is being pushed up through the ridge from the mantle through convection currents. It's like a recycling system.
Why are magnet patterns important evidence for plate tectonics?
magnetic rocks on the ocean floor show that the Earths magnetic field has been frequently reversed forming new sea floor.
