 * This picture shows how sea floor spreading is processed; as you can see the sea floor seperates and the hot magma rises to the surface towards the ocean trenches. Its a continuous proccess of seperating layers of magma, mostly the magma that is cooled is recylcled because of the subduction of the sea floor, causing the continuous cycle. This helps geologists examine how old the layers are; basically the out layers are the oldest, and the inner layers are new and fresh.





Posting By: **Beata Surma** Source of information and image: [] [] Caption: These images above show continental drift. At around the Pennsylvanian period Europe was near the equator-but now is isn't. Scietists figured out the concept of continental drift because they had noticed that either the magnetic poles were moving or the land was, and later they realized it wasn't the magnetic poles. More evidence of the land masses moving was when it turned out that the paths for North America and Europe had quite the same paths, but were seperated a little bit. By these migration paths it was noticed that North America and Europe must have been locate next to each other but moved over time.

Peter Aziz Source: [] Caption: This picture represents the Earth’s magnetic field. When heated at a certain temperature the magnetic minerals lose their magnetism, this is also know as the curie point. They also magnetize in the direction of lines of force when cooled. Also provides the latitude. The inclination of the paleomagnetism tells you when the rock was magnetized.

Postings: **Ken Ham** Source: [] Caption: This image shows the periods of continental drift. What continental drift is the movements of continents in the Earth and the earths rotation. WHAT DOES THIS HAVE TO DO WITH THE READING ON THE EARTH'S MAGNETISM?

Posting by: **Monika Dudzik** source: http://haribrahma.wordpress.com/2009/04/ The image shows Geographic MISSING SOMETHING HERE and Magnetic Fields of Earth. The arrows show the flow of magnetic movement.\

Posting by: **Jasmin Markicic** source : [] Caption: The dotted lines at the centre of the diagram represent the processes in the earth's core that produce a magnetic field The arrows represent invisible lines of force, known as magnetic field lines. the green line represenrts the geographic north and south pole and the yellow line represenets the magnetic north and south pole.

The Geographic poles and the magnetic poles align closely but are not the same. The Geographic poles are where the Earth's rotational axis intersects the surface. WHAT DOES SIDE B SHOW?

  = Source of the image and information: [|computerkiddoswiki.pbworks.com/ Continental-Drift-]= Caption- As you can see the image of Sea-floor spreading in which the mid-oceanic ridge where a divergent boundary is causing two oceanic plates to move away from one another resulting in spreading of sea floor. AS the plates move apart, new material wells up and cools onto the edge of the plates. As a result, two layers are formed : the oldest at the bottom and the youngest at the top.

Posting by **Nikko Andriotis** [] Caption: This picture illustrates the Earth's magnetic field and which way the forces a pulling. WHAT DOES THIS MEAN?

[] Caption: This picture MISSING IMAGE shows the continental drift through different periods of time. Posting By: Camelia Hammad Source: http://eideard.wordpress.com/2008/09/27/lava-flows-offer-new-information-on-earths-magnetic-field-reversals/ Caption: This is a picture of the earths magnetic fields, and how they go from the south of the earth to the north.

Posting by: **Michaela Laws** source: @http://www.ssec.honeywell.com/magnetic/magpics/earth.gif The image shows the Earth's Magnetic fields (which are actually invisible) and how they travel from the south pole to the north.

This picture is a basic depiction of the Earth and its magnetic fields. The magnetic field here shows A North and south pole. The magnetic field however is mostly caused by electic currents from the liquid outer core. Posted by Erik Guevara.

Caption: This picture shows the Earth's magnetic field, its showing which way it is pulling. So what does this mean? Great question! It means the magnets create a vector field the magnetic field, at every point in the space around the field.

posted by: jessica cholewa caption: above is a picture of the magnetic field around earth [left] and also aroung the magnet [right]. the magnetic field starts at the south pole and works it's way up to the north pole. for some reason the earth's magnetic pull is always pulled up north...so the earth if similar to a magnet because they basically both have the same magnetic fields. picture is from this website: []

Caption: Above is a picture of the Earth's magnetic field. The m ain magnetic field is produced by electrical currents in outer core, and the e xternal magnetic field is produced by electrical currents in ionosphere.
