Answer:
Explanation:
At constructive margins such the mid oceanic ridge where new magma are brought to the surface, evidences abounds to support the theory of continental drift through paleomaganetism.
Continental drift is simply the moving of the land masses on earth from their original positions.
There are certain magnetic minerals in rocks that are able to record the prevailing magnetic conditions in a particular terrane. In a hot magma, at the oceanic ridge for example, these minerals align to the magnetic direction at work during the period when they are cooling. As new materials upwells, the cool layer shifts away from the margin each bearing the paleomagnetic record.
Therefore, through a series of reversals and normality in the magnetic direction, one can deduce that the continents actually moves.
<u>Answer:</u> transitional
<em>Gerobatrachus hottoni mostly like to be transitional fossil.</em>
<u>Explanation:</u>
<em>Gerobatrachus refers to an extinct genus of amphibamid temnospondyl, which thrived in the initial Permian, that is, about 290 Mya</em>, in the region, which is now known as Baylor County, Texas.
The transitional form of fossils is those that <em>demonstrate the intermediate form between the two distinct living species, </em>it could be in a form of an ancestor and its descendants.
It has been believed that the reptiles creatures as frog have evolved from the <em>previous ancestor of primitive amphibian tetrapod subclass known as Temnospondyl. </em>
