They allow magma to burst between cracks, and they cause blocks of rock to seperate and form new plates.
The plague was spread because of the poor hygeine back in that time
Answer:
Marine fossils found on landmasses.
Explanation:
Earth is an active planet, with tectonic plates that constantly move across the surface and cause changes in the distribution of physical features. The changes, in a most basic manner, can be seen in the creation of new continental masses and new ocean basins, and the destruction of continental masses and ocean basins.
The oceans we see at present have not been around forever, but they formed where plates have started to separate, while in meantime the preexisting oceans have suffered decline and eventual destruction because of it. An excellent example of where there were oceans in the past are the marine fossils. In many parts of the world that now are part of the continents, there is a huge number of marine fossils, even on mountain ranges like the Himalayas and Andes. This proves that in the past, these landmasses were part of an ocean, but because of uplift they have risen up and became part of the landmasses.
Answer:
To the east, the North American plate shares the Mid-Atlantic Ridge with the Eurasian plate. This divergent margin, offset throughout by transform faults, began spreading approximately 180 Ma ago, opening the North Atlantic Ocean. Evidence of Mesozoic juvenile crust formation in New England can be correlated with the event.
Explanation:
The San Andreas transform boundary between the Pacific and North American plate originates from the shallow, oblique subduction by the North American plate of the Monterey microplate
The Monterey-Pacific ridge stopped spreading and Monterey accreted to the Pacific plate. As a result, the Pacific plate’s motion with respect to the North American rotated, transforming a network of shallow faults into dextral transform faults
