Which boundary type is associated with lateral slippage as occurs at the San Andreas Fault?
The San Andreas Fault is a continental transform fault that extends roughly 1,200 kilometers (750 mi) through California.
It forms the tectonic boundary between the Pacific Plate and the North American Plate, and its motion is right-lateral strike-slip (horizontal).
How long ago did the Atlantic start to form as Pangaea started to rift apart?
about 200 million years ago
In which location in the United States would you expect to see terranes?
Terranes on the west coast of North America. The map to the right (from the United States Geological Survey) shows some of the terranes on the western coast of North America, where they have been particularly well studied.
Which boundary is seafloor destroyed?
Seafloor spreading is when the sea floor spreads apart. This occurs at Divergent Boundaries. At which type of boundary is seafloor destroyed? The seafloor is destroyed at a COnvergent Boundary.
Which feature forms at a divergent boundary?
Most divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges. While the process of forming these mountain ranges is volcanic, volcanoes and earthquakes along oceanic spreading ridges are not as violent as they are at convergent plate boundaries.
Which location is the result of oceanic continental convergence?
Ocean-Continent Convergence. When oceanic crust converges with continental crust, the denser oceanic plate plunges beneath the continental plate. This process, called subduction, occurs at the oceanic trenches. The entire region is known as a subduction zone.
Why is the Atlantic Ocean expanding?
Atlantic ocean is expanding due to formation of new crust at the mid-Atlantic ridge and westward motion of the North American Plate. Further Eurasian Plate is moving eastward and sliding over Pacific Plate and minor plates sinking in the Pacific ocean.
What was the Atlantic Ocean like 200 million years ago?
The supercontinent known as Pangea existed during the late Paleozoic and early Mesozoic eras and began to rift around 200 million years ago. Pangea had three major phases of breakup. The first major phase began in the Early-Middle Jurassic, taking place between North America and Africa.
What is the age of the oldest rocks in the Atlantic Ocean?
200 million years
Which is formed on top of earth’s crust?
The crust and the upper layer of the mantle together make up a zone of rigid, brittle rock called the Lithosphere . The layer below the rigid lithosphere is a zone of asphalt-like consistancy called the Asthenosphere . The asthenosphere is the part of the mantle that flows and moves the plates of the Earth.
How continental rifting may lead to changes in plants and animals?
how may continental rifting influence the evolution of plants and animals? it can break apart their habitat and loose their land. A measure of how easily a material can be twisted, bended, and or broken.
What is terrane accretion?
A terrane in geology, in full a tectonostratigraphic terrane, is a fragment of crustal material formed on, or broken off from, one tectonic plate and accreted or “sutured” to crust lying on another plate. The suture zone between a terrane and the crust it attaches to is usually identifiable as a fault.
