What the difference between convergent and divergent?
Two paths which are convergent will come together in the distance. Two paths which are divergent will get further and further apart in the distance.
What is a process at a divergent boundary where new earth is formed?
At a divergent boundary, new earth is formed through a process called seafloor spreading. This occurs when tectonic plates move apart, allowing magma from the mantle to rise and solidify at the ocean floor, creating new crust. As the plates continue to separate, more magma emerges, further expanding the oceanic crust. This process is most commonly observed at mid-ocean ridges.
Why is some of the newest crust on earth along a divergent boundary?
The newest crust on Earth is found along divergent boundaries because these are regions where tectonic plates are moving apart. As the plates separate, magma from the mantle rises to fill the gap, solidifying to form new oceanic crust. This process is most prominently observed at mid-ocean ridges, where continuous volcanic activity generates fresh crust, making it younger than crust found further away from the boundary.
How are plate boundaries classified?
They are classified based on the vector of relative plate motion at the boundary. For example a boundary where the plates are moving away from each other is a divergent boundary, one where they are moving towards each other is a convergent boundary and one in which they are sliding past each other is a transform boundary.
What process is found at a divergent boundary will help the sedimentary rocks?
At a divergent boundary, tectonic plates move away from each other, leading to the formation of new oceanic crust through volcanic activity and magma upwelling. This process creates mid-ocean ridges where sediments can accumulate over time as the ocean floor spreads. As these sediments are deposited and compacted, they eventually form sedimentary rocks, contributing to the geological record. Additionally, the movement of plates can expose older sedimentary rocks to erosion and further sedimentation processes.
Are the earths countries moving further apart?
No the continents are.
Plate tectonics what forms along continental divergent boundaries?
Along continental divergent boundaries, rift valleys or rift zones can form as the continental plates move apart. These rift zones may be accompanied by volcanic activity and seismic events as the crust stretches and thins. Over time, if the divergence continues, a new ocean basin may form as the continents separate further.
What was an alternate theory used to dispute the theory of plate tectonics?
A proposed explanation for identical species found in divergent locations was the land bridge theory, which supposed shifting dry areas across which living things spread. The further study of rock formations (which were also identical) lent greater weight to the idea that continents were actually joined together in the past.
Why don't the present shapes of the continents fit perfectly into a super continents?
As the continents moved further apart, natural erosion of the Coastlines removed and added to the basic shape over billions of years. Much of the evidence relates to the similarities of plants and animals found on now separate continents. Geological evidence points to Antarctica was once further north and had a tropical climate!

Do continents drift slowly on earths upper mantle or earths core?
Continents drift on top of the upper mantle. The core is much further down.
What was the names of the two continents after Pangaea split?
The two continents that formed after Pangaea split were Laurasia in the north and Gondwana in the south. These two supercontinents eventually broke apart further to form the continents we have today.
