Answer: Deep Focus
Explanation:
A Deep focus earthquakes is one that occurs deeper beneath the subduction zone called Wadati-Benioff zone having a focus greater than 300 km deep and magnitudes greater than 6, Because of these, they can only be measured using the Moment Magnitude scale which can measure earthquakes with magnitude over 10
Here there is a forceful collision of the tectonic plates as they slide over each other within the continental and oceanic plates boundaries causing the release of great energy,with extreme heat and pressure causing the rocks to flow instead of breaking and faulting of the rocks
Deep focus earthquakes are very dangerous although occurring 20 - 30 years along a fault line are responsible for the many destructive tsunamis that happen.
Answer: True
Explanation: the theory of the island biogeography equilibrium modem describes that species have to get to a certain island from somewhere else which is the immigration part and other species have to migrate from the island as they run out of resources which is the extinction part. This theory shows that as the number of immigration increases and a new place is colonized the rate of extinction of species increases because there is more competition and limited resources for these species and vice versa.
Continents and islands are examples of large landforms called LANDMASSES.<span>
