The invasive European buckthorn invades a local forest preserve. Initially, the population of buckthorn rapidly increases, and then it begins to level off. This pattern of population growth most closely resembles Logistic growth. When the individuals of same specie lives in a region as a group, then they will be called as the population of that region. The rate of population growth usually increases in the area where all the resources like food and water are in abundance for its people. However, when these resources comes to an end or reduce then one can observe the decrease in population as well. When the individuals increases but the growth rate of population reduces, this phenomenon is called Logistic growth.

a mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. this uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.a geomagnetic reversal is a change in a planet's magnetic field such that the positions of magnetic north and magnetic south are interchanged.
