Answer:
Hotspot
Explanation:
Volcanoes can form in three different places: a convergent boundary, a divergent boundary, or a hot spot.
-At a convergent plate boundary, two plates collide and form a subduction zone. In the subduction zone, the denser, heavier plate goes below the more buoyant plate. The plate that goes under is subjected to immense heat and pressure and melts to form magma. This magma is less dense than the surrounding solid rock and rises to the surface through cracks in the plates to form a volcano.
- Volcanoes will form along divergent plate boundaries. A divergent boundary is when the plates move apart from each other. When the plates part, magma from under either plate rises and forms a volcano.
-A hotspot is the third place a volcano can form. This particular type is the least common. Hot spots are when thermal plumes from deep in the Earth rises. This heat, combined with the lower pressure at the bottom of the lithosphere, causes magma to form. The magma, as we discussed, is less dense than the surrounding solid crust and rises to the surface through cracks and channels and then erupts at the surface to form a volcano.
Answer:
40
Explanation:
given
product of two numbers =160
hcf =4 we know that
hcf*LCM=product of the numbers
LCM*4=160
LCM=160/4
LCM=40
When there is heavy competition between two species these results may surface. First, even if there is just a little advantage of one species, the tendency is the best competitors will dominate the other. This may lead to the extinction of the weaker species. Another result is, competition may cause the traits of the competing species to evolve. This result is called character displacement. This is what happens when for instance the species live in the same area and have the same and common niche; the characteristics of the species evolve in order for them to minimize niche overlap. This is also for them not to have competitive exclusion. To add to that, when there is heavy competition, the finite resources will not be enough for all competitors who have all access to the resources. This may lead to very low survival rates.
