The hotspots are regions, where the plumes of magma are present just below the lithosphere. The plume of the magma is the particles of the volcano and the gases, which is erupted during the volcanic eruption. It is generated by the fragmentation of the magma. Once, it reaches the lithosphere, it get spreaded laterally.
The plumes at the hotspots are present just below the tectonic plates, a high temperature r heat and the low pressure causes the rocks present in the lithosphere to melt resulting in volcanic eruption. At hotspot, the melting of rock takes time, sometimes it is very slow, due to the presence of various tectonic plates. Hence, the plumes can remain stationary for a very long period of time without erupting.
So, the first blank can be filled with Lithosphere and the second blank can be filled with Stationary.
Answer:
85x2=170
Explanation:
the number of individuals must be multiplied by 2 since there are 2alleles for every individuals
Answer:
Ecological succession can defined as the long term progression of the biological community that takes place in an area.
It includes three steps:
Primary succession: Primary succession can be defined as the area which was devoid of life and now organism colonize there.The first organism to grow there are mosses, algae, et cetera.
Secondary Succession: Secondary succession can be defined as the area where established community is replaced by a different types of animals and plants.
Intermediate stage: The stage which is continuously developing by the never ending growth of plants and animals there.
Climax community: The final and stable community of plants and animal restricted in that area only.
