<span>True. When oxygen increases, an increase in aerobic organisms also occurs. The increase in atmospheric oxygen favors the appearance of these organisms. The increase in atmospheric oxygen favors the appearance of aerobic organisms. There are several consequences in the evolution of organisms that could use oxygen as the plants that are the main factories of oxygen in the earth and depend on atmospheric CO2 (photosynthesis).</span>
They could then find out why the rocks and earth is that way and why the area looks like it does in the present and past
Answer:
Option (1)
Explanation:
Hotspots are the regions where the magma rises towards the surface due to the presence of large mantle plumes. The force exerted by the magma here is very high. When the lithospheric plates move over these regions, the magma comes out to the surface forming volcanoes. And as the plates move away from the region of hotspot they eventually cool. These hots spots are fixed at a place. There are numerous hotspots on earth. for example, the Hawaiin island chain, below which there are regions of hotspots.
Thus, the hotspot regions are not associated with the plate boundaries.
Hence, the correct answer is option (1).
D. Near the centre of a large plate
(not 100% sure but i think it is correct)
