According to Wegener's theory, why were tropical plant fossils found in Arctic islands? Plants were more adaptable in the past.
O The poles of Earth were warmer in the past.
O Arctic islands were closer to the equator in the past.
O Land movements warmed the landmasses in the past.

C. Arctic islands were closer to the equator in the past.

Explanation:  Wegener while studying this drifting observed several fossils and rocks that were correct. According to the findings of the theory of Continental Drift, the reason that the tropical plant fossils were found on the Arctic Islands was because Arctic islands were close to the equator

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.

they are both synthetic elements

explanation:
