In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other. Divergent boundaries within continents initially produce rifts which eventually become rift valleys. Most active divergent plate boundaries occur between oceanic plates and exist as mid-oceanic ridges. Divergent boundaries also form volcanic islands which occur when the plates move apart to produce gaps which molten lava rises to fill.
Relative humididty is the amount of water vapour present in the air expressed as a percentage of the amount needed for saturation at the same temperature.
I have no idea what this and u will have no idea what this says cuz thas a whole different language
Answer:
An index fossil should be found in many parts of the world.
Explanation:
A is not correct because if fossils are found in one area than they will not be able to give a general picture of the world in a particular period.
B is not correct because if fossils are found in only two locations they will be able to give information for only those two places, not the rest of the world.
C is not correct because this is simply not possible, not just for the number of fossils required, but also because the majority of the rock types don't provide conditions for fossilization.
D is correct because by being found in numerous places across the world, the index fossils can give a general picture of the biodiversity, but also the climate, and living conditions in a particular time frame.
