is weathering responsible for bio-diversity on the earth?

Answer 1

Weathering is the wearing away of earth's landforms by chemical (water reacts with the lime in limestone to create cavern systems) or mechanical (tree roots lift & break sidewalks) means.
Jayme C's point is well-taken in the sense that weathering can create new niches for various lifeforms to inhabit/exploit. But I don't think that means that weathering is responsible for bio-diversity, although it might be a partial answer.
In my opinion, bio-diversity is much too complex to have a single cause. Geology, hydrology, weather, plate tectonics ... all these and more taken together are "responsible for" the diversity we see around us.

Answer 2

Weathering is indeed a major factor on the bio-diversity that abounds. As you know, weathering creates new and wonderful hiding places as well invites new guests to the area which in turn creates a new and abundant food source

Answer 3

I'm sure
cells must withstand the test of time long enough to procreate. The weather differs from area to area and seasonal changes as well. cellular diversity is the key to survival.

Answer 4

Nope, it's the inverse.
