Reproductive variation is central to evolution. All else in evolutionary theory follows directly or indirectly from the fact that organisms reproduce with variation.
Natural Selection
...The driving force of weather is the sun.
No. It is merely one of many parameters that influence the direction of evolution, and can actually be a driving force in evolution. For example, the rise of warm-blooded mammals as a result of colder climate (a clear period of limited food resources) caused by climatic or astronomical phenomena, like the impact of a meteor.
The main driving mechanism of evolution is natural selection. Though genetic drigt and gene flow can also cause evolution.

Natural Selection
To Darwin, the central concept of organic evolution was natural selection. He proposed that individuals with advantageous traits are more likely to survive and reproduce, passing those traits on to their offspring, leading to changes in the characteristics of a population over time.

That there is no central idea.
Natural selection is the process of certain animals being more successful than others and thus reproducing more. It is the driving force behind evolution as we currently understand it.
The antagonist is the person or force that opposes the central character (protagonist) in a story. They create conflict and obstacles for the protagonist to overcome, driving the plot forward.
There is no central force, except that anything which does not hinder a gene's chance of reproducing will allow whatever species that gene belongs to live on. If a trait helps a species to survive, that trait will be "selected". Look at it this way, if a particular trait means that some members of a species is less likely to breed than other members, that trait will die out eventually. This could mean that lions which have shorter claws than their fellows, or cheetahs which can't run as fast as their fellows will go hungry, and be less successful in having and rearing cubs which carry their genes. That is not so much a force driving evolution as a force culling those members of a species which are "less fit" for survival than their fellows
Charles Darwin Published "On the origin of species by means of natural selection" in 1859. He was not the first to postulate evolution. His grandfather Erasmus Darwin advanced the theory of evolution 75 years earlier. Charles Darwin gave us the driving force "natural selection"
the driving force for erosion is , when bad things come out of driving that involves erosion.
Competition would be the driving force of exclusion
