How could the collision of convergent tectonic plates affect the biosphere?

When there are two continental plates converging, the crust would squished together and folding to form mountains. This collision will have an effect in the biosphere by creating volcanoes and earthquakes. The mountains affect the earth's geosystem when it diverts the water ways affecting Hydrosphere. This then will affect biosphere when water ways are diverted as it is where animals as well as the people get water.

That is false the sun’s core does not fusion
