Meiosis contributes to genetic variation due to which of the point
following characteristics of the process?

answer:

genetic variation is increased by meiosis. during fertilisation, 1 gamete from each parent combines to form a zygote. because of recombination and independent assortment in meiosis, each gamete contains a different set of dna. this produces a unique combination of genes in the resulting zygote.

explanation:

plate tectonics and volcanic euptions

over time, plate tectonic processes cause continents to move to different positions on the globe.

for example, britain was near to the equator 300 million years ago, and therefore was hotter than it is today. for further details look at our climate through time poster or online map.

the movement of the plates also causes volcanoes and mountains to form and these too can contribute to a change in climate.

mountain ranges formed by plate tectonics. large mountain chains can influence the circulation of air around the globe, and consequently influence the climate.   warm air might be deflected somewhere cooler by the mountains.
