Scientists recently discovered that three different types of squid, a marine animal, previously thought to be
three different species, were actually all members of one species. Their earlier ideas were based on using
squid carcasses (dead bodies). The new, more accepted classification is most probably based on an analysis of
(1) a greater number of squid carcasses
(2) the feeding habits of the three different species
(3) a number of newly found squid fossils
(4) the DNA present in the cells of squid

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.

the answer is false?
