5. Myth: Mammals and plants don't belong in the same domain.

Yes, this is a myth, as mammals and plants are both eukaryotes at the end of the day, meaning that they share a multitude of common characteristics. These characteristics include a size generally larger than prokaryotes, DNA enveloped by a membrane-surrounded nucleus, membrane-bound organelles, undergoing of complex processes like cellular respiration, presence of a cytoskeleton, linear DNA with histones, DNA with introns, undergoing of mitosis/meiosis, etc.

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.

i am going to guess that it is co2.
