Mammals and turtles

Explanation:

Mammals and turtles are more closely related to each other as compared to the other organisms.

Cladogram is a representation which is used to find out the closely related species. By looking into the cladogram the most recent common ancestors to mammals are reptiles.

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.
