The contractile vacuole is an organelle found in paramecia, a group of unicellular organisms. contractile vacuole pump out fresh water that accumulates in the organisms by osmosis. explain how this is an example of the way paramecia maintain homeostasis?

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.

yes it is   dangerous
