Cells in a hypertonic solution tend to:
shrink due to water loss
swell due to water gain
stay the same size due to water moving into and out of the cell at the same rate
none of the above

Shrink due to water loss

Explanation:

A hypertonic solution has more osmolarity than the cell. This causes the water inside the cell to go out since the osmolarities tend to equalize. And the cell does not allow the passage of other substances except water. Therefore the water will come out and the cell will shrink.  

In a hypotonic solution, the water will enter into the cell and in an isotonic solution the water will be moving into and out of the cell at the same rate.

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.
