How does the sodium atom bond to the chlorine atom ?

Explanation:

It is happening when a sodium atom loses an electron to a chlorine atom and because of that sodium atom is becoming a positive sodium ion and the sodium ions and chloride ions form an ionic lattice.

Sodium - Na

Chloride - Ch

Sodium and Chloride are both elements that cannot be found separately and free in nature but they are found as bonded together.

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.
