A "tool" is defined as "an instrument or device that is held by the hands and used to perform a particular task or function." Think about the tools you have used so far today. What is the most primitive tool you have used today and why? What is the most advanced tool you have used and why? *

Explanation:

The most primitive tool I used today was the hammer. The hammer is age long in the history of household tools. It is used to hit in nails into walls or woods.

The most advanced tool I have used today is the mobile phone. This is a tool of the 21st century which makes communication easier and faster.

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.
