plate boundaries

Plate boundaries have three different kinds: divergent boundaries, convergent boundaries and transform boundaries. A different type of plate movement occurs with each type of boundary.
I will explain what happens with these three kinds of plate boundaries. When two plates move apart, or diverge, it is called divergent boundaries. When two plates come together, or converge, it is called convergent boundaries. A transform boundary happens when two plates slip past each other, moving in opposite directions.
Well when divergent boundary start moving, they form a valley. When convergent boundaries start moving, they form a mountain range. When transform boundaries start moving, they slide side by side.

IS GLOBAL WARMING GOING TO KILL OUR CHILDRENS ?

Global warming happens because of pollution, smoke, desforastion or burning forests. These things destroy the ozone layer. As a result, the polarcaps will melt, the cities will flood, and animals and plants will die.
But we can prevent this by planting trees, reducing CO2, recycling, and using altarnative fuels. And we can prevent global warming together, our world will be clenear and we will live bettler.
