Building up and breaking Down

In this new 4 bimester we start with the topic Building up and breaking Down . In this topic i learn about why mountains look like they do , maybe in movies you have seen perfect mountains like the ones you draw but there really dont look like that , they look like a bad cutten top this because of rocks expansion and breaking . I also learn waht is erosion and weathering and the difference between them , the difference is that weathering is the breaking down of rocks into smallers pieces by natural process . And erosion is The picking up and removal of rock particles .   

I also learn the diferent type of  mountains that are fold mountain , fault block mountain . I learn about all the horizon a , b , and c also the bed rock , how they look like and how they form , also how  other names scientist put to them .And the part of this topic that i think was thw most important was that i learn why we have to conserve the soil .

In this pictures you can found the horizons and it other names .
