Forests are crucial to the health of our planet because they

cause global warming

They provide oxygen for us to breathe, in rural areas they use it as a source of fuel;it is also used to make furniture.

sediment layers stop spreading when they reach a barrier or they run out of sedimentary material. lateral spreading is the movement of gently to steeply sloping, saturated soil deposits caused by earthquake-induced liquefaction. i hope this . : )
