Lithosphere

Our Earth's Lithosphere

During our discussion in Environmental Engineering, I was recalled about the land portion of our earth.  30 percent of the Earth is composed of land. Land is very important to us, humans, because this serves as the foundation of our shelter. Our Earth composed of three main layers, the core or the inner layer, the mantle and the crust which includes the continents and the ocean floor.  Our Earth’s outer layer is broken into pieces and this is called tectonic plates.

From past to present, we experience and some witness volcanic eruptions earthquakes, and some are tsunamis. We know that this happens because this is a natural occurring phenomenon in our planet. Our activity interfered our nature, which cause a natural disaster or make the effects far worse. One example is, we do not cause earthquakes that are generated by tectonic movement and seismic activity, but underground mining can result instability that causes earthquakes.

We, humans are not just the cause of the rise in natural disasters but we also played the major role in destroying our environment and are continuing to do so. Our environment is being damaged more by us, humans, than by natural disasters. We can give back to Mother Nature what we have taken from her.  WE act NOW or pay the price soon.
