Causes of floods Flood is overflow of the huge amount of water onto the normally dry land. Flood occurs when the overflowing water submerges land and causes deluge.

erosion. And as land loses its fertile soil‚ agricultural producers move on‚ clear more forest and continue the cycle of soil loss. Overgrazing The conversion of natural ecosystems to pasture land doesn’t damage the land initially as much as crop production‚ but this change in usage can lead to high rates of erosion and loss of topsoil and nutrients. Overgrazing can reduce ground cover‚ enabling erosion and compaction of the land by wind and rain.. This reduces the ability for plants to grow and

greediness rather than actually protect people from natural calamities as they claimed to have doing (Wright‚ p 70). The enormous wealth of the priests also promoted clashes with the mountain and desert folk. On the other hand‚ deforestation due to overgrazing and ploughing of fields caused the frequent floods in Mesopotamia to have a larger than normal effect. Woodlands at first used to absorb most of the rain water but due to deforestation‚ the soaking up of the water did not work (Wright‚ p 74). The

Corinne N Bryant May 2‚ 2013 University of Phoenix The lives of the organisms in the desert require a substantial amount of survival skills. The temperature in a desert biome is always very high and it does not rain very often so it is also extremely dry. Any organisms that live in the desert must be able to adapt to these conditions in order to live. For example‚ one organism that can be found in the desert is cacti. Cacti roots are closer to the surface than other plants so it is able
