<span>The earth contains a huge amount of liquid or hot rock at a relatively short distance from the surface. Some of it is welling up now at various points in the world. Hot springs are the result of water seeping into the heated rocks and coming back up hot. In a geothermal power plant water is piped down to the hot area and the returning boiling water is used to produce electricity. It is a fact that lava up welling in the mid-Atlantic is moving Europe and America apart. That is a large amount of geothermal energy at work.</span>
Conflict can arise when people have conflicting goals. It can also arise when power is being manipulated and rules and regulations are not being followed.
Conflicts thus are a clash of interests such as personal motives, racial and political and may be national or international, etc. Hence all the above is correct.
Terracing here can be described as a process of carving or cutting out flat surface areas from slopes like hills, mountains for farming purposes. This helps to prevent soil erosion and flooding. It also helps to retain soil moisture.
