QUESTION 5 Why would the environmental degradation associated with mining be a low priority for a less-developed country? O The country relies on the export of a mineral for the majority of their foreign exchange. O The environmental impact of mining is low. O There is usually a smaller population, so that environmental consequences are of less importance. O Less-developed countries are more likely to import minerals so environmental degradation is not as important to them. Environmental degradation is usually not concern for residents of less-developed countries. QUESTION 6 Rocks are O moved from place to place O reorganized without any changes in mineral composition in the process called the rock cycle. broken down and converted to new types of rock transported as in the hydrologic cycle incorporated into living organisms QUESTION 7 Rock formed from magma extruded to the surface through volcanic vents is classified as O lava. O sedimentary. O igneous. O weathered rock. O metamorphic.Explanation / Answer
5. If a country has some reserves of mining and it is less developed, then the country relies on that mining to export them output to make some exchange and to develop the country.
6. Rocks are broken down and converted into new tyopes of rock in the process of rock cycle. Igneous rocks are broken into pieces by wind, air water and heat and froms metamorphic rocks and sedimentary rocks.
7.Igneous rock is formed when the volcanic magma enters the surface. Once the magma is cooled then it becomes hard rock and usually known as igneous rock.
