Answer:</h2>
1. <u>Minerals</u>
2. <u>Geological</u>
3. <u>Indefinitely</u>
4. <u>Pressure</u>
<h2>
Explanation:</h2>
1. The minerals play a wide role in industrial and agricultural developments. In industries, the minerals are used as raw materials at the same time in agriculture, it is helps in growing plant growth as fertilizers and nutrients.
2. The geological activity includes movement of earth plates under the earth's surface which is mainly due to presence of heat deep inside the earth.
3. There are huge amount of minerals in this earth, but everything is need to be used in a very economical way, without wasting.
4. The pressure and temperature is need to favorable to form the minerals.
A common rock type found within oceanic crust is called basalt rocks. It is dark just like an igneous rock and it is basically a type of lava from a volcano.
A. Used fire to do controlled burns
The result of controlled burns were highly beneficial to both the Aborigines and the environment. The burnt remains of the burns were very fertile and encouraged the growth of new vegetation that would not have been able to flourish if the older growth had not been removed. The removal of old vegetation also resulted in a low chance of wild fires. Further more new vegetation was able to attract wildlife to graze, making hunting easier.
The concept of controlled burns is still used today and was/is also practiced by First Nations in North America.
Answer:
Karst topography is formed from soluble rocks with many features that create crevices that channel or funnel the surface water into the ground and aquifers below. This can lead to contamination of the water quality in aquifers.
Explanation:
Karst topography refers to the topography formed from soluble rocks such as limestone, dolomite, and gypsum. The topography evolves as the soluble rocks are exposed to wind, sun, and precipitation that erodes the rock materials and creates crevices and the groundwater is channeled away from the surface, inhibiting the formation of lakes and reserves of water at the surface. When these sorts of rocks begin to dissolve caves and crevices and other forms of underground drainage. Five topographic features a geologist might find are solutions flutes and limestone pavement, cenotes, funnel-shaped sinkholes, and reappearing streams.
The surface hazards associated with karst topography are sinkholes as well as other topographic hazards such as subsidence and slope movements. There is a lot of surface water and groundwater interaction in a landscape with karst typography and so aquifers are susceptible to contamination from pollution and the use of fertilizers and chemicals at a higher rate than other topographies. Urban areas and areas where there is a lot of animal husbandry are especially vulnerable to aquifer contamination.
