The correct answer is A. 110GPa
Explanation:
Pressure refers to a force applied to a surface or object either by another object or factors such as the atmosphere. This is calculated considering the force applied and the area. Additionally, this factor can be measured using the unit gigapascals (GPa), which is more common in geography and related areas.
In this context, the lower mantle, which is the layer below the upper mantle has a pressure between 24GPa and 130GPa; and this is a high pressure if compared to the pressure in the surface. Thus, the estimated pressure in this zone is 110GPa because this is the only number that is between the range of pressure in this zone, while others show a higher pressure that is not found in this layer.
450000, 150000 times 3 is ezual to 450000
Answer:
Desertification, nutrients in the soil, access to water, tools made for agriculture, location, climate, water pollution, the production of the food product, etc.
Explanation:
There are many factors that contribute in the decision making of food choices and the growth and production of food. In able to have a productive farm, some farmers choose to use many workers, some choose to use large tools, like tractors and irrigation systems. If there is not enough water getting to the farm, in some places like California, they will make a system or transport the water to the farm. Climate and weather also play a big role. If the climate does not supply the right resources to the plants, they will not be able to grow properly. Some climates are able to grow certain plants better than in other regions. The process of the food production affects how some make their food choices. For example, some people dislike how animals are treated and cared for before they are used for meat. Then, these people make the decision to not eat meat at all or from some companies that mistreat their animals. When their is water pollution near-by farms, farmers will struggle to grow their crops. When chemicals, from these polluted water sources, travel through the soil to the farms, the crops die or are harmed. In places like Africa, with dry climates, they use one plot of land for growing crops, then move to another plot the next year, because the nutrients from that plot were used all up for growing those plants. Sometimes, they even burn the weeds and shrubs after the harvest because it provides the soil with nutrients. This method is called slash and burn.
Answer:
c. abiotic factors that are not involved in maintaining a population near its equilibrium.
Explanation:
They are both natural disaster and they are not dependent on the population.
