The continent with the largest population is africa
In this question, there are no options given. So we have to answer based on our knowledge. Aid agencies estimated that approximately four million residents of Ethiopia required food aid in 2009. Ethiopia is a country that has long suffered from drought and famine. The people of Ethiopia has long survived on the basis of the food aids they have received.
Answer:
Question 8 is true
.
Question 9, the correct answer is c, when basalt lava flows cover very large areas of continental crust.
QUESTION 10, the right option is d high viscosity, high gas content.
Explanation:
The viscosity of magma depends on its temperature, composition and gas content. Thus, magma with high levels of Sio2, silicon dioxide or silica increases the resistance flow as it increases lava viscosity, due to greater degrees of “internal friction”. Whereas basalt magma has a low-silica composition and flow fairly easily.
The Earth’s surface is transformed by high volume eruptions made of basaltic lava. Convection currents in the mantle find their way to the surface in randomly generated hot spots covering vast areas of lands. The geothermal conditions of these provinces affect their geography.
The volcanic explosiveness relies on the amount of gas and the degree of viscosity of magma. That is to say that high levels of gas mixed together with high viscosity rate result in highly explosive bursts. The eruptive force correlates to the internal pressure and the expansion of gas due to the friction caused by the resistance to flow.
Answer:
D
Explanation:
mountains often have rough, uneven terrain, making it hard to build structures or farm.
