Hello. You did not present the answer options, which makes it impossible for this question to be answered accurately. However, I will try to help you in the best possible way.
To produce electricity for a city in a developed country, photovoltaic solar farms would need to occupy a large amount of land, as the demand for electricity in developed cities is very high and this would require a high production of solar energy. The occupation of such a large piece of land could hinder the sustainability of the region and of this energy production system. This is because the occupation of large areas of land could promote the destruction of habitats, deforestation and water and soil pollution due to the hazardous materials that are used to build solar panels, such as lead, gallium arsenide, diselenide from copper-indium-gallium, among others. This would cause the production of a non-polluting type of energy, causing pollution due to its installation.
There are three major compositional groups of igneous rocks, mafic, felsic, and intermediate.
Mafic
The mafic igneous rocks are rich in magnesium and iron, making them a portmaneau of magnesium and ferric. They tend to be with dark coloration, with biotite and olivine being one of those rocks.
Felsic
The feslic igneous rocks are rich in elements that are forming the feldspar and quartz. Their coloration is lighter, and they come in numerous colors, with the granite and quartz being one of them.
Intermediate
The intermediate igneous rocks are in a way transitional rocks between the mafic and the felsic ones. They have a mixture of both mafic and felsic minerlas. Their coloration varies, and the andesite and dacite are some of them.
Hurricane, volcano and earthquake are the natural disasters that all have the potential to wreck havoc and impact the human populations. So the correct option among all the options given in the question is option "d".
Widening rivers can be a very important cause that can increase the risk of flooding. The correct option among all the options given in the question is option "d". If the humans deliberately cut the banks and widens the river, then it can cause floods during the rainy season as the banks become weak to hold the force of water that comes in.
After earthquakes happen, there will be smaller events which are known as <u>aftershocks</u>.
<h3>What are aftershocks?</h3>
These are smaller scale tremors that are felt after an earthquake has occured in a region.
They are usually more serious the close one is to the epicenter, and for really strong earthquakes, aftershocks can be quite dangerous.
In conclusion, option B is correct.
