Answer:
Explanation:
The physical environment is the part of the environment made up of both man-made and natural features. They consist of some physical factors like water, soil, e.t.c. Mountains, rivers, valleys, hills, dams, lakes all makes up the physical aspect of our environment and much more.
The physical environment can limit human activities in the following ways:
- Barriers to communication and transportation: most times roads have to be cut through longer distances in order to bypass natural features like a huge mountains, a voluminous river e.t.c. This can severely impact the communication between places and people.
- Natural disasters: The physical environment can pose serious risk to humans through disasters such as earthquake, landslide, flooding, wildfires, e.t.c.
- Drought and famine: When several elements of the physical environment combines, they can lead to little to no rainfall for plant to thrive. This is very dangerous for life on earth. Human activities are connected a lot to how rich and useful a soil can be.
- Climate changes and global warming: Human activities are greatly impacted by changes in climate and weather. If too much rainfalls, it becomes a problem to farmers and human activities as a whole will suffer. If sunshine diminishes abnormally, the earth suffers as solar radiation is very key to life on earth.
Answer:
The intermediate magma has a heterogeneous structure, since it has a part of Silice, approximately 50-60% to be more exact.
When it turns into lava, it produces rocks like the Andesite and, in the opposite case of its crystallization, it forms rocks like the Diorite.
A comparison of felsic magma is much more viscous.
It is important to clarify that this magma is a type of primary magma, that is to say that they are magmas formed from the fusion of the rocks of the mantle or the crust.
Explanation:
The fusion of these rocks are what would give rise to the intermediate magma, this intermediate magma is a primary magma, like the mafic and felsic.
The primary magmas unlike the derived magmas is the origin or the reason for how they are formed, which is what we write above, derived magmas usually form differently since they are the product of the evolution or changes that magmas undergo primary
I believed the answer is b
Both Io nad Triton are moons that orbit around planets. Io<span> is the fifth moon out from </span>Jupiter, while Triton is the largest natural satellite of the planet Neptune.It <span>is similar in size to Earth’s moon and was discovered in 1846 .
</span><span>The similarities between Io and Triton</span> lays in the active volcanic like activities.
