Answer:
its the crust and a little bit of the upper mantle
Explanation:
I'm pretty sure that it is oil because that is what most of the countries over there use it, making it a trend.
Answer:
Geologist can use the following pieces of evidence in predicting future eruption;
1)Frequency of localize Earthquakes.
2)Gas Emissions.
3)Remote monitoring.
4)History of Volcanic Activity
Explanation:
<u>Frequency of Localize Earthquakes</u><u>:Geologists</u> use seismographs that record the length and strength of each earthquake to try to determine if an eruption is imminent.
<u>Gas emissions</u>:Gases may be able to escape a volcano before magma reaches the surface. Geologists measure gas emissions in vents on or around the volcano.The amounts of gases and their ratios are calculated to help predict eruptions.
<u>Remote Monitoring</u>:Some gases can be monitored using satellite technology. Satellites also monitor temperature readings and deformation. As technology improves, Geologist are better able to detect changes in a volcano accurately and safely.
<u>History of Volcanic Activity</u>:A volcano’s history, how long since its last eruption and the time span between its previous eruptions, is a good first step to predicting eruptions.
Answer:
to represents population distribution or to represent no of population
Answer:
Africa is the area which has the lowest amount of naturally available freshwater per capita.
Explanation:
Some parts of Africa have about 3879 m^3 of naturally available freshwater per capita. That is 12% of what is naturally available in South America, for instance.
