Out of the choices given here, the one that would best categorize Canada's population is they are concentrated in the south. The correct answer is D.
Scientists make their opinion about the organisms that lived in an ancient environment based on multiple things. Fossils are very important because they show the organisms anatomy. The layers of the ground show the age and the basic climate information, as well as dramatic events in the Earth's history, like super volcano eruptions, meteor collisions, flooding's. Also the pollen is very important for knowing the environment, because it is everywhere and is preserved well, it gives clues about the climate, types of plants, the landscape, thus making opinion about the way of life of the organisms.
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.
