True, viral STIs are not curable and can only be controlled with medications
Geosphere...often known as lithosphere...is affected as atmosphere (air) is polluted and other factors
The main zone for these phenomena in at least the western world is the Circum-Pacific Ring of Fire Belt. This is exemplified by the Western Cordillera in BC (Rockies and Coast Mts) in BC with a few inactive volcanoes, the volcanoes on the western margin of the US such as in Northern Californa and the Sierra Nevada, and the volcanoes in western and central Mexico and then the Andes with its' frequent western volcanoes and then in Japan and Indonesia with their volcanoes as well. Earthquakes are common in this Belt and occur due to plate movements including subduction below the BC coast and under the Andes.
Answer: Option (C)
Explanation: Wegener's theory of Continental drift was replaced by a modern theory called the 'plate tectonic theory'. This theory was able to prove what wegener could not and so was universally accepted.
The new evidences supporting this theory were-
- The coastlines of east America and west Africa are similar in shape suggesting that they might have existed together once upon a time
- Similar fossils were found at different continents such as the glossopteris fauna
- Similar rock sequences found at different places determined by the correlation method
Hence the correct option that satisfies the above question is option (C)
