Answer:
Option C, At a subduction zone, oceanic crust is forced deep into the Earth.
Explanation:
At sub-duction zone, the dense oceanic plates coincides with the less dense continental plates and thus sink below the continental plates. Sometimes these oceanic plates being dense, sink to greater depth with in the earth’s mantle. The sub-duction zone causes earth quakes of high intensity when oceanic crust penetrates to greater depths of earth crust as they tend to change the rheology of the earths’ mantle and also causes bending of plates
Hence, option C is correct
Answer:
All these are emerging infectious diseases.
Explanation:
The emerging infectious diseases refer to the infections, which have appeared freshly within a population or those whose occurrence or geographic range is enhancing briskly or is threatening to upsurge in the coming time. The emerging infections can be a result of:
1. Known agents, which have dispersed to novel geographic locations or new populations.
2. Previously unknown or undetermined infectious agents.
3. Previously known agents whose function in particular diseases was not determined previously.
According to WHO, infectious diseases are emerging at a rate, which has not been noticed before. Since the 1970s, many infectious diseases have been discovered like Ebola, SARS, avian influenza, mad cow disease, and West Nile encephalitis.
With the individuals traveling much more to far greater distances in comparison to the past, encountering with wild animals, and living in more densely populated regions has caused the emerging infectious diseases to spread briskly and is resulting in global epidemics, which is a major worry.
Hydrologists measure the properties of bodies of water. For example, volume and stream flow.
