Which statement explains why earthquakes tend to be deeper near subduction zones?
ICE Princess25 [194]

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

As far as human surveillance goes, people can track other people by tailing them or by using a stationary means such as a stake out. As far as technology goes, there are plenty of mobile devices that can be used for surveillance such as tracking devices. Security cameras can be used for stationary purposes.</span>

Andrei [34K]

Answer:

<em>The correct option is D) immigration</em>

Explanation:

Immigration can be described as the movement of an organism to another place for living. As the scenario in the question tells, the population of the endangered Philippine eagle could be seen only in one place hence we can say that the immigration rate of these organisms was zero because they could not be seen in any other place.

Other option, like option B, cannot be correct because mortality refers to the death rate and obviously many organisms of the species died due to which it became endangered.
