Tectonic hazards：練習題

Which of the following describes the correct tectonic process occurring at a constructive plate margin?

At which type of plate margin do tectonic plates slide past each other, resulting in earthquakes but typically no volcanic activity?

At a destructive plate margin involving an oceanic and a continental plate, why does an earthquake typically occur?

At which type of plate margin do two plates slide past each other, creating friction that leads to earthquakes without the formation of volcanoes?

Which of the following is a long-term response to a tectonic hazard, rather than an immediate response?

Identify one primary effect and one secondary effect that could occur following a major earthquake in a high-income country.

Describe the physical processes that occur at a constructive plate margin which lead to the formation of a mid-ocean ridge.

Explain the role of convection currents within the Earth’s mantle in driving the movement of tectonic plates according to plate tectonics theory.

Using named examples of tectonic events in areas of contrasting levels of wealth, compare the secondary effects and the long-term responses to these hazards.

In your answer, you should:
a) Define what is meant by a secondary effect of a tectonic hazard.
b) Explain how the wealth of a country influences the severity of secondary effects.
c) Evaluate why long-term responses are often more effective in Higher Income Countries (HICs) compared to Lower Income Countries (LICs).
