Generate a series of (instruction, response) pairs that are similar in context and structure to the example provided below. Each pair should consist of a concise instruction followed by an appropriate, detailed response. The instruction should pose a clear task or question, while the response should provide a comprehensive answer or solution that could be understood by someone with a basic understanding of the subject.

Example pair: 
Instruction: Sum up what the following article says about why Americans are experiencing a “friendship recession.”

So it is alarming that Americans are experiencing a “friendship recession.”

The startling decline of friendship
Modern living is tough on friendship.Unlike our ancestors who knew everyone in their tribe, most people now live in cities where the default is anonymity. As children and young adults, school may provide a social community. Indeed, the number of friends people have peaks around age 25, but then substantially drops around age 30, when work and the nuclear family take over.

Americans, especially those who are highly educated and high-earning, work longer hours and are more likely to move for work than ever before. Parents also spend twice as much time with their children than previous generations. This saps the ability to maintain close friendships.

The last decade has seen a startling further fall in the number and quality of friendships.
Response: There are many reasons why Americans are seeing a decline in the number and quality of friendships over the last decade. A couple of these reasons may be attributed to many Americans working longer hours and parents spending more time with their children than in prior generations.

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.

Summarize the key concepts about the theory of plate tectonics and how it explains the movement of the Earth's continents and oceans from the following text:

The theory of plate tectonics is a unifying theory that explains the formation, movement, and interactions of the Earth's lithospheric plates. The Earth's outer shell, called the lithosphere, is divided into several rigid plates that move slowly across the underlying mantle. These plates are composed of both continental and oceanic crust. The movements of these plates are driven by convection currents in the Earth's mantle, which cause the plates to either converge, diverge, or slide past one another. At convergent boundaries, where plates collide, one plate may be forced beneath the other, forming a deep ocean trench and causing volcanic activity and mountain building. At divergent boundaries, such as mid-ocean ridges, plates move apart, allowing molten rock from the mantle to rise and create new oceanic crust. Transform boundaries involve plates sliding horizontally past each other, often resulting in earthquakes along fault lines. The theory of plate tectonics explains the distribution of earthquakes, volcanoes, mountain ranges, and the continents' positions and shapes over geological time. It also provides a framework for understanding the recycling of materials between the Earth's crust and mantle.

The key concepts about the theory of plate tectonics and the movement of continents and oceans are: 1) The Earth's outer shell (lithosphere) is divided into several rigid plates composed of continental and oceanic crust. 2) These plates move slowly across the underlying mantle, driven by convection currents. 3) At convergent boundaries, plates collide, causing one to be subducted, forming trenches, volcanic activity, and mountain building. 4) At divergent boundaries, like mid-ocean ridges, plates move apart, allowing new oceanic crust to form. 5) Transform boundaries involve plates sliding horizontally past each other, causing earthquakes along fault lines. 6) Plate tectonics explains the distribution of earthquakes, volcanoes, mountain ranges, and the positions and shapes of continents over time. 7) It also provides a framework for understanding the recycling of materials between the Earth's crust and mantle.
