Summarize the main points of this excerpt from a science textbook: "The Earth's atmosphere is a layer of gases that surrounds the planet. It is essential for life, as it provides oxygen for breathing, protects us from harmful radiation, and helps to regulate the Earth's temperature. The atmosphere is composed of 78% nitrogen, 21% oxygen, and 1% other gases, including carbon dioxide, argon, and neon. The atmosphere is divided into several layers, each with its own characteristics. The troposphere is the lowest layer and contains most of the Earth's weather. The stratosphere contains the ozone layer, which absorbs harmful ultraviolet radiation from the sun. The mesosphere, thermosphere, and exosphere are the other layers, with each playing a crucial role in the Earth's climate system."

The Earth's atmosphere, composed primarily of nitrogen and oxygen, is essential for life. It provides breathable oxygen, protects us from harmful radiation, and regulates temperature. The atmosphere is divided into several layers, each with unique characteristics, including the troposphere, stratosphere, mesosphere, thermosphere, and exosphere, each contributing to the Earth's climate system.

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: Quickly summarize this paragraph below. 

A very familiar bird over most of North America, running and hopping on lawns with upright stance, often nesting on porches and windowsills. The Robin's rich caroling is among the earliest bird songs heard at dawn in spring and summer, often beginning just before first light. In fall and winter, robins may gather by the hundreds in roaming flocks, concentrating at sources of food.
Response: Robins nest in windowsills and porches in North America, sing from spring to summer, and flock in groups for food in fall and winter.

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.
