Summarize the key information about the formation and structure of the Earth, based on the following details:  

The Earth formed approximately 4.6 billion years ago from a massive, rotating cloud of gas and dust known as the solar nebula. Over hundreds of millions of years, gravity caused these materials to clump together, forming the Sun at the center and the planets orbiting around it.

As the Earth took shape, heavier molten materials like iron and nickel sank toward the center, forming the core. Lighter rocky materials formed the mantle around the core, and the lightest materials solidified as the crust on the surface.

The Earth is composed of three main layers: the crust, mantle, and core. The crust is a thin, solid outermost layer made of lightweight rocks like granite and basalt. The mantle is a dense, semi-molten layer of hot rock that extends about 1,800 miles (2,900 km) below the crust. At the center is the core, which consists of an extremely hot liquid outer core and a solid inner core composed mainly of iron and nickel.

The core generates the Earth's magnetic field, which protects the planet from harmful solar radiation. Heat from the core also drives the movement of tectonic plates in the crust and mantle, causing volcanic activity, earthquakes, and the formation of mountains and ocean basins over geological timescales.

The Earth formed around 4.6 billion years ago from the gravitational collapse of a rotating cloud of gas and dust. Over time, denser materials sank inward, forming a layered structure with a solid iron-nickel inner core surrounded by a liquid outer core, a thick, semi-molten mantle, and a thin, solid crust of lightweight rocks on the surface. This layered composition, with the core generating a protective magnetic field and heat driving tectonic plate motion in the mantle and crust, has shaped the Earth's geology over billions of years through processes like volcanic eruptions, earthquakes, and mountain building. The formation and internal structure of the Earth set the stage for the dynamic processes that continue to shape our planet's surface environments.

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: Please write a summary, in simple language, of who Daisy Eagan is using the following:

Throughout her multi-decade career, Tony award-winner Daisy Eagan has dazzled audiences from the stage to television and film, and with her writing. Next stop – time to take over the podcast world.
 
At age eleven, Eagan became the youngest actress to win a Tony Award for Best Performance by A Featured Actress for playing Mary Lennox in “The Secret Garden.” In 2016, Eagan returned to “The Secret Garden” to play Martha for the 25th anniversary concert production at Lincoln Center and at the Shakespeare Theatre in Washington, DC. Eagan also appeared on Broadway in “Les Miserables” and “James Joyce's The Dead,” and most recently on stage she starred in the First National Tour of Stephen Karam’s Tony-winning play, “The Humans.”
 
On television, Eagan can be seen on Freeform’s critically-acclaimed series “Good Trouble.” Additional television credits include HULU’s “The Path,” HBO’s “Girls,” CBS’ “The Mentalist,” “Without a Trace,” “Ghost Whisperer,” “The Unit” and “Numb3rs.”
 
A published award-winning writer with a loyal and growing audience, Eagan is a fierce fighter and activist for women's and LGBTQ rights. She is a rousing voice in political arenas and continues to fight for change throughout her literary career. She has written op-eds for publications including HuffPost and Playbill.com and had a column for USA Today Network’s The Journal News.
Response: Daisy Eagan is an award-winning stage and television actress, writer, and activist, and now can add podcaster to her list of roles. At only 11 years old, she won a Tony Award, she was the youngest actress to win such a prestigious award. She has appeared in several TV series, including The Path, Girls, and The Mentalist. Eagan is also an award-winning writer, activist, and a rousing voice in politics. 

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.
