Leeds vs Earth

Informations

Leeds is the largest city in the county of West Yorkshire in Northern England, approximately 170 miles (270 km) north of central London. Leeds is the cultural, financial and commercial heart of the West Yorkshire Built-up Area (2011 census classification), the UK's fourth-most populous urban area with a reported population of 1.8 million in 2013.The city is served by five universities, has the UK's fourth-largest student population and the country's fourth-largest urban economy.It has one of the most diverse economies of all the UK's main employment centres and has seen the fastest rate of private-sector jobs growth of any UK city. It also has the highest ratio of private to public sector jobs of all the UK's Core Cities, with 77% of its workforce working in the private sector. Leeds has the third-largest jobs total by local authority area, with 480,000 in employment and self-employment at the beginning of 2015. Leeds is ranked as a "High Sufficiency" level city by the Globalization and World Cities Research Network.Leeds was a small manorial borough in the 13th century, becoming a major centre for the production and trading of wool in the 17th and 18th centuries, then a major mill town during the Industrial Revolution; wool was still the dominant industry, but flax, engineering, iron foundries, printing, and other industries were also important. From being a market town in the valley of the River Aire in the 16th century, Leeds expanded and absorbed the surrounding villages to become a populous urban centre by the mid-20th century.

Today, Leeds has become the largest legal and financial centre outside London with the financial and insurance services industry worth £13 billion to the city's economy. The finance and business service sector account for 38% of total output with more than 30 national and international banks located in the city, including an office of the Bank of England. Leeds is also the UK's third-largest manufacturing centre with around 1,800 firms and 39,000 employees; Leeds manufacturing firms account for 8.8% of total employment in the city and is worth over £7 billion to the local economy. The largest sub-sectors are engineering, printing and publishing, food and drink, chemicals and medical technology. Other key sectors include retail, leisure and the visitor economy, construction, and the creative and digital industries. The city saw several firsts, including the oldest-surviving film in existence, Roundhay Garden Scene (1888), and the 1767 invention of soda water.Public transport, rail and road communications networks in the region are focused on Leeds; the second phase of High Speed 2 will connect it to London via East Midlands Hub and Sheffield. Leeds currently has the third busiest railway station and the tenth busiest airport outside London. Leeds has a less extensive public transport coverage than other UK cities of comparable size, and is the largest city in Europe without any form of light rail or underground system.

Earth is the third planet from the Sun and the only astronomical object known to harbor life. About 29% of Earth's surface is land consisting of continents and islands. The remaining 71% is covered with water, mostly by oceans but also lakes, rivers and other fresh water, which together constitute the hydrosphere. Much of Earth's polar regions are covered in ice. Earth's outer layer is divided into several rigid tectonic plates that migrate across the surface over many millions of years. Earth's interior remains active with a solid iron inner core, a liquid outer core that generates Earth's magnetic field, and a convecting mantle that drives plate tectonics. According to radiometric dating estimation and other evidence, Earth formed over 4.5 billion years ago. Within the first billion years of Earth's history, life appeared in the oceans and began to affect Earth's atmosphere and surface, leading to the proliferation of anaerobic and, later, aerobic organisms. Some geological evidence indicates that life may have arisen as early as 4.1 billion years ago. Since then, the combination of Earth's distance from the Sun, physical properties and geological history have allowed life to evolve and thrive. In the history of life on Earth, biodiversity has gone through long periods of expansion, occasionally punctuated by mass extinctions.

Over 99% of all species that ever lived on Earth are extinct. Almost 8 billion humans live on Earth and depend on its biosphere and natural resources for their survival. Humans increasingly impact Earth's hydrology, atmospheric processes and other life. Earth's atmosphere consists mostly of nitrogen and oxygen. Tropical regions receive more energy from the Sun than polar regions, which is redistributed by atmospheric and ocean circulation. Greenhouse gases also play an important role in regulating the surface temperature. A region's climate is not only determined by latitude, but also by its proximity to moderating oceans and height among other factors. Extreme weather, such as tropical cyclones and heat waves, occurs in most areas and has a large impact on life. Earth's gravity interacts with other objects in space, especially the Sun and the Moon, which is Earth's only natural satellite. Earth orbits around the Sun in about 365.25 days. Earth's axis of rotation is tilted with respect to its orbital plane, producing seasons on Earth. The gravitational interaction between Earth and the Moon causes tides, stabilizes Earth's orientation on its axis, and gradually slows its rotation. Earth is the densest planet in the Solar System and the largest and most massive of the four rocky planets.
