How can the function of the turbine in a geothermal power plant be explained in terms of energy transformation? The turbine____________.

converts thermal energy to mechanical energy to electrical energy

converts the mechanical energy to chemical energy to thermal energy

cools the steam before it reaches the condensing tower

turns the hot water into steam for further use

Why is it important for the steam in a geothermal plant to be condensed before being reinjected into the ground? To_____________________.

recycle the water and ensure the continuous use of geothermal energy without depleting resources

maintain the pressure needed to drive the turbine and continue to function

cool down the hot rocks underground and prevent the magma to heat the rocks

prevent the steam from becoming too hot and causing environmental damage

How would a decrease in the temperature of the hot rock/soil below the geothermal plant affect the entire energy production process? It would _______________.

reduce the amount of steam generated

increase the amount of steam generated

make the steam too hot, causing damage to the turbine

have no effect on energy production

What will be the efficiency of a geothermal powerplant might change if the condensing tower were removed from the system.

The steam would not cool down, and the plant would be unable to reuse the water

The plant would generate more electricity because there would be no need to cool the steam

The plant’s efficiency would remain the same because cooling the steam is unnecessary for power generation

The steam would be cooler, increasing the amount of energy produced by the generator

Ideas for more sustainable cities In 2020. over 56% of the world s population lived in urbon arcos. Cities are becoming more and more popular. But why isn't rural life as attractive as city life? The main reasons include work. lifestyle education and Sea th in cities there ore more fun things to see and do, like art galleries, concert hails and sports stadiums, There are a so better hospitals, transport na anueners However, as cities become more overcrowded, they get more polluted. For this reason, urban residents want to make their cities more sustainable. But how? Here are five ways: 1 New York's Central Pork is an island of green in a forest of skyscrapers. City parks like these provide people with a peaceful ploce to connect with nature. and o quiet area for exercise. 2 The moming and evering tush hours lare the busest times in the city. When people commute* to and from work or school, they need frequent, fast public transport, like trams and underground troins. Transport should also be as cheap as possible - and accessible to those with less mobility, like older people or wheelchair users. 3 Cities need pleasant places for people to meet and so shopping. So they should have more pedestr on zones, like in Copenhagen, Denmark, Copenhagen has the world's longest pedestrion street. It's almost 3.2 km long! Pedeston aones encourage ' people to go shopping on foot, instead of driving to shopping malls. 4 1 kes are often the quickest and most susta nable. way to get around, but mony city streets are frenetic and dangerous. Sa susto nable cities have cycle paths, as well as public bikes ond e scooters. They alto have hybrid buses and lots of car charging points. 55 Cities need to encourage residents to care about the environment, with fun ecological exhibitions" and events. The Supertree Gardens in Singapore are amazing, ver fal botanic gardens. They are 50 metres high and the /se solor energy. Eco-festivols - lIke Terroformo in Milan, Italy, and the Secret Solstice in Reykjavik, Iceland - use solar and geothermol energy. They're some of the most sustoinable festiois in the wortd
