Earth Hour Problem!!!!!

Don't be so extreme, this is formalism (I'm also annoyed by this).

Originally, this is an activity where form is greater than meaning.

But without such activities, most people would not have noticed the problem of global warming in their daily lives, and few would have taken action to protect the environment.

Turning off the lights for an hour won't help tackle global warming, but it's a reminder that environmental problems are real, so it's not useless.

The time in Australia is earlier than in China, and no one sleeps at six or seven o'clock in the afternoon.

Power generation in a power plant depends on the power and has nothing to do with the voltage. If there is less electricity, there will be no waste, and there will be other factories for production.

If there is no such "form over meaning" activity, is there a better way for landlords to remind people to pay attention to the environment? I don't think meaningless preaching is more motivating than an event like Earth Hour.

There's no way, ** has already put the words out, and you have to go formalism.

And ask the landlord, is there a way to call thermal power generation when you use electricity, and will thermal power generation cause damage to the environment?

Do you use electricity in a way called thermal power generation, and will thermal power generation cause damage to the environment?

Big brother's electrical appliances will heat up.

Earth Hour is a global energy-saving and environmental protection activity.

Write it yourself, don't rely on others, just write the truth.

Earth is one of the nine planets in the solar system, and is the third planet in descending order from closest to farthest from the sun. It has a natural satellite --- the Moon, which form a celestial system --- the Earth-Moon system.

The Earth rotates from west to east while revolving around the Sun. The combination of the Earth's rotation and its orbital motion produces the alternation of day and night and the changing seasons on Earth. The speed at which the Earth rotates is uneven.

At the same time, due to the gravitational effects of the sun, moon and planets, as well as the various effects of the atmosphere, oceans and internal materials of the earth, the direction of the earth's axis of rotation in space and the earth itself must change. The inertial centrifugal force generated by the rotation of the earth causes the spherical earth to gradually expand from the poles to the equator, becoming the current slightly flattened spheroid, with a polar radius about 21 kilometers shorter than the equatorial radius.

The Earth as seen by the Apollo spacecraft The Earth as seen by the Apollo spacecraft The Earth rises above the horizon of the Moon, and the Earth can be seen as consisting of a series of concentric layers. The Earth's interior has a core, mantle, and crust structure. The Earth's exterior has a hydrosphere and atmosphere, as well as a magnetosphere, forming a coat that surrounds the solid Earth.

Earth, as a planet, originated from the primordial solar nebula 4.6 billion years ago.

Earth Hour is an initiative of the World Wide Society for Nature (WWF) to address global climate change, hoping that individuals, communities, businesses and individuals will turn off their lights for an hour on the last Saturday of March from 20:30 to 21:30 to show their support for climate change action.

Earth Hour was first held on March 31, 2007 at 8:30 p.m. in Sydney, Australia, when more than 2.2 million homes and businesses in Sydney turned off their lights and appliances for one hour. According to later statistics, the electricity saved by turning off the lights for one hour is enough for 200,000 TVs to use for one hour, and 50,000 cars to run for one hour.

More citizens who participated reported that they could see several times more stars that night than usual. Subsequently, Earth Hour took the world by storm at a surprising speed from its humble beginnings. Just one year later, Earth Hour has been recognized as one of the world's biggest actions on climate change, becoming a global and growing event.

"Earth 1 Hour" is an initiative issued by the World Nature** to the world, calling on individuals, communities, enterprises and ** to turn off the lights for 1 hour on the last Saturday of March every year, in order to inspire people's sense of responsibility to protect the earth, as well as to think about environmental issues such as climate change, and show support for global action to fight climate warming.

Hello, in the first question: on the morning line, b on the dusk line, d on the date line, a (natural date line,), c (international date line).

The second question I didn't come out. I feel like there's something wrong with the question, and it seems like something went wrong.

Question 3: The northern hemisphere has equal days and nights, and you take a closer look at the original question to see if the question is wrong.

I hope mine is helpful to you.,Welcome to continue to ask.,,Hehe.。。

Of the four places, C is on the morning line, A is on the dusk line, and the one is on the date line.

2.At this point, A is 18 o'clock, B is 12 o'clock, and C is 6 o'clock.

I'm pretty sure mine is the correct answer:

Of the four places, B is on the morning line, D is on the dusk line, and A and C are on the heliological line

2.At this point, A is 0 o'clock, B is 6 o'clock, and C is 12 o'clock.
