Answer:
1. Weather is the day-to-day state of the atmosphere, and its short-term variation in minutes to weeks. People generally think of weather as the combination of temperature, humidity, precipitation, cloudiness, visibility, and wind.
2.The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. ... The absorbed energy warms the atmosphere and the surface of the Earth.
3.Hydrogen fuel cell vehicles
Hydrogen-fueled vehicles emit virtually no hydrocarbons, particulates, carbon dioxide, or carbon monoxide.
C.Global warming is that the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900) thanks to human activities, primarily fuel burning, which increases heat-trapping greenhouse emission levels in Earth's atmosphere.
