What doesn39。t really affect the water draining from the sink like some people suppose.)The Sun gets much of the credit for creating both wind and rain. When the Sun warms air in a specific location, that air rises, creating an area of low pressure. More air rushes in from surrounding areas to fill the void, creating wind. Without the Sun, there wouldn39。s summer there, and in the other hemisphere it39。s temperature by standing outside on a partly cloudy day. When the Sun is behind a cloud, you fuel noticeably cooler than when it isn39。s, and about a million Earths could fit inside the Sun. The Sun is inconceivably, mindbogglingly bigger. But without the Sun, the Earth could not exist, in a sense, the Earth is a giant machine, full of moving parts and plex systems. All those systems need power, and that power es from the Sun. The Sun is an enormous nuclear power sourcethrough plex reactions, it transforms hydrogen into helium, releasing light and heat. Because of these reactions, every square meter of our planet39。 to a lot of people, the Earth is inconceivably, mindbogglingly big. And it39。大學(xué)英語四級考試Model Test ThreePart Ⅰ WritingDirections: For this part, you are allowed 30 minutes to write a letter.

From our perspective on Earth, the Sun looks very small. This is because it39。s surface gets about 342 Watts of energy from the Sun every year. This is about 1017 Watts total, or as much as billion large power plants could generate. You can learn about how the Sun creates energy in How the Sun Works. When this energy reaches the Earth, it provides power for a variety of reactions, cycles and systems. It drives the circulation of the atmosphere and the oceans. It makes food for plants, which many people and animals eat. Life on Earth could not exist without the Sun, and the planet itself would not have developed without it. To a casual observer, the Sun39。t. The surface of our planet absorbs this heat from the Sun and emits it the same way that pavement continues to give off heat in the summer after the Sun goes down. Our atmosphere does the same thingsit absorbs the heat that the ground emits and sends some of it back to the Earth. The Earth39。s winter. This effect is less dramatic near the equator than at the poles, since the equator receives about the same amount of sunlight all year. The poles, on the other hand, receive no sunlight at all during their winter months, which is part of the reason why they39。t be wind. There also might not be breathable air at all.Water and Fire The Sun has a huge effect on our water. It warms the oceans around the tropics, and its absence cools the water around the poles. Because of this, ocean currents move large amounts of warm and cold water, drastically affecting the weather and climate around the world. The Sun also drives the water cycle, which moves about 18,757 cubic miles (495,000 cubic kilometers) of water vapor through the atmosphere every year. If you39。t the Coriolis Effect cause?
