由第三段中的 Pressure (压力) from the sunlight would keep the little spaceships in position around the earth… 可知,来自太阳光的压力可使这个小空间站定位在地球的一定距离内,故排除A项;由第三段中的 …mini-umbrellas together could reflect 1.8 percent of sunlight back. 可知,这种微型伞总共只能反射...
根据第二段最后一行句子that means light can pass it directly to reach the earth,with lands and oceans clearly in view.这意味着光可以直接通过它到达地球,陆地和海洋清晰可见.和第三段第二行句子this allows sunlight to be reflected(反射) back to space easily,causing the temperature of the earth's ...
Earth: Mars: Jupiter: Saturn: Uranus: Neptune:
Earth, third planet from the Sun and the fifth largest planet in the solar system in terms of size and mass. Its single most outstanding feature is that its near-surface environments are the only places in the universe known to harbor life. Learn more ab
NASA graphic showing the average temperatures of planets in the solar system.(Image credit: NASA/Lunar and Planetary Institute) Mars's atmosphereis about 100 times thinner than Earth's. Without a "thermal blanket," Mars can't retain any heat energy. On average, the temperature on Mars is ab...
In the past 200 years, the earth's temperature has increased greatly. It's reported that an increase in the temperature of about 0.7 ℃ appeared at the end of last century. 5. A Some scientists think mini-umbrellas(微型伞) might reduce the earth's temperature.6. G Roger Angel, a scien...

Finally, if bias in the temperature sensitivity of ecosystem respiration represented by standalone TBM simulations is indicative of that in coupled Earth system model simulations, we may expect the response of ecosystem respiration to warming to be stronger in those models than what current atmospheric...
The glass boards(玻璃板) of the greenhouse let in light but keep heat from escaping. This causes the greenhouse to heat up, much like the inside of a car parked in sunlight, and keeps the plants warm enough to live in the winter. The Earth's atmosphere is all around us. It is the...
