撞击地球的流星,小行星和其他空间碎片实际上很常见。然而,由于我们良好的思考氛围,这些外星大块岩石的极大部分通常不会使它到地球表面造成损害。然而,地球并没有总是有一个大气层让岩石在进入陆地之前燃烧起来。就像火山一样,陨石撞击会严重改变气候并导致地球物种发生重大变化 – 包括大规模物种灭绝。事实上,墨西哥尤卡坦半岛附近的巨大流星撞击被认为是中生代末期消灭恐龙的大规模灭绝的原因。这些撞击还可以将灰尘和灰尘释放到大气中,并导致到达地球的太阳光量发生很大变化。这不仅影响全球温度,而且长时间没有阳光会影响能够进行光合作用的植物的能量。如果没有植物产生能量,动物就会耗尽能量进食并保持活力。地球是我们太阳系中唯一具有已知生命的行星。造成这种情况的原因有很多,例如我们是唯一拥有液态水的行星,也是唯一一个在大气中含有大量氧气的行星。自地球形成以来,我们的气氛经历了许多变化。最重要的变化发生在所谓的氧气革命中。随着生命开始在地球上形成,大气中几乎没有氧气。随着光合生物成为常态,它们的废氧在大气中徘徊。最终,使用氧气的生物进化并繁衍生息。现在大气层的变化,由于燃烧化石燃料而增加了许多温室气体,也开始对地球上物种的进化产生一些影响。全球温度每年增加的速度似乎并不令人担忧,但它正在导致冰盖融化,海平面上升,就像它们在过去大规模灭绝期间所做的那样。

英国基尔大学天文学论文代写:小行星

Meteors, asteroids and other space debris that hit the Earth are actually very common. However, due to our good atmosphere of thinking, the vast majority of these extravagant large rocks usually do not cause damage to the Earth’s surface. However, the Earth does not always have an atmosphere that allows the rock to burn before it enters the land. Like a volcano, a meteorite impact can severely alter the climate and cause major changes in the Earth’s species – including mass extinction. In fact, the huge meteor impact near the Yucatan Peninsula in Mexico is believed to be the cause of the mass extermination of the dinosaurs in the late Mesozoic era. These impacts also release dust and dust into the atmosphere and cause a large change in the amount of sunlight that reaches the Earth. This not only affects global temperatures, but also the absence of sunlight for a long time affects the energy of plants capable of photosynthesis. If no plants produce energy, the animals will run out of energy and stay alive. The Earth is the only planet in our solar system with known life. There are many reasons for this. For example, we are the only planet with liquid water and the only planet that contains a lot of oxygen in the atmosphere. Since the Earth’s formation, our atmosphere has undergone many changes. The most important change occurred in the so-called oxygen revolution. As life begins to form on Earth, there is almost no oxygen in the atmosphere. As photosynthetic organisms become the norm, their spent oxygen smashes in the atmosphere. Eventually, organisms that use oxygen evolve and thrive. Changes in the atmosphere now, due to the burning of fossil fuels, have increased many greenhouse gases and have begun to have some impact on the evolution of species on Earth. The rate of global temperature increase every year does not seem to be worrying, but it is causing the ice sheets to melt and the sea level to rise, as they did during the mass extinction in the past.
