The moon origin mystery: for lunar origins, scientists put forward three kinds of theories: capture said, homology and earth divided them all defective, said, but the Apollo would help proof, which seem least likely theory is the best theory. Some scientists think, the moon is with earth in 46 billion years ago, from a group of cosmic st generator. Another theory is that the moon is the earth's "children", is perhaps the Pacific "dig" out. However Apollo moon exploration results show that the earth and the moon the composition of the difference is very big, some scientists have proposed another hypothesis, namely "captured". They think that the moon is accidentally broke into gravitational field, and be locked in the present orbit. However, it is theoretically explain the process mechanism, is extremely difficult. Therefore, the above three theory all difficult to hold water. As robin hallam especially by dr said: "to explain the moon does not exist, than to explain the moon exist easier."
The moon age riddle: what is amazing is that the rock samples from the moon back, via analysis found that about 99 percent age than earth 90% oldest rocks more older. Armstrong in "quiet sea" after landing picked up the first piece of rock's age is 36 billion years old. Some other rock age 4.3 billion years old, 4.6 billion years old and 45 billion years old — — it almost and earth and solar system itself, the earth is as old as the oldest rocks is 37 billion years old. In 1973, the world symposium on the moon was a age determination for 53 billion years old of moon rocks. Is more surprising is that these ancient rocks are collected from scientists believe to be the youngest area on the moon. In light of the evidence, some scientists propose that the moon on earth formed before long was established in interstellar space formed.
The lunar soil years older than rock greater mystery: the moon ancient rock has made scientists helpless, however, and these rocks, compared to the

The Sun and The Earth
The sun shines on us. It gives us light and heat. It makes everything grow. It gives the earth life.
The earth turns round itself. As it turns, we have day and night. It's bright by day and dark by night.

Ⅵ 關於太陽的英語短文
這個蠻短的:
The Sun is the most prominent feature in our solar system. It is the largest object and contains approximately 98% of the total solar system mass. One hundred and nine Earths would be required to fit across the Sun's disk, and its interior could hold over 1.3 million Earths. The Sun's outer visible layer is called the photosphere and has a temperature of 6,000° (11,000°F). This layer has a mottled appearance e to the turbulent eruptions of energy at the surface.
Solar energy is created deep within the core of the Sun. It is here that the temperature (15,000,000° C; 27,000,000° F) and pressure (340 billion times Earth's air pressure at sea level) is so intense that nuclear reactions take place. This reaction causes four protons or hydrogen nuclei to fuse together to form one alpha particle or helium nucleus. The alpha particle is about .7 percent less massive than the four protons. The difference in mass is expelled as energy and is carried to the surface of the Sun, through a process known as convection, where it is released as light and heat. Energy generated in the Sun's core takes a million years to reach its surface. Every second 700 million tons of hydrogen are converted into helium ashes. In the process 5 million tons of pure energy is released; therefore, as time goes on the Sun is becoming lighter.
The chromosphere is above the photosphere. Solar energy passes through this region on its way out from the center of the Sun. Faculae and flares arise in the chromosphere. Faculae are bright luminous hydrogen clouds which form above regions where sunspots are about to form. Flares are bright filaments of hot gas emerging from sunspot regions. Sunspots are dark depressions on the photosphere with a typical temperature of 4,000°C (7,000°F).
The corona is the outer part of the Sun's atmosphere. It is in this region that prominences appears. Prominences are immense clouds of glowing gas that erupt from the upper chromosphere. The outer region of the corona stretches far into space and consists of particles traveling slowly away from the Sun. The corona can only be seen ring total solar eclipses.
The Sun appears to have been active for 4.6 billion years and has enough fuel to go on for another five billion years or so. At the end of its life, the Sun will start to fuse helium into heavier elements and begin to swell up, ultimately growing so large that it will swallow the Earth. After a billion years as a red giant, it will suddenly collapse into a white dwarf -- the final end proct of a star like ours. It may take a trillion years to cool off completely.
Ⅶ 求一篇關於Solar Energy(太陽能)的英語作文,不少於100詞。
With the improvement of living standards, solar energy has become part of our lives. Solar power is the use of solar battery components will be directly converted into electrical energy device. Solar cell mole (Solar cells) is a solid device to realize P-V conversion using the electronic properties of the semiconctor material, in the absence of power network area is vast, the device can conveniently realize the lighting and power supply for users living, some developed countries can also achieve complementary and regional grid.
Ⅷ 關於介紹太陽系的英語作文就,100字以上
太陽系 (Solar System)就是我們現在所在的恆星系統。它是以太陽為中心,和所有受到太陽引力約束的天體的集合體:8顆行星[冥王星已被開除]、至少165顆已知的衛星,和數以億計的太陽系小天體。這些小天體包括小行星、柯伊伯帶的天體、彗星和星際塵埃。
廣義上,太陽系的領域包括太陽、4顆像地球的內行星、由許多小岩石組成的小行星帶、4顆充滿氣體的巨大外行星、充滿冰凍小岩石、被稱為柯伊伯帶的第二個小天體區。在柯伊伯帶之外還有黃道離散盤面、太陽圈和依然屬於假設的奧爾特雲。
依照至太陽的距離,行星序是水星、金星、地球、火星、木星、土星、天王星、海王星,(離太陽較近的水星、金星、地球及火星稱為類地行星,其餘均為行星)8 顆中的7顆有天然的衛星環繞著,這些星習慣上因為地球的衛星被稱為月球而都被視為月球。在外側的行星都有由塵埃和許多小顆粒構成的行星環環繞著,而除了地球之外,肉眼可見的行星以五行為名,在西方則全都以希臘和羅馬神話故事中的神仙為名。太陽系內天體的軌道
[編輯本段]1.概述和軌道
太陽系的主角是位居中心的太陽,它是一顆光譜分類為G2V的主序星,擁有太陽系內已知質量的99.86%,並以引力主宰著太陽系。木星和土星,是太陽系內最大的兩顆行星,又佔了剩餘質量的90%以上,目前仍屬於假說的奧爾特雲,還不知道會佔有多少百分比的質量。
太陽系內主要天體的軌道,都在地球繞太陽公轉的軌道平面(黃道[1])的附近。行星都非常靠近黃道,而彗星和柯伊伯帶天體,通常都有比較明顯的傾斜角度。
由北方向下鳥瞰太陽系,所有的行星和絕大部分的其他天體,都以逆時針(右旋)方向繞著太陽公轉。有些例外的,像是哈雷彗星。
環繞著太陽運動的天體都遵守開普勒行星運動定律,軌道都以太陽為橢圓的一個焦點,並且越靠近太陽時的速度越快。行星的軌道接近圓形,但許多彗星、小行星和柯伊伯帶天體的軌道則是高度橢圓的。
在這么遼闊的空間中,有許多方法可以表示出太陽系中每個軌道的距離。在實際上,距離太陽越遠的行星或環帶,與前一個的距離就會更遠,而只有少數的例外。例如,金星在水星之外約0.33天文單位的距離上,而土星與木星的距離是4.3天文單位,海王星又在天王星之外10.5天文單位。曾有些關系式企圖解釋這些軌道距離變化間的交互作用。
[編輯本段]2.形成和演化
藝術家筆下的原行星盤太陽系的形成據信應該是依據星雲假說,最早是在1755年由康德和1796年由拉普拉斯各自獨立提出的。這個理論認為太陽系是在46億年前在一個巨大的分子雲的塌縮中形成的。這個星雲原本有數光年的大小,並且同時誕生了數顆恆星。研究古老的隕石追溯到的元素顯示,只有超新星爆炸的心臟部分才能產生這些元素,所以包含太陽的星團必然在超新星殘骸的附近。可能是來自超新星爆炸的震波使鄰近太陽附近的星雲密度增高,使得重力得以克服內部氣體的膨脹壓力造成塌縮,因而觸發了太陽的誕生。
被認定為原太陽星雲的地區就是日後將形成太陽系的地區,直徑估計在7,000至20,000天文單位,而質量僅比太陽多一點(多0.1至0.001太陽質量)。當星雲開始塌縮時,角動量守恆定律使它的轉速加快,內部原子相互碰撞的頻率增加。其中心區域集中了大部分的質量,溫度也比周圍的圓盤更熱。當重力、氣體壓力、磁場和自轉作用在收縮的星雲上時,它開始變得扁平成為旋轉的原行星盤,而直徑大約200天文單位,並且在中心有一個熱且稠密的原恆星。
對年輕的金牛T星的研究,相信質量與預熔合階段發展的太陽非常相似,顯示在形成階段經常都會有原行星物質的圓盤伴隨著。這些圓盤可以延伸至 ... 展開全部>

Ⅸ 英語寫作日出
During the May Day holiday, my parents and I climbed Mount Tai. We were lucky that it was fine that day and we were able to see the sunrise.
At 4:30 in the morning we were already,on the top, waiting for the sun to rise.First a bit of pale ray appeared in the east, then it became brighter and brighter. An orange top of a cap rose little by little from the sea. Suddenly, the sun sprang out of the seawater, looking like a large elliptic ball, and the sky in the east became red. Later, the sun was hidden behind a piece of cloud. When it appeared again, the sun changed from red to bright red, then to golden. AS it rose it became silvery white and shone out. The light was so strong that we could't look at it directly.At that time,the whole mountain was in the golden sunlight.
日出
五一長假期間,我和父母登上了泰山。彳艮幸運,那天天氣晴朗,我們看到了日出。
早晨四點半,我們已經爬上了山頂,等待太陽的升起。首先,一抹淡白出現在東方,然後漸漸變得明亮。一輪橘黃色的帽頂慢慢從海上升起,突然太陽噴薄而出,看上去像一個橢圓形大球;東方的天空布滿朝霞。後』采,太陽躲在了一片雲後,當它再次露出臉龐,由鮮紅變為金黃。隨著太陽升起,它變成銀白色,放出耀眼的光芒,我們不敢直視。這時,整座山沐浴在金色的陽光之中。
