① 向外星人介紹地球的英語作文
太陽系八大行星之一，地球自西向東自轉，同時又圍繞太陽公轉。地球自轉與公轉運動的結合使其產生了地球上的晝夜交替和四季變化(地球自轉和公轉的速度是不均勻的)。同時，由於受到太陽、月球、和附近行星的引力作用以及地球大氣、海洋和地球內部物質的等各種因素的影響，地球自轉軸在空間和地球本體內的方向都要產生變化。地球自轉產生的慣性離心力使得球形的地球由兩極向赤道逐漸膨脹，成為目前的略扁的旋轉橢球體，極半徑比赤道半徑短約21千米。
阿地球是由一系列的同心層組成。地球內部有核（地核）、幔（地幔）、殼（地殼）結構。地球外部有水圈和大氣圈，還有磁層，形成了圍繞固態地球的美麗外套。
地球作為一個行星，遠在56億年以前產生於原始太陽星雲。
One of the eight planets of the solar system, the earth rotation from the west to the east, and orbit the sun. The earth rotation and the combination of the revolution movement so as to proce a day and night on earth and seasons change (the earth rotation and the speed of the revolution is not uniform). At the same time, because of the sun, the moon, and by nearby planets gravity and the earth's atmosphere, ocean and earth's internal material factors, the earth spin axis in space and the direction of the earth in the body to proce change. The earth rotation inertia centrifugal force proced by the poles of the earth makes spherical graally expand to the equator, become the current slightly flat spin ellipsoid body, extremely radius than the equator short radius about 21 km.
O earth consists of a series of concentric layers. The interior of the earth have nuclear (core), curtain (mantle), shell (crust) structure. The earth's outer have hydrosphere and atmosphere, and magnetic layer, formed around of the solid earth beautiful coat.
The earth as a planet, far before 5.6 billion years proced in the primitive solar nebula.
② 地球的英文介紹（簡單一些）
earth id the third planet in distance outward from the Sun.
Believed to be about 4.6 billion years old, it is some 92,960,000 mi (149,600,000 km) from the Sun. It orbits the Sun at a speed of 18.5 mi (29.8 km) per second, making one complete revolution in 365.25 days. As it revolves, it spins on its axis, rotating once every 23 hours 56 minutes 4 seconds. The fifth largest planet of the solar system, it has an equatorial circumference of 24,902 mi (40,076 km). Its total surface area is roughly 197,000,000 sq mi (509,600,000 sq km), of which about 29% is land. Earth's atmosphere consists of a mixture of gases, chiefly nitrogen and oxygen. Its only natural satellite, the Moon, orbits the planet at a distance of about 238,860 mi (384,400 km). Earth's surface is traditionally subdivided into seven continental masses: Africa, Antarctica, Asia, Australia, Europe, North America, and South America. These continents are surrounded by the so-called World Ocean, which is broken down into three major bodies: the Atlantic, Pacific, and Indian oceans. Broadly speaking, Earth's interior consists of two regions: a core composed largely of molten, iron-rich metallic alloy; and a rocky shell of silicate minerals comprising both the mantle and crust (See also Moho; lithosphere). Fluid motions in the electrically conctive outer core generate a magnetic field around Earth that is responsible for the Van Allen radiation belts. According to the theory of plate tectonics, the crust and upper mantle are divided into a number of large and small plates that float on and travel independently of the lower mantle. Plate motions are responsible for continental drift and seafloor spreading and for most volcanic and seismic activity on Earth.
③ 用英語介紹我們的地球外貌，
Our Earth is a blue planet, with over 70% of the surface area under water. It looks like a ball with occasional landmass that can be seen from outer space, which we call continents. These continents are covered with green vegetation. But as our population grows, some of these forests are cut down and urbanized into small dots of cities. These cities light up ring night and are beautiful to watch from the sky, they look like miniatures of the universe.

⑤ 關於地球的資料用英語介紹六十詞左右
The area of desert in the world is growing every year. Many parts of the world which once had large populations and proced plenty of crops, have become deserts. Dunhuang in China, deep in the heart of the Gebi Desert, was once a great city.
Cattle are one cause of the problem. In good years, famers increase the numbers of their cattle. Then one year, the rains fail to come. The farmers do not want to kill any of their cattle, so the cattle eat ail the grass and anything that grows on poorer land. If this continues for several years, the grass never grows again and the land becomes a desert. One suggested answer is for farmers to limit the numbers of their cattle.
Another problem is that good soil is graally lost. When trees are cut down, there is nothing to hold the soil in place on the hillside. So when if rains, the soil is washed down the hills and into the rivers. Strong winds can also blow away the valuable soil that lies on the top of the fields.

⑦ 急求地球的介紹！得是英文！
The Earth's surface is very young. In the relatively short (by astronomical standards) period of 500,000,000 years or so erosion and tectonic processes destroy and recreate most of the Earth's surface and thereby eliminate almost all traces of earlier geologic surface history (such as impact craters). Thus the very early history of the Earth has mostly been erased. The Earth is 4.5 to 4.6 billion years old, but the oldest known rocks are about 4 billion years old and rocks older than 3 billion years are rare. The oldest fossils of living organisms are less than 3.9 billion years old. There is no record of the critical period when life was first getting started
71 Percent of the Earth's surface is covered with water. Earth is the only planet on which water can exist in liquid form on the surface (though there may be liquid ethane or methane on Titan's surface and liquid water beneath the surface of Europa). Liquid water is, of course, essential for life as we know it. The heat capacity of the oceans is also very important in keeping the Earth's temperature relatively stable. Liquid water is also responsible for most of the erosion and weathering of the Earth's continents, a process unique in the solar system today (though it may have occurred on Mars in the past).

About Earth
Planet Earth is something I hold dearly to my heart. It is not at the center of the Universe, but it is our home planet. Our mother that has allowed all existing life on Earth to be possible. It is at the right distance from the sun, so much so that any deviation could lead to the death of hundreds of species. The insane number of varieties of species on Earth is startling! However the Human's actions towards mother Earth is unnerving, seeing the many destroyed habitats across the planet, I beg to differ. It has been an honour to stand against human race to proudly support mother Earth. I love her, more than anything else, and I don't like the separation of countries, we all living on a single planet- Earth!
