Suppose a comet collided with the earth. Write a composition predicting the consequences of such a collision.
For the most part, a comet is an object in the solar system that orbits the sun sometimes has a coma (or atmosphere) and a tail. These characteristics are added mostly because of the effects of solar radiation upon the comet's nucleus (the nucleus is made of rock, dust, ice, etc.).
The interesting thing is that comets' orbits are highly variable. First, they are almost always highly affected by close calls with major planets, sometimes even being moved into orbits that destroy them due to their nearness to the Sun. One of the reasons why comets are so easily moved is because the outgassing that creates their comas and tails propels them in mysterious and unpredictable ways. But if a comet collided with the earth, what would happen then?
If the comet were small enough (and we survived), probably something similar to the situation on the 15th of April 1815, when volcanic eruptions of Mount Tambora ejected immense amounts of volcanic dust into the upper atmosphere, would happen." The year of 1816 (the year after) was often referred to as the Year Without a Summer.
This is because so much dust, from only one volcano, blocked out so much sunlight that several people froze to death and crops around the world died. Prices for food skyrocketed and it caused a major problem in economy.
The meteor that hit the Earth and resulted in the extinction of the dinosaurs probably kicked up 100 times to 1000 times as much dust as this volcano explosion.
So the consequences of such a supposed collision really depend on the size of the comet. The bigger it is, the more devastating its outcomes are.

Write a composition on the solar system.
The Solar System is made up of all the planets that orbit our Sun. In addition to planets, the Solar System also consists of moons, comets, asteroids, minor planets, and dust and gas.
Everything in the Solar System orbits or revolves around the Sun. The Sun contains around 98% of all the material in the Solar System. The larger an object is, the more gravity it has. Because the Sun is so large, its powerful gravity attracts all the other objects in the Solar System towards it. At the same time, these objects, which are moving very rapidly, try to fly away from the Sun, outward into the emptiness of outer space. The result of the planets trying to fly away, at the same time that the Sun is trying to pull them inward is that they become trapped half-way in between. Balanced between flying towards the Sun, and escaping into space, they spend eternity orbiting around their parent star.
How Did The Solar System form?
This is an important question, and one that is difficult for scientists to understand. After all, the creation of our Solar System took place billions of years before there were any people around to witness it. Our own evolution is tied closely to the evolution of the Solar System. Thus, without understanding from where the Solar System came from, it is difficult to comprehend how mankind came to be.
Scientists believe that the Solar System evolved from a giant cloud of dust and gas. They believe that this dust and gas began to collapse under the weight of its own gravity. As it did so, the matter in this could begin moving in a giant circle, much like the water in a drain moves around the center of the drain in a circle.
At the center of this spinning cloud, a small star began to form. This star grew larger and larger, as it collected more of the dust and gas that were collapsing into it.
Further away from the star that was forming in the center were smaller clumps of dust and gas that were also collapsing. The star in the center eventually ignited forming our Sun, while the smaller clumps became the planets, minor planets, moons, comets, and asteroids.

a presentation of the moon
The Moon is an earth satellite orbiting our planet from a distance of 384,000kms on average, and its orbit is in a west-to-east direction. Its surface gravity is only 0.16 that of the Earth (one sixth), and it does not seem to have life on it, since it has neither atmosphere nor water. Minimum and maximum temperatures on it are wide apart, with +110˚C on the sunlit side and –170˚C in lunar nights. The geology of this satellite is rock only, and its age is about 4,6 billion years.
Plans to reach the Moon on space crafts have been on scientists’ minds since early 20th century. But they became more concrete when the Russians launched space crafts Sputnik 1 and Sputnik 2 in 1957, the second one carrying dog Laika. In 1961, Yuri Gagarin orbited the Earth, followed by the American astronaut John Glenn in 1962. Finally, America won the honour of reaching the Moon before Russia, when Neil Armstrong set foot on it on July 21st 1969.
There are at present plans to build a space base on the Moon, to set a giant telescope and launch space ships from there to distant planets, and perhaps to other solar systems.
