Section 1: Plate tectonics is the the theory that the outer crust of the earth is cut up into a lot of pieces called plate tectonics. The plate tectonics move around in the mantle. The mantle is the rocky middle layer of our earth it lies right above the core. The plates are very much like a shel going around the earth. The evidence of plate tectonics began as simply circumstantial evidence one example is continental drift which is the theory that all the continents used to be one giant…

Mercury, Venus, Earth, and Mars are known as the terrestrial planets. In comparison to the outer planets, they are small in size, made of denser materials, and lack a huge numbers of moons. Even though they share these common traits, they are still very different from each other. Mercury is the closest planet to the sun, yet its surface is either extremely hot or extremely cold due to the slow rotation of the planet on it's axis and the lack of atmosphere. It is also unique in that it's core is…

Earth’s Atmosphere By Ikotun Oluwatoke Environmental science 2000 Student number: 7733112 Introduction Human activities has caused increase of dangerous air pollutant and climate change which has led to serious health illness, the increase in population is directly proportional to the increase in human sources of pollution. In the early model of Earth’s atmosphere, oxygen was a minor component of the Earth’s atmosphere and so many theories were made up for why this was so. However, as…

that acts of kindness do not demand anything in return and that they benefit both parties. Without the Sun, the Earth and everything on Earth would cease to exist; the Sun is sustaining life. Nonetheless, the Sun doesn’t require the Earth to survive so it may seem outlandish for it to play such a large role in the well being of an insignificant planet. The benefits of the Sun to Earth are evident but what is much more imperceptible are the positive ramifications that are experienced by the Sun.…

Earth is a very delicate planet and it is at the mercy of humans. Humans have been causing disruptions in the Earth’s atmosphere for far too long now and it is time to finally make a change. Global warming has been a huge debate for a long time, but now it is time to realize that it is real, and it can destroy many living things on this planet, including us. This memo is to show the problems and some ideas for improvements to help the environment. What are the problems? One huge issue is global…

currently a well-known Canadian Environmentalism; however, he goes about his environmental passions in a unique way. In “It Always Costs” David explains his reasoning for going into broadcasting, in order to effectively express his concerns for our Mother Earth. Through speaking to the public, he hopes to gain a broader audience and expand perspectives on the current issues facing our world. Although Suzuki reveals multiple concerns within his past studies, when it comes to “It Always Costs” he…

environment, the slash and burn agriculture (the razing of forests with fire for farming) creates land free from weeds, and the ash from the trees provides nutrients for crops.” That is to say, if more trees are getting burnt down for farming, our earth will have more…

Characteristics of Sun As matter of fact, our solar system is composed of the Sun and all things which orbit around it in the nature of the Earth, the other eight planets, asteroids, and also comets. Even though the sun is a normal star but it is much closer to us compared to any other star. By studying the sun, we do notonly acquire about stars and galaxies but in the end, we can also learn more about the universe. Another significance of learning more about the sun is we will apprehend more…

The Sun is an enormous, extraterrestrial body that is many times larger than Earth. Many scientists have referred to it as a massive nuclear reactor that burns numerous amounts of hydrogen; and just like an actual nuclear reactor, hydrogen is the essential fuel in nuclear fusion reactions. The hydrogen in these fusion reactions fuse together to form beryllium, helium, and lithium atoms. “The temperature on the surface of the Sun is approximately six thousand degrees Celsius. While at its core,…

1 million of earths mass to be equivalent of the sun. There very little that could be more powerful as the sun. It contains two main things that produce heat as it does today. Those two things are hydrogen and helium. The temperature it normally stays at is around 15 million degrees celsius. Which is enough heat to reach to are planet earth this day. The sun tends to be a bomb with this much material packed into one star. But yet gravity keeps it together. As time goes the earth will be…
