vapor, Carbon dioxide (CO2), Methane (CH4), and Nitrous Oxide (N2O), have always been in the atmosphere. Without these gases, the Earth would not be habitable to most life because of the fluctuations of the amount of heat given off from sun (-18°C)! We need these greenhouse gases to capture the sun’s rays in periods of low radiation and heat the planet to sustain life on Earth. Greenhouse gases reflects infrared light back to the Earth’s surface where more heat absorption takes place, making the planet

Is There Life Off Earth Wiki Final Project My original opinion was that there is life off-earth. I justified this opinion with two great articles that took relatively unbiased stances on the subject of life off-earth. Both articles had great arguments for and against life off-earth. What I specifically used to justify my opinion was two things: Both articles talk about planets having similar features to earth. This would mean that they could (theoretically) hold and nurture life, as our planet did

average person believes that seasons are a result of the sun 's rotation around the Earth, but there is much more involved than what people assume. The Earth 's seasons are affected by many different factors such as the influence of different hemispheres, rotation of the sun, and greenhouse gases. They will also continue to change over time. The climate has a huge effect on the seasons and the population. The Earth 's seasons end up having a ripple effect on people, plants, animals, and agriculture

Plate tectonics occur not only just on Earth, but on other planets in the galaxy as well, such as Venus, Mars, and ancient Mercury. Since there are several planets in the Milky Way that have plate tectonics, it is questionable about if size is a key factor in the likelihood of tectonics on foreign planets. Vol-canoes, mountains, ocean ridges, earthquakes, and tsunamis all would not be possible without the movement of the Earth’s tectonic plates. Dependent upon heat for movement, tectonic plates are

Sometimes the Earth is Cruel Essay Sometimes the Earth is more cool than you can imagine. After the high 80 earthquake on January 12th, 2010, Leonard Pitts, and award-winning journalist, wrote a powerful article to show the Earth's “cruelty” and the tragedy that struck Haiti. The article “ Sometimes the Earth is Cruel” portrays the Haitian people's response to an earthquake by using figurative language, a strong theme, and a powerful message. Throughout the article a strong theme of persistence is

have obvious alignments. They’re either on the side of the heroic protagonist, or the villainous antagonist, but in the 1951 film The Day the Earth Stood Still, directed by Robert Wise, the sides take on more ambiguous roles. Set in the Cold War era America, the movie opens with the arrival of an alien, Klaatu. His mission is to alert the entirety of the Earth that the rest of the universe has created a peaceful society and that if they ever leave the confines or Earth’s atmosphere with the intuition

problem that faces Earth today is pollution. There are a bunch types of pollution on planet Earth but by far air pollution is the deadliest. Air pollution can inhibit the breathing of living organisms. Many major companies including Exxonmobil and Bp who are leading the air pollution race with a Exxonmobil averaging 39 million tons of emissions. These emissions are released into the air by the process of making gasoline and chemicals. The second biggest environmental problem Earth faces each year is

climate change has affected the planet in the past there were many problems to the earth millions of years ago. There were five major ice ages from the longest and first scientists believe occurred was two point four to two point one billion years ago during the early Proterozoic Eon there was an ice age formed and it was the Huronian. The second ice age was the cryogenian and it has been known that it produced a snowball earth in which permanent sea ice extended to or very near the earth's equator; this

the Earth beneath our feet befuddled scientists. They understood that there was a fiery chasm constantly spewing molten lava. But what was underneath all of that magma, was there anything else? It would take thousands of years before a scientist could create a viable hypothesis for the core of the Earth. According to Edmund Mathez of the American Museum of Natural history, Inge Lehman, a Danish seismologist, published a paper in 1936 that suggested there was a solid inner core to the Earth, as well

Back when Earth was still a mysterious place, when giant beasts roamed the land and serpents ruled the sea, Mother Earth was in turmoil. Her children and Father Sea`s children, the Humans, waged war upon each other. Her offspring were full of corruption, lies, and bloodlust. They would attack villages and loot, murder, and do other unspeakable crimes. Some even discovered the Dark Arts, and using this to their advantage, would control other humans and summon strange demons from the sky. The demons
