Oh the irony! The planet that lived... well atleast for the moment... If you come up with any more during the course of the lesson please post them!! Right, so the earth is not completely round. Can anyone give me the term that is used to describe its shape? |
*raises her hand* "is is a sphere or a oval? Wait, are you talking about how its rocky or not smooth because of the of the different physical features." *leans back, slightly confused* |
Francis raises her hand, "Oval? Since.. it is not a perfect circle..." |
jenn laughed out loud at francis' answer. she knew she herself wasn't witty. "i once heard earth compared to a basketball" hmph... that's not very good... "e to the arth? a violent sphere of never-ending tectonic activity constantly churning and in rebellion against its inhabitants?" |
[OOC:Unfortunately I have to go for now, feel free to answer the question and keep posting hilarious nicknames, you never know, you could earn more points. I will be back on later, and will be on at all different to make it fairer for people in all timezones, but I should be on a few times a day. See you all later!] |
Zekke pondered on that one for a moment as his mind ran through all the possible terms. Spherical... no... elliptical... errrr maybe... oblong... errr? He raised his hand. "The earth is... oblong, I think? And it takes an elliptical path." |
*raises hand because she actually knows the answer* the earth is oblong-shaped. its circumference around the equater is larger than the circumference along a line of longitude. it is a sort of squashed sphere |
Francis laughs. The idea of a rebellion against its inhabitants is quite witty. Smiling at Jenn, she then turns to the Professor and waits. |

*looks in textbook* "the polar radius of the earth is 6356.9 km while the equatorial radius is 6378.4 km, a difference of 21.5 km. the bulge at the equator is caused by the earth's rotation on it's axis. the northern hemisphere and the south pole (antarctica) are slightly depressed also because of the landmasses there causing a very slight pear shape." |
*laughs* "I've never herd of oblong-shape. It reminds me of that show that use to be on, The Oblongs. Anyways, you might be right *giggles* I just never herd of oblong-shape, its humerous to me. Hey, at least I got spherical. ;) |
sorry nm hold on and ill edit again |
"circle...elipse...oblong....?Hmm..how about 'circlong',or 'circlipse',or maybe 'eblong'?" Ivana said |
::thinks:: "Suppose it's oval, sphere, a bit roundish, it's not really round is it? Oblong? Never heard of that kind of shape....is that really a shape?" |
Serena raised her hand, The Earth's shape is described as a sphere, but it is not perfect. It is about 25 miles (40 km) thicker across the middle than it is from North pole to South pole and is caused by the rotation of the Earth. The Earth is elastic enough to 'deform' under the influence of the spin. It is also described as the Earth's oblateness, which is how much its rounded shape flattens at the poles and widens at the equator. I also found earth has been described as a somewhat pear shaped ellipsoid, with a slightly larger southern hemisphere than northern hemisphere. Even others describe it as ovoid, meaning shaped like an egg. Hmmmm.... Some other earth terms I found: (Not funny) Greenhouse Planet Satellite (because it orbits the Sun) (Funny) Hollow Earth... for those who want to journey to the center of the earth! (Trip advertised... 'Voyage to Our Hollow Earth') (Most Funny or Strange) Hummocky.... which means uneven, lumpy terrain. |
Meghan giggles at all the funny answers and writes some down. |
*Selena raises her hand* Earth is pear shaped. Because the Earth rotates it causes it to have a bulge in the middle. |
These really arent funny, but they are true. Earth is the contridictory planet. its sunny, rainy, cold, warm, etc. all at the same time and in different places. Its also the outcast according to other planets because its the only planet that hasnt killed its inhabitants but will be killed by them. |

*Hannah raised her hand* the green planet. Hannah said |
*Julia quickly copies down some of the things others have said. She looks back up at the professor. She thinks about what shape the earth is. Julia raises her hand politely.* "Through a long history, the 'figure of the earth' was thought to be from flat to like a spheric figure. I think it is more like a sphere shape though, because the earth is round. The earth isn't flat, and since it is round also, the earth is most likely a spheric figure." *She puts her hand down and smiles up at the professor.* |
*going back to the question of nicknames for earth, Em raises her hand* "The Mental Institution of the Universe." *Em giggles to herself, hoping others might find it slightly funny too* "Another name could be Gaia, after the mythological name for Mother Earth." |
Kali raised her hand, "It's not that funny, but one of the terms I heard to describe the earth is Spaceship Earth because Earth was like a spaceship with limited amounts of supplies in space," she paused ,"The earth is almost spherical except it's squashed. So it's similar to a squashed sphere." |
Lee raised his hand we could call earth, mother earth or the planet of major destruction or the place who tries to make peace but it doesnt work out for them Lee smiled there a bit long but its best i could think off, i take the earth as a rocky circle with many circumferences, starting with the earths crust and then the other layers of lava underneath, and then the spherical shape of the earths core. Lee copied down the rest of his notes and waited for a response from the professor |

Thats what I was looking for! The term is oblate. Well done, 5 points!! Quote:

Thats right, the two diametres of earth differ by about 42km, giving it a slight squashed appearance. Can anyone answer this... Earth is the _____ planet in distance from the sun, and the ____ largest in diametre. |
