Earthquakes

Q.1 Where do most of the earthquakes tend to happen?
A.1 (A)Most earthquakes tend to happen mostly in the northern and western part of the world.
(B)There have been at least several dozen earthquakes that have happened in Alaska lately.
Q.2 Why do you think that is?
A.2 I think this is because the ice caps are melting and it causes cracking in the ground and plus the Alaska's plate is probably slowly drifting away from America. Also it could be that other continents are moving in different directions constantly causing plates to pull apart or to crash into each other.
Q.3 What is this area called?
A.3 The ring of fire
Q.4 (A)Where is the earthquake closest to Manitou Springs?(B)What are the details of this earthquake? (C)Would people be able to feel this earthquake? (D)About how much more ground shaking would occur for this magnitude earthquake compared to a magnitude 1 earthquake? (E)About how much greater is the energy released with this earthquake compared to the energy of a magnitude 1 earthquake?
A.4 (A)The latest and closest earth quake that was near Manitou Springs Middle School happened at Thursday, January 15, 2009 at 10:02 almost on the border of Colorado and Wyoming.(B) It's exact location was at 40.953°N, 106.930°W and it was
5km deep and it traveled 31km from Grand Encampment, WY. Then 32km from Riverside, WY
Then 52km from Dixon, WY. Also 162km from Fort Collins, CO. Finally 215km from Denver, CO. (C)People probably wouldn't mostly likely feel this earthquake because it was really small so small you probably would bearly and probably feel it even if you were right by it especialy because we are use to them happening all the time we get use to them. (D) This earthquake would probably almost 3 times worse of an magnitude 1 earthquake because it's magnitude marked the scale at 3.2 but that isn't to strong of a earthquake so the shakeing would be a little worse but not by much. (E)I would say the energy realeased from this earthquake would be 3 times greater than a earthquake of a magnitude 1 earthquake because it's rated a little higher than 3 times as much.
Q.5 Choose one earthquake that has happened in the last seven days. You will be researching that earthquake. Tell me all about it. Are earthquakes common in this area? Include at least one picture, preferably of the earthquake, but if you can’t find one include one of the area.
A.5 I chose an earthquake in Chiapas,Mexico that happened Saturday, January 17, 2009 at 02:57pm.(15.805°N, 92.482°W) It was a wopping 176.4 km deep.Earthqaukes are somewhat common in this area. This earthquake was a perty decent size of a earthquake. This earthquake was a shocker to some people especialy to tourist because this is a big tourist attraction because of it's natural beauty. Thankfuly no one was killed but it did some damage. This earthquake ruined some locals homes but the worst thing about it was the shock in the tourist because it ended their vacation a little early. (distances-60 km SW of Comitan, Chiapas, Mexico 100 km NNW of Tapachula, Chiapas, Mexico250 km WNW of GUATEMALA CITY, Guatemala 810 km ESE of MEXICO CITY, D.F., Mexico)


Q.6 How can people protect themselves from the dangers of earthquakes?
A.6 Their are alot of opinions of what you should do during a earthquake. But the best thing to do is to get outside if you get caught in the middle of one, but by chace if you can't make it outside stand under the most sturdiest place in your house which is ussaly under the door way. But the most important thing you can do to protect yourself from a earthquake is to be pre-paired for it. Stock up on non-parishable foods and drinks and to also have a first aid-kit handy.

Questions

Q.1 How have geologists learned about Earth’s inner structure?
A.1 Geologist learned about Earth's inner structure by the invention and use of electromagnetic waves and radiation waves.
Q.2 How is Earth’s interior like an apple?
A.2 It's like an apple because the outer part is soft and the closer you get to the core the tougher it gets.
Q.3 What are the layers of the Earth?
A.3 The layers of earth are the lithosphere, asthenosphere, and the lower mantle.
Q.4 What are the characteristics of Earth’s crust, mantle, and core?
A.4 The crust is soft dirt filled with rocks, the mantle is tougher than the crust ad has dirt and rocks just like the crust but it's warmer because it's closer to the core, and lastly you have the core that is just hot liquid metal, iron and nickle.
Q.5 How is heat transferred?
A.5 Heat can be transfered in three diffrent ways. It can be transfered in radiation which is of energy from empty space. Then their is conduction which transfers heat with in a material. Lastly their is convection which transfers heat through liquid.
Q.6 What causes convection currents?
A.6 Convection currents is caused by cooler dense air sinking and warm less densed air rising.
Q.7 What causes convection currents in Earth’s mantle?
A.7 Convection currents in earth's mantle is caused by the heat from the core an the mantle it's self.
Q.8 What was Alfred Wegener’s hypothesis about the continents?
A.8 Alfred Wegener’s hypothesis was that earth's continets slowly move.
Q.9 What evidence supported Wegener’s hypothesis?
A.9 The evidence that supported Wegener’s hypothesis was that all the continets looked like they all fit together at one time, also evidence of vegitation where they couldn't grow, and lastly the founding of fossils of the same animals all over the country where they couldn't migrate back then.
Q.10 Why was Wegener’s hypothesis rejected by most scientists of his day?
A.10 It was rejected because he didn't have any phisical proof to back up his hypothisis until we advanced in our tecnology to scan the ocean and prove his theriory.
Q.11 How does sea-floor spreading provide a way for continents to move?
A.11 It causes continents to move because it drifts with the ocean causing it be pushed and drags the plate tectonics.
Q.12 What is the evidence for sea-floor spreading?
A.12 The evidence for sea-floor spreading is it's eruptions of molten material, magnetic stripes in the ocean floor, and the age of the material.
Q.13 What happens at deep-ocean trenches and why?
A.13 Deep-ocean trenches expand it's size causing oceanic crust to bend downwards.
Q.14 What is the Mid-Atlantic Ridge?
A.14 Mid-Atlantic Ridge is a mountain under water that has been made over the years by the movement of plate tectonics.
Q.15 What is the theory of plate tectonics?
A.15 The theory of plate tectonics is that pieces of Earth's lithosphere are in slow constant motion driven by convection currents in the mantle causing earth's structure to change over time.
Q.16 What are the three types of plate boundaries and what are their characteristics?
A.16 The three types of boundaries are the Divergent Boundaries which is where two plates move apart from each other. Then there is the Convergent Boundarys which is where two plates come together. Finally you got the Transform Boundaries which is a place where two plates slip past each other moving in opposite directions.
