Shake Shake Shake Our Earth

Shake Shake Shake Our EarthLayers:LithosphereActivities:, BrainPop Video, Music VideosTopics: Continental Drift, Faults, Plate Tectonic, Earthquakes, Earth Structure, Seismic Waves.Earth has four basic layers: inner Core, outer core, mantle and crust. Crust is the layer that we live on. This is the hard layer under grass, and water. It is thick in the continent and in the ocean basins. Mantle is made up of mixture of element. It is deep and massive, goes down from the bottom of the crust. The upper mantle is soft and plastic which allow the plates move around. The lower mantle is solid and hot. The center of the earth is core, outer core and inner core. Outer core made of molten iron and nickel. It is liquid layer with 2,300 Km thick. Inner core is 5,100 Km below the surface. Inner core is a hard ball that made of iron. Asthenosphere activities topics-  Asthenosphere

- Topics: Convection Currents
- he mantle is very hot  and is under great pressure. Convection Cuurents move the earth’s plates. Heat from the outer core cause the magma go up and then it go down again when it reaches the cooler crust creating circle.z
MantleActivities: Photographic evidenceTopics: Plate boundaries, Subduction Zone, Fault zone, Hot spot, Tsunami, Earthquake When plates moving, they can slide apart, collide together or horizontally past each other. The boundaries where plates meet may cause volcanoes, mountains, trenches and earthquakes. They are also called faults. Because plates build up pressure in side rocks, rocks broke up and shift to release the pressure. This is earthquake. Earthquake has three types of waves. They are P-wave, S-wave and L-wave. earthquake can bring huge damage to the environment. It is serious disaster.2. Critical Thinking Question I agree with the theory of plate tectonics. If we put all continents together, they are look like puzzle.. After millions years, Earth’s crust broke up in large pieces called plates. Plates are moving few centimeters away from each year. Scientists found that rocks record and fossils in continents have similarity. That’s why there are seven continents on the earth.Because of the convection current, the heat in the mantle forces plates are moving on top of the mantle in different direction. This causes the ocean floor spreading from the center.3. Reflection1. What did you enjoy most about this project and why?I most enjoy is can chose activities on each types.2. What was most challenging for you during this project and why?Find the project on time.3. What new skills did you learn from doing this project?I learned to make video.4. Is there anything that you could have done to improve any of your work? Explain.
I could come to present my project.
