Lesson : Not my creation but unsure of the innovative source Task 1 - Using this and the images and text below, copy and paste the correct images and statements into the correct place in the table. Some pyroclastic flows are over 900 degrees F. The Richter scale is a measure of the strength and length of time that earthquake lasts. . Because of their speed they arrive at the surface first and are also called P Primary waves. A strike-slip boundary occurs where two plates are sliding past each other in opposite directions. A convergent boundary occurs where two plates collide.
Write definitions in your own word for the following terms: a - A volcano that is currently erupting or has erupted in recorded time. The of very hot steam, gas, and. Task 2 - Using the large plate map image below click to enlarge , complete your plate map The first one is easier and the second is a little bit more testing as both maps are different views of the world. Students are provided with a world map, with latitude and longitude coordinates around the map. Tsunamis are caused by 1 an earthquake 2 an underwater landslide 3 or a volcanic.
Add plate boundaries black lines and the names of the plates. Teacher Resource: for alternative lesson. Students should be instructed to use a different colour for earthquakes and volcanoes. Check the work with your teacher and then print out a copy of your sheet for your folder. Objective: To find out what happens under the ground when two plates meet.
Sometimes one plate is driven under the other, other times the two plates force themselves up into high mountains. The evidence is very different, but yet when you plot the data a picture emerges. Found worksheet you are looking for? Describe in your own words what a is. By comparing the marked locations on the chart with their completed puzzles, students are able to determine the geologic relationship. They hit the surface with a rolling, up and down motion. Task 2 - Use resource 1 to introduce tasks to students but don't show the last slide. Complete for 30 students working in pairs.
How is a strike-slip boundary different from a convergent and divergent boundary? There are two kinds of surface waves Love and Rayleigh waves. They are also provided with a table, which has the coordinates of earthquakes and volcanoes. They hit the surface with a pounding or jackhammer motion. What are the differences between compression, shear, and surface waves? Each group should collect between 35-40 data points. Plenary - on the key terms covered. In previous lessons, students will have learnt about continental drift, plate tectonics, and the different types of movements at plate boundaries.
Compression waves are the fastest waves produced from an earthquake. It is like a tear in the crust of the Earth. Surface waves are the last waves to strike the surface and are confined to the upper layers of the Earth. The are the slowest waves and cause the most damage. Objective: To find if Earth has always looked the same and to find out what continental drift means. Neither Achieve nor the lead states and partners that developed the Next Generation Science Standards were involved in the production of this product, and do not endorse it. The map can be projected on the board, and as a class the first few examples can be plotted together.
After you have found 10 data points, share the information with the rest of your lab group. Then, using degrees of latitude and longitude, their own geographic knowledge and a chart of the ocean floor, students identify the locations of recent earthquakes and volcanoes. A divergent boundary occurs where two plates are separating. These waves can be up to 100 feet high when they break on the coastline. These occur at mid-ocean ridges. This is the cooled down layer that has solidified a bit like skin on top of a pan of custard! The two plates are moving in opposite directions causing new crust to be formed.
Evaluate evidence of the past and current movements of continental and oceanic crust and the theory of plate tectonics to explain the ages of crustal rocks. They arrive later and thus called S Secondary waves. Volcanoes provide a location, type of eruption, and type of rocks produced. Use the clues in the description to help you and your completed A3 size plate maps from last lesson see above. How are earthquake waves produced? Analyze and interpret data on the distribution of fossils and rocks, continental shapes, and seafloor structures to provide evidence of the past plate motions.
