5/1/2023 0 Comments Convergent plate boundary![]() With a ruler, carefully measure the distance between locations on the map to the nearest millimetre if you use S.I. (a) First, determine the distance between each pair of locations listed on the chart. ![]() Complete the chart on the following page: If subduction is taking place, clearly show which plate is subducting beneath the other.ġ. Use the “side view” drawings and Figure 2 for reference, and use arrows to indicate the relative direction of plate motion. In the space below, draw an approximate continuous cross-section (“side view”) of the ocean basin from Point “A” to Point “B” (from lower left to the upper right). With the number “6” label this volcano.ī) With a 2-centimetre (about I-inch) long arrow extending from this volcano, indicate the direction in which you would expect to find progressively older extinct volcanoes left by the hot spot.ħ. a) Assume that only one of the volcanoes on the map is associated with a hot spot. With the number “5” label all plate boundaries where oceanic trenches should be found.Ħ. (a) With the number “4” indicate the most likely location on the map of a volcanic island arc.ĥ. a) With the number “3” indicates the most likely location on the map of a major volcanic mountain range similar to the Andes in South America.Ĥ. (c) What evidence shown 011 the map indicates that this type of boundary is present?ģ. (b) What type of plate boundary is this? _ _ (a) With the number “2” indicates the most likely location on the map or a midocean ridge (such as the Mid-Atlantic Ridge). (b) How many of the plates on the map consist entirely of the ocean floor(or the ocean floor with islands)?Ģ. (a) How many different plates (not boundaries) are clearly shown on the map? _ _ When asked to cite evidence to support your answers, only cite evidence that you can see on this map.ġ. Arrows indicate the direction of plate movement.Īfter drawing in the plate boundaries using the appropriate symbols on the tectonic map below, answer the questions on the following page. ![]() Both the map symbols and a side view of the circumstance they represent, are shown below. Use the following symbols to indicate the extent of all plate boundaries. (c) Volcanic activity may be associated with subduction, spreading centres, or hot spots. Ocean floor is being created at a midocean ridge. (b) The age pattern of volcanic ocean floor rocks suggests the location where the new For example, subduction produces a pattern of deeper and deeper earthquakes as one plate plunges below the other. CLICK HERE TO PLACE AN ORDERĬlues include: (a) The pattern of earthquakes. If you liked this video, please share it on Facebook and Twitter and subscribe to our YouTube Channel.The first step of the exercise is to draw in the approximate plate boundaries as indicated by the tectonic activity on the map. And big thanks to Libby Schirtzinger and DePaul Cristo Rey High School for letting us borrow their classroom. We couldn’t have filmed the clips in the German Alps without Mary Ellen Finnegan and Grace Cook. In this first video, we explain how mountains are formed by convergent plate boundaries.īig shout outs go to Michael Clouse who directed the video and created the animations. Today Science Over Everything has published our first of what will be many videos explaining everyday science concepts. It’s been a lot of hard work, but it’s finally here. Construct an explanation based on evidence for how geoscience processes have changed Earth’s surface at varying times and spatial scales. Key Vocabulary: Convergent, plate tectonics, convection current, density, mountains, subduction, uplift, magma
