If a substantial amount of calcium is discovered, coronary artery disease may be likely. A CT coronary angiogram, in which you receive a contrast dye injected intravenously during a CT scan, also can generate images of your heart arteries.
At converging plate boundaries, two situations are possible. First, both volcanoes and earthquakes form where one plate sinks under the other. This process, called subduction, takes place because one plate is denser than the other. The denser plate, which invariably has oceanic crust on its top, does the sinking. Second, only earthquakes occur when two plates collide (obduct), building a mountain range.
Earthquakes Date Class 0 LESSON 1 A. B. What are earthquakes? are the vibrations in the ground that result from movement along breaks in Earth's lithosphere. 2. The forces that move breaks in the lithosphere. Where do earthquakes occur? 1. Most earthquakes occur along active also push and pull rocks along . These areas are plate boundaries, boundaries, generally in the middle of oceans or along the edges of a. Deep earthquakes occur along where a denser oceanic plate subducts into the mantle. b.
