The South American Plate are those which subducts beneath the Sandwich plate and which leads to the formation of Sandwich Islands Volcanic arc.
at the south sandwich islands, the _________ plate is subducting beneath the sandwich plate
what is a subducting plate involved in the formation of volcanoes of the Philippine islands
i need help with questions Plate Tectonics Type "Ascension Island" into the search bar, zoom out until you can see the plate boundary (mid ocean ridge) and the coast of Africa, Sketch this boundary below (sketch the view you have on your monitor). Indicate with arrows the relative plate motion. Name and label the plates on your diagram. Name and label the plates on your diagram. What type of plate boundary is this? What type of crust is here? If...

Volcanic Hotspots and Seafloor Spreading The figure below is a map of the volcanic islands and seamounts (submerged volcanoes) that form the Hawaiian Islands and the Hawaiian-Emperor Chain. These were formed by a "hot spot" - a relatively stationary hot plume that rises through the earth's mantle and melts part of the overriding plate. Table 1 shows a selection of some of these volcanoes with regard to their age and distance from the active hot spot location. The change in...
Consider the age of the various Hawaiian Islands given below in millions of years. Remember, the formation of the Hawaiian Islands reflects: 1) the movement of the Pacific plate, and 2) stationary volcanic hotspot activity over time. Which direction is the Pacific plate currently moving? Maps are plan or bird's eye views of the earth's surface. Here, the top of the figure is north, and the bottom of the figure is south. The left side of the figure is west,...
volcano islands that form over mantle plumes, such as the Hawaiian chain , are home to some of Earth's largest volcanoes . However , several volcanoes on Mars are gigantic compared to any on Earth. what does this difference tell us about the role of plate motion in shaping the Martian surface?
Los Angeles is presently 550 km south of San Francisco, but is on a plate moving northward relative to San Francisco. If the 5.10 cm/yr velocity continues, how many years will it take before Los Angeles has moved up to San Francisco?
13) A robot stands on a large paved area. Beneath its feet is line that runs 39.96621 norh of east. As per its instructions it moves 11.29988° west of north for 10m. It then moved 4.61685° south of east until it reached the line. It then stopped. How far was the robot from its original position? (Hint: Tilt the coordinate system.)
