Across
  1. 3. the crust and rigid upper mantle, which is divided into slow-moving tectonic plates
  2. 5. a long, deep depression in the ocean floor, formed where one plate subducts beneath another at a convergent plate boundary
  3. 6. a geological process at convergent boundaries where one tectonic plate sinks beneath another plate
  4. 7. a crack in a large section of rock where the two sides have slid past one another
  5. 8. an unusually hot part of the Earth's mantle, which often results in magma rising up through the crust to form a volcano; as a tectonic plate moves slowly over a hotspot, a chain of volcanoes can form
  6. 9. a zone of intense volcanic and earthquake activity that surrounds the Pacific Ocean
Down
  1. 1. a section of the Earth's crust and upper mantle; the slow movement of tectonic plates around the surface of the planet is responsible for continental drift and most earthquakes and volcanoes
  2. 2. the starting point of an earthquake
  3. 3. hot liquid rock that erupts from a volcano and cools to form an igneous rock
  4. 4. the point on the Earth's surface directly above the starting point of an earthquake
