Layers of the Earth Vocabulary crossword puzzle
Across
  1. a mechanism that helps power plate tectonics. The cooling, dense oceanic slab sinks at a subduction zone and pulls the rest of the plate with it.
  2. Type of plate boundary where the plates move apart as magma rises to the surface from the asthenosphere.Ex: Mid-ocean ridges; mid-atlantic ridge, East Africa Rift
  3. Type of plate boundary where plates move toward each other. One plate sinks beneath another along a subduction zone. Descending plate melts, gnerating magma. No subduction zone for two continental plates colliding. Ex: Chile and the West coast of South America, Japan
  4. the record of the orientation of the magnetic poles with respect to the rock being studied - Remnant magnetism in ancient rocks
  5. This layer of the mantle makes up the greatest volume of the earth. It is solid.
  6. Middle layer of the mantle. This layer is “plastic” – the rock is soft and weak, so it is in this layer that the heat convection currents can flow. This powers plate tectonics.
  7. the outermost layer of the earth which makes up the ocean floor. Thin and dense enough to be subducted.
  8. This is solid iron-nickel material
  9. a mechanism that helps power plate tectonics. The creation of new oceanic crust at divergent margins (mid-ocean ridges) pushes the plates away from each other.
Down
  1. theory that the lithosphere is divided into rigid plates that move over the asthenosphere. Movement is on a global scale, resulting in continental drift and changing the shape, size and location of continents and ocean basins.
  2. Crust plus Upper mantle. This makes up the tectonic plates
  3. the outermost layer of the earth. Thick crust, less dense so may not be subducted.
  4. the magnetic and geographic north and south poles are located at approximately the same place. This is the current day orientation of the magnetic field.
  5. Type of plate boundary where the plates slide sideways past each other. Example is the San Andreas Fault.
  6. An idea before plate tectonics that showed that the continents had all fit together into a giant supercontinent (Pangaea) at some point in the past. Continents had somehow moved through the oceans to their present position. Did not provide a mechanism for movement of the continents.
  7. the idea that new oceanic crust is created at divergent plate margins. The ocean crust and continental crust move together as a unit.
  8. Solid mantle material
  9. the magentic north and south poles reverse positions. Magnetic north pole coincides with geographic south pole

18 Clues: Solid mantle material • This is solid iron-nickel material • Crust plus Upper mantle. This makes up the tectonic plates • This layer of the mantle makes up the greatest volume of the earth.

  1. Molten rock containing liquids, crystals, and dissolved gases that forms within the upper part of the Earth's mantle and crust. When erupted onto the Earth's surface, it is called lava.
  2. A depression in the earths crust
  3. A deep depression in the ocean floor caused by the convergence of plates and the resulting subduction of one plate
  4. A tectonic process that results when plates converge and one plate forces the other down into Earth's mantle. As a result, the subducted plate eventually undergoes partial melting
  5. The term used for magma once it has erupted onto the Earth's surface.
  6. An area of rock that has been bent by stress.
  7. An abrupt movement of soil and bedrock downhill in response to gravity. Landslides can be triggered by an earthquake or other natural causes. Undersea landslides can cause tsunamis.
  8. A form of stress resulting from equal and opposite forces that do not act along the same line. If a thick, hard-bound book is lying flat and one pushes the front cover from the side so that the covers and pages are no longer perfectly aligned, this is an example of shear.
  9. The uppermost division of the solid earth, representing less than 1% of its volume and varying in depth from 3-37 mi.(5-60 km). Below the crust is the mantle.
  10. The center of Earth, an area constituting about 16% of the planet's volume and 32% of its mass.

  5. One or a series of huge sea waves caused by earthquakes or other large-scale disturbance of the ocean floor. (Referred to incorrectly by many as a tidal wave, but these waves have nothing to do with tides.) The word tsunami is Japanese, meaning "harbor wave."
  6. The flowing mixture of water and debris (intermediate between a volcanic avalanche and a water flood) that forms on the slopes of a volcano.
  7. The theory that the configuration of Earth's continents was once different than it is today; that some of the individual landmasses of today once were joined in other continental forms; and that these landmasses later separated and moved to their present locations.
  8. A vent (opening) in the surface of the Earth through which magma erupts; it is also the landform that is constructed by the erupted material.
  9. An earthquake which follows a larger earthquake or main shock and originates in or near the rupture zone of the larger earthquake. Generally, major earthquakes are followed by a larger number of aftershocks, decreasing in frequency with time.
  10. In general terms, any attempt to deform a solid. Types of stress include-tension, compression, and shear. More specifically, stress is the ratio of force to unit area F/A, where F is force and A area. A tectonic process that results when plates converge and one plate forces the other down into Earth's mantle. As a result, the subducted plate eventually undergoes partial melting
