gr. 7 planet earth

• the molten layer of rock in the earth is called

  Outercore
• scientists that study the earth are called

  geologist
• sediments being transported

  erosion
• first place rocks break below the surface in an earthquake

  focus
• upper part of this layer is solid, lower part of this layer is molten

  mantle
• an idea of something that can't be fully known or seen

  model
• upper mantle and crust

  lithosphere
• process of sediments being deposited, usually at the bottom of an ocean, sea or river

  sedimentation
• device that detect waves of energy in an earthquake

  seismograph
• magnitude of an earthquake is given a number on this

  richter scale
• the point on the surface directly above the first breakage point in an earthquake

  epicentre
• Layer of solid rock beneath the loose rock fragments

  bedrock
• Opening in the Earth's crust through which solid and molten, rock, ash and gases escape.

  volcano
• Solid outer layer of the Earth.

  crust
• Sudden and fast movements of rocks and soil down a slope

  landslides
• Landforms that are created by running water

  fluvial landforms
• Sand, silt mud, or gravel carried on by flowing rivers.

  sediment
• Process that breaks down rocks by moving water, wind, ice or glacial movement.

  weathering
• name of earthquake waves

  seismic waves
• trembling of ground caused by sudden release of energy built up in the earth's crust

  earthquake
• process of sediments being laid down by wind, water or ice

  deposition
• moving mass of ice or snow

  glacier
• Solid layer of Earth that is under great pressure from the other layers.

  innercore
• innercore state

  solid
• crust's state

  solid
• outercore's state

  molten
