  1. 3. is a geophysical theory that explains the origin of the Earth's main magnetic field in terms of a self-exciting (or self-sustaining) dynamo.
  2. 6. believed to be the one responsible for different rock behaviors in the mantle.
  3. 7. largest layer of the earth.
  4. 9. is a low-lying area of land situated between hills or mountains.
  5. 12. are flat and broad land areas that have no great changes in elevation when measured with reference to the mean sea level.
  6. 13. also known as table lands or flat-topped mountains, are portion of lands elevated thousands of feet above their surroundings.
  7. 16. are those that rise higher than the rest of their surroundings.
  8. 17. is a bend in a sinuous watercourse river.
  9. 20. is a predominantly silt-sized sediment formed by the accumulation of windblown dust and a product of glacial activity in an area.
  10. 21. outer solid part of the planet include earth's crust as well as the underlying cool, dense & rigid upper part of the upper mantle.
  11. 22. are formed by the chemical and mechanical action of the wind, word derived from Greek god of the winds, aeolus.
  12. 24. also called fluvioglacial, bodies of water associated to these landforms interacted with glaciers or ice caps.
  13. 25. sometimes called gorge, is a deep ravine between cliffs that is often carved from the landscape by a river, wind or glacier.
  14. 27. is the last & innermost layer which is seperated into liquid outer core & the solid inner core.
  15. 28. also called byland or biland, is a piece of land that projects into a body of water and is connected to the mainland by isthmus.
  16. 29. are defined as the natural physical features on the surface of earth.

  1. 1. is the scientific study of landforms and the processes that shape them.
  2. 2. is detected using a compass.
  3. 4. is typically a low-lying triangular area located at the mouth of the rivers where it meets an ocean, seas or estuaries.
  4. 5. are those underwent sedimentation, erosion or deposition the river bed.
  5. 8. are created from exclusively erosional and weathering activities.
  6. 10. extends from just under the uppermantle to 2,200 km.
  7. 11. outermost layer of earth, thinnest layer as it makes up only 1% of the earth.
  8. 14. are elevated portions of lands that are formed by geologic activities such as faulting.
  9. 15. are high rocky coast that plunge down to the edge of the sea.
  10. 18. is almost similar to mesa as it has a flat-topped hill and steep sides and are formed in arid to semi-arid desert conditions.
  11. 19. seen as higly viscous layer which lies between the crust and the lower mantle.
  12. 23. are landforms that are controlled by geological processes that form them and continually act on them after their formation.
  13. 26. study of the flow of matter primarily in the liquid state under conditions at which they respond with plastic flow rather than deforming elastically in response to an applied force.
