  1. 1. it is a hill or mountain where lava pyroclastic materials and gases erupt
  2. 4. It is a process of changing the characteristics of a rock as a result of changes in temperature, pressure, or reactions with hot fluids
  3. 6. internal heat, It fuels the planet’s dynamic processes including plate movements, earthquakes, and volcanism.
  4. 7. rocks, This is a type of rock formed from preexisting rocks and fossils of organisms
  5. 8. When magma rises to the crust it can displace the host or country rock to form structures called?
  6. 11. Refers to transferring of unconsolidated earth’s material via agents like human animal wind and water.
  7. 14. It is a discernible displacement where rocks grind or slide past each other.
  8. 15. plates, These are slabs of the brittle lithosphere which can be able to move due to the plasticity of the underlying asthenosphere
  9. 17. erodibility, It is the vulnerability of soil to erosion caused by rainfall intensity soil properties crop cover and slope.
  10. 18. It is a dynamic planet composed of interacting subsystems, namely: atmosphere, hydrosphere, lithosphere, and the biosphere.
  11. 19. It is the rigid outermost layer of earth that is composed of crust and the uppermost layer of the mantle
  12. 20. It is an aggregate of minerals or minerals which may not contain organic matter.
Down
  1. 2. This is one of the types of mass wasting that have a slow downhill movement.
  2. 3. push, This is a force that causes hotter less dense material to force itself up through a ridge
  3. 5. , It is a process where there is growth in the size of mineral grains of pre-existing materials
  4. 9. Known as radioactive dating of hotspots show age differences based on plate movements.
  5. 10. These are substances that evaporate easily and can exist in gaseous form on the surface of earth
  6. 12. It is the process of breaking down rocks present at earth’s surface.
  7. 13. It occurs along the plate boundaries or margins and sometimes within the plate.
  8. 16. wedging, It is a process that involves repeated cycles of freezing and thawing of ice.
