  1. 3. Laying down of sediments carried by moving agents in the river, mud, or shoreline and the like.
  2. 4. A process in which sedimentary rock and igneous rocks are exposed to heat and pressure but not melted this causes changed into another kind of rock called metamorphic.
  3. 8. Outer solid part of the earth including the crust as well as the upper mantle.
  4. 11. A term used for a very large group of minerals which are extremely abundant on Earth.
  5. 13. The model to represent the processes of transformation of rocks from one form to another.
  6. 18. A process in which metamorphic rock is subject to extreme heat and pressure and turns into magma.
  7. 20. also known as rock salt.
  8. 22. Source of the earth’s internal heat.
  9. 23. Usually formed deep within the Earth, during a process such as mountain building.
  10. 24. Segregated into a series of concentric layers of differing composition and density.
  11. 25. Worn away soil and rock particles by the moving agents such as wind, water or ice and gravity elsewhere.
  12. 27. Magma cools fast in the surface of the earth to form extrusive rock or plutonic.
  13. 29. Hardest natural substance on Earth.
  14. 30. Tendency of minerals to break along flat planar surfaces into geometries that are determined by their crystal structure.

  1. 1. It is formed when sediments get packed together.
  2. 2. An aggregate of one or more minerals.
  3. 5. Compounds of metallic cations and oxygen.
  4. 6. Naturally-formed solid element or compound whose atoms and molecules are bound together in a definite orderly arrangement to form crystals.
  5. 7. Magma cools slowly underground of the earth to form igneous rock called intrusive or plutonic.
  6. 9. The sediments are move along by the moving agents like gravity, rainwater and wind.
  7. 10. Highly viscous, hotter and ductile region of the upper mantle that is involved in plate tectonic movements. It has the characteristic of a plastic solid.
  8. 12. Travel through the inner layers of the earth.
  9. 14. A rock composed of generally large, sharp fragments cemented together.
  10. 15. The most common element in the crust.
  11. 16. “rocks of fire”
  12. 17. Refers to the layers of arrangement of minerals.
  13. 19. Breaking down of rock in the lithosphere by the of action of weathering agents such as rainwater, heat and temperature and other biological agents.
  14. 21. Outermost and the thinnest layer of the earth. It is where the most earthquakes happened.
  15. 26. Travel only on the surface
  16. 28. The semi-solid, rocky, hot, and the thickest or largest layer of the earth.
