4. Physical Geology is a introducing for students will learn about plate tectonics, earthquakes, volcanoes, weathering, erosion, and about Earth's resources.

5. Plate tectonics is a knowledge of the interior parts of earth, it is understood that the uppermost part of earth. Due to very high difference of temperature and pressure ther lower part is floating on the outer core.

7. a mountain or hill, typically conical, having a crater or vent through which lava, rock fragments, hot vapour and gas are have been erupted from the earth's crust.

9. An earthquake is the result of a sudden release of energy in the Earth's crust that creates seismic waves. The seismicity activity of an area refers to the frequency, type and size of earthquakes experienced over a period of time.

11. Weathering is the breaking down of rocks, soil and minerals as well as artificial materials through contact with the Earth’s atmosphere, and waters. Physical(Mechanical) Weathering Chemical Weathering

12. Physical weathering, also known as mechanical weathering, is the class of processes that causes the disintegration of rocks without chemical change.

13. Chemical weathering includes changes in chemical composition of rock due to chemical reaction happening due to surrounding atmosphere conditions this includes temperature, pressure etc. » Hydrolysis » Oxidation » Carbonation

15. Erosion is the term associated with the physical action friction by several agencies like wind, water etc. Erosion by water Erosion by wind

16. Water erosion is the detachment and removal of soil material by water. The process may be natural or accelerated by human activity. Land Slides Mud Slides

17. The wind erosion process detaches soil particles from the land surface and transports them by wind.
