Transcript TOPICS TO BE COVERED

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

 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
Physical weathering, also known as mechanical
weathering, is the class of processes that causes
the disintegration of rocks without chemical
change.
 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
 Erosion is the term associated with the
physical action friction by several
agencies like wind, water etc.
 Erosion by water
 Erosion by wind
 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
 The wind erosion process detaches soil
particles from the land surface and
transports them by wind.
