actually thanks for the slideshare !!!!! i took a little help from yhis website so i log in to this to help others

13. HOW DOES EARTHQUAKE OCCUR
DUE TO THE PLATES

14. VOLCANO

15.  A volcano is an opening, or rupture, in a
planet's surface or crust, which allows
hot magma, volcanic ash and gases to escape
from the magma chamber below the surface.

16.  Deep below the Earth's crust, the
temperatures and
pressures are great enough to melt rock.
When this molten
rock blasts to the surface, the result is a
volcano - and for
the inhabitants of the place, it's as if Hell
has been let loose.

17.  Why doVolcanoes occur?
 Volcanoes occur when the Earth's plates pull apart causing
magma to rise to the surface.Volcanoes can also occur over
hotspots and where one plate dives beneath another,
forcing magma to rise to the surface. Plates diving under
one another is known as subduction.
 Where doVolcanoes occur?
 Volcanoes usually occur on the edges of plates, similar to
where earthquakes occur. A lot of volcanoes occur in the
area around the edge of the Pacific ocean called the Pacific
Ring of Fire.Volcanoes can also occur in the middle of
plates, in hotspots. One such hotspot has formed the
Hawaiian islands chain. As the earth rotated, it passed over
the hotspot and new islands were formed.

18. LANDSLIDES

19.  What are landslides and how do they occur?
 Landslides have always existed on our planet.
Generally classified as mass movements of rock,
debris, and soil down a slope of land. While
landslides are a naturally occurring
environmental hazard they have recently
increased in frequency in certain areas due to
human activity. Although there are many
different causes of landslides, they all have two
things in common.They are the results of the
failure of the soil and rock materials that make
up the hill-slope and they are driven by gravity."

21. WORK OF A RIVER

22. WEATHERING
 Weathering is the breaking down
of rocks, soils and minerals as well as artificial
materials through contact with the Earth's
atmosphere, biota and waters.Weathering
occurs in situ, or "with no movement", and
thus should not be confused with erosion,
which involves the movement of rocks and
minerals by agents such as water, ice, snow,
wind, waves and gravity.

23. Erosion
The removal of solids like sediments,
soil rocks and other particles in the
natural environment.

24. THE ERODED
MATERIALS GETS SET
DOWN INTHE EARTH
SURFACE.

25.  DUETOTHESE PROCESS DIFFERENT
LANDFORMSONTHE SURFACE OFTHE
EARTH .
LANDFORMS FORMED BYTHE RIVER

27. WATERFALL
 AWATERFALL IS A PLACE WHERE FLOWING
WATER RAPIDLY DRROPS IN ELEVATION AS IT
FLOWS OVER A STEEP REGION OR A CLIFF.
MEANDERS
A meander, in general, is a bend in
a sinuous watercourse or river.A meander is
formed when the moving water in a stream
erodes the outer banks and widens its valley
and the inner part of the river has less energy
and deposits what it is carrying.

28. OX BOW LAKE
An oxbow is a crescent-shaped lake
lying alongside a winding river.
The oxbow lake is created over
time as erosion and deposits of
soil change the river's course.

29. FLOODPLAIN
A floodplain or flood plain is an area of land
adjacent to a stream or river that stretches
from the banks of its channel to the base of
the enclosing valley walls and
experiences flooding during periods of high
discharge.

30. LEVEES
 Naturally formed raised bank along the side of a
river channel are called natural environment .
The river approaches the sea the river begins to
break up into many streams called distributaries

31. LANDFORMS FORMED BYTHE SEA
WAVES
Dueto continuous strikesof sea wavesat the
rocks,cracks appear in therocks.Changes
appear in the rocks.

33. LANDFORMS FORMED BY THE
GLACIERS

34.  THE DEPOSITSOF MATERIAL CARRIED BY
THE GLACIER IS CALLED GLACIAL
MORAINES.
