Floods occur when bodies of water overflow their normal boundaries due to excessive water accumulation. Hailstorms form when rain drops become ice before hitting the ground, and heavy hailstorms can damage agriculture. Strong winds over bodies of water produce storms and dangerous waves. Tsunamis are caused by underwater earthquakes and have much longer wavelengths than ordinary waves, enabling them to destroy coastal areas. Acid rain forms from air pollution and causes acidification of land and water. Landslides are sudden movements of soil and rock masses often triggered by heavy rainfall or thawing that threaten natural and valley slopes. Fog reduces visibility dangerously by suspending water or ice crystals in the air. Ocean currents are directed sea water movements produced

2. Flood
A flood results
from an
overflow of
water beyond its
normal confines
of a body of
water such as a
lake, or the
accumulation of
water over land
areas.

3. Hail
Hailstorm is a type
of precipitation
where rain drops
become ice lumps
before they hit the
ground. Heavy
hailstorm with
particularly large
lumps of ice may
result in significant
losses, especially in
agriculture.

4. Storm
Phenomenon
occurring over
areas of the seas
and oceans in the
form of strong,
gusty wind.
Strong winds
give rise to a
huge and
dangerous
waves.

5. Tsunami
Tsunami can be
caused by
underwater
earthquakes.
Tsunami waves are
not like ordinary
ocean waves, since
their wavelength is
much longer.
A huge wave is more
dangerous because it
can strike at land and
destroy coastal

6. Acid rain
Acid rain is
precipitation
containing acids
produced in the
reaction of water
with engrossed
in air pollution
and cause
acidification.

7. Landslide
It is a sudden
movement of masses
of soil and rock
masses caused by
forces of nature. The
landslides may occur
as a result of increased
soil moisture due to
long-term rainfall or
thaw. Places where
landslides occur the
most often are natural
slopes and valley
slopes.

8. Fog
Fog - drops of
water (or ice
crystals) suspended
in the air.
Fog causes a
major reduction of
visibility which can
be very dangerous.

9. Ocean current
This is a
continuous,
directed movement
of seawater
generated by forces
acting upon this
mean flow, such as
breaking waves,
wind, the Coriolis
effect.
