A flood is a natural disaster where an area of dry land is suddenly submerged under water. It can be caused by heavy rain, dam breaking, overflowing rivers, or melting ice or snow. Prevention methods include retaining walls, town planning, vegetation, and education. An earthquake is a sudden shaking of the earth's crust due to the release of stress along geological faults or volcanic activity. A cyclone is an area of circular wind with low pressure at the center called the eye. Volcanoes form when hot magma escapes from below a planet's surface. Volcanic eruptions are studied in volcanology and measured using the volcanic explosivity index.

2.  A natural disaster is a major adverse event resulting
from natural processes of the Earth.
 Examples include floods, volcanic eruptions,
earthquakes, tsunamis, and other geologic processes.
 A natural disaster can cause loss of life or property
damage,

3. It is a natural event or occurrence where a
piece of land (or area) that is usually dry land,
suddenly gets submerged under water.

4. PREVENTION OF FLOODS
SEA/COASTAL
RETAINING WALLS
TOWN PLANNIG
VEGITATION
EDUCATION
CAUSES OF FLOODS
HEAVY RAIN
DAM BREAKING
OVERFLOWING OF RIVERS
ICE MELTING OR SNOW MELTING
STRONG WINDS IN COASTAL AREAS

5. A sudden movement of the earth's crust caused by t
he release of stress accumulated along geologic fau
lts or by volcanic activity.

7.  A cyclone is an area of closed, circular fluid motion.
It has low pressure on the inside and high pressure
on the outside.
 The center of the storm is called the eye and it has
the calmest water and the lowest pressure

8. WHAT CAUSE A CYCLONE

9.  A volcano is an opening in a planet’s surface which
allows hot magma to escape from below the surface.
 Study of volcano’s is called Volcanology and volcanic
eruptions are measured using Volcanic Explosivity Index.
