• lush green midland
• cool mountain slopes in the east

16. Identify the most widespread natural disaster in Kerala?
• Landslides

17. Which physiographic unit in Kerala experiences landslides the most?
• The highlands of Kerala

18. What is a landslide?
• During severe rains, a large quantity of water seeps into the soil.
• This exerts pressure on the pores in the soil.
• Due to the pressure of water, the soil under the loose rocks will move
downwards.
• Due to gravity, the whole or part of the area will collapse with a great
noise.
•  This phenomenon is known as a landslide.
• National Centre for Earth Science Studies has identified that places with
a slope above 20° are prone to landslides.

19. How are streams formed in the hilly terrains?
• After the landslide, the water stored in the soil starts flowing down as
streams.
• Many a time this flow will last only for a few days.
•  But on some occasions, there may become permanent streams

20. What are the unscientific activities along hilly terrains?
• Demolishing hillsides for soil.
• Cultivation of crops that need frequent tillage along steep slopes.
• Construction of houses and other buildings along steep slopes.

21.Why do we say that land utilization should be scientific in Kerala?
• Lack of space is one of the crucial problems that Kerala faces.
• More than 30% of the total land area of Kerala consists of slopes.
• Hence it is very essential that land utilization should be scientific.

22. Write scientific land-use practices
• Hillsides may be transformed into terraces in order to reduce the slop
•  The course of the natural streams in the hilly terrain should not be
blocked.
•  Construction activities along steep slopes should be avoided.

23. On what scale Earthquake disaster intensity in Kerala is measured?
• Moderate earthquake disaster

24. What are the precautions we should take for the Earthquake disaster?
• The construction of large buildings in seismically active zones should be avoided.
• Adopt seismic-resistant construction.
•  Light roofs are comparatively safe

25. What is a flood?
• When a large quantity of water flows into the rivers during the rainy
season, the river will not be able to hold the excess water and it overflows. This is known as a flood.

• Do not build houses on the river banks.
• Do not reclaim the paddy fields. They are the natural sinks for rainwater.
• Construct bunts on the river banks.
28. What do you mean by disaster mitigation measures.
• It is impossible to prevent natural disasters.
•  We can reduce their impact and bring the people back to normal life
through properly planned interventions. Such actions can generally be
called disaster mitigation measures.

explaining the steps to be adopted by the people in emergency situations.
• Organize orientation programmes on scientific land-use practices.

33. What steps we must adapt to ensure our safety in the event of natural
hazards in schools?
• For that the safe spots of the school have to be identified in advance.
•  Areas away from the buildings, preferably in the middle of the playground will be the safest.
• This is because of the fact that even if the building collapses the debris
might not fall here.
• Decide the path for ambulances and other rescue vehicles to the school campus.
• Do not make any modification in the campus obstructing this.
