Question

what are landslides and give any two protective measures

Answer 1

Landslides:

Landslides refer to a rapid down-slope
movement of rocks or soil mass under
the force of gravity. It is also known as
slope failure and mass wasting.
Landslides may be typed as mudflow
where there is down-slope movement of
soil and debris flow, which is the down-
slope movement of coarse material and
rocks. Landslides may occur when water
from rain and melting snow, seeps
through the earth on a sloppy surface
and encounters a layer of loose, unstable
material such as clay.
Landslides mostly occur on unstable
hillsides by the action of rain or snow
that seep through the soils and rocks . This results in the slopes. All the hilly regions of our
country are prone to landslides.
sliding of earth and rock masses down
the hill slopes. These are further
triggered due to deforestation and
human encroachment on unstable

Prevention, Control and Mitigation:

Though landslides are a natural
phenomenon and may occur without
human interference, in certain cases
human activities like deforestation,
mining, etc. can also induce landslides.
Landslides can be controlled, to some
extent, by adopting initiatives, such as
providing slope support and minimizing
human encroachment.
