2. LAND FORMS – are natural
features that appear on the
surface of the earth
They are formed either by
the movement of the tectonic
plates or the action of water,
wind or ice.
3. THE TWO
REASONS OF LAND
FORMS
Destructive processes
Constructive processes
4. DESCTRUCTIVE
PROCESSES – Include
weathering, which is defined as
the physical and chemical
breakdown of Earth's material,
and erosion, which involves
transport of materials from one
place to another by water, wind
and ice.
5. CONSTRUCTIVE
PROCESSES – My include
plate tectonic processes
such as volcanic eruption ,
lava flows create a new
surface materials and rock
debris and volcanic ash are
deposited on earth’s surface.
20. LAVA – is hot molten rock or magma that
has erupted into earth crust.
TEPHRA – Refers to the airborne matter
from volcanic eruption
o BOMS – diameter greater than 64
mm
24. HILLS
is an elevated landforms and is
generally somewhat lower and less
steep than mountain.
It is also smaller than a mountain.
Hills also be volcanic. There are
squat volcanoes called CINDER
CONES
25. PLAINS
Plains are board, vast lands that roll slightly.
They are usually grassy areas with a few trees.
Plain, being flat and low-lying area, is a place
where deposition of sediments coming from
mountains occur.
26. VALLEYS
Is a low-lying area of land between two
mountains or hills.
27. WETLAND
The soil in wetland is usually low in oxygen
because the soil is slightly packed and soaked
with water.
Wetland plants adapt to life in wet soil.
