This is most important series of geography class 10 ICSE. We will provide all detail solution step by step.
MOST IMPORTANT QUESTIONS OF GEOGRAPHY ICSE CLASS 10 , PART 03
1.
REASON: TERRANCE FARMING IS AN IDEAL FOR
SOIL CONSERVATION FOR HILLY REGIONS
ü Steps are built
on the slopes of the mountains to create flat lands to grow crops .Terrance
farming is useful as it shows down the speed of water running down the mountain
and preserves soil from erosion.
2.
DRY FARMING IS PREFERRED IN AREA WITH RED
SOIL
ü Because red soil
is formed due to poor rainfall.
3.
WIND IS COMMON AGENT FOR SOIL EROSION IN
ARIED REGION
ü Arid regions are
devoid of any moisture and have scanty vegetation cover, hence wind blows off
soil is common agent of soil erosion.
4.
BRIEFLY : MENTION ONE WAY IN WHICH MAN IS
RESPONSIBLE FOR SOIL EROSION
ü cutting down the
tree in forests i.e. deforestation led soil erosion
5.
HOW CAN DEEPENING OF RIVERBEDHELP IN
PREVENTING SOIL?
ü Deepening of the
river bed decreases the flow the river which helps in preventing soil erosion.
6.
MENTION PHYSICAL CHARACTER OF LATERITE SOIL.
ü Laterite soil is
formed by leaching. It is found in Andra Pradesh, Tamil nadu, west Bengal, Odisha,
Karnataka, etc.
ü the
characteristics of laterite soil are 1.red in color with high content of iron
oxides
2. Poor in nitrogen and lime
3. Rich in iron
4. Course in texture.
5. Soft and friable.
6. High content of acidity and inability to retain
moisture
7.
WHY DOES ALLUVIAL SOIL DIFFER IN TEXTURE?
ü Alluvial soil
differs in texture because it is formed due to erosional, depositional and transportation
activities by river. So the upper coarse in the river is coarse and in the
lower coarse is fine.
8.
STATE TWO CROPS THAT WELL GROW IN ALLUVIAL SOIL
=
ü Cereals and
cotton
9.
NAME ONE IMPORTANT CROP THAT GROWN IN BLACK
SOIL=
ü Jower and wheat
10.
GIVE CHEMICAL PROPERTY OF BLACK SOIL
ü Rich in iron,
potash, lime, calcium, alumina, magnesium and carbonates.
11.
WHY RED SOIL REQUIRES IRRIGATION.
ü It is loamy and
cannot retain water.
