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 06
1.
WHY IS THIS SOIL AGRICULTURALLY IMPORTANT?
ü Black soil is
formed due to disintegration of basalt which is suitable for cotton.
2.
GIVE REASON: RED SOIL IS RED IN COLOUR.
ü rich in iron
oxide
3.
GIVE REASON: LARGE TRACTS IN MAHARASTRA IS COVERED WITH BLACK
SOIL.
ü Because of in
situ soil which is formed at its own position.
4.
GIVE REASON: MAN IS LARGELY RESPONSIBLE FOR
SOIL EROSION.
ü Because of the
man made activities such as deforestation, jhooming , grazing land etc.
5.
NAME THE SOIL WHICH IS FORMED DUE TO HIGH
TEMPERATURE AND HEAVY RAINFALL WITH ALTERNATING WET AND DRY PERIOD= laterite soil
6.
NAME THE STATE STATES WHERE THIS TYPE OF SOIL
IS FOUND? = Andra Pradesh , Tamil nadu , west Bengal , Kerala
7.
WRITE THE CHRACTERISTICS OF RED SOIL?
Red soil formed
in situ by weathering of crystalline and metamorphic rocks and has a mixture of
clay and sand. It is found large part of Tamil nadu, Karnataka, north – east
Andra Pradesh, Chhattisgarh, and Odisha
The
characteristics of red soil are as follows:
1. Red in color
2. Present in
high iron oxide content,
3. Deficient in nitrogen, lime, phosphorous, and humus.
4. Rich in
potash.
5. Porous, friable, but not retentive of moisture.
ü
8.
WHAT IS CONSERVATION OF SOIL?
ü Soil conservation
refers to the steps taken to protect the soil from erosion.
9.
NAME ANY TWO FARMING TECHNIQUES WHICH HELP IN
SOIL CONSERVATION?
·
Strip cropping
·
agro forestry
10.
DEFINATION:
TRANSPOTATION SOIL: - This soil is formed when the agents of erosion deposit
sediments at the place,
IN SITU: - soil is formed at their originate
position by weathering of parent rocks is called in situ,
11. NAME THE SOIL IN WHICH COVERS THE SUMMITS OF EASTERN
GHATS.= alluvial soil
12. NAME THE SOIL IN WHICH MAKES UP THE DELTA OF THE RIVER
GANGA.= alluvial soil
13. NAME THE SOIL IN WHICH IS THE MOST SUITABLE FOR THE
CULTIVATION OF COTTON?= black or regur soil
14. NAME THE SOIL WHICH IS STICKY WHEN WET AND CRACKS WHEN
DRY?=black soil or regur soil
15.
WHAT IS SOIL
CONSERVATION?
ü Soil conservation
refers to the steps taken to protect the soil from erosion.
16. HOW DOES REFFORESTATION HELP IN SOIL CONSERVATION?
ü Reforestation is
the planting of trees .the roots of trees can hold the soil and prevents from
soil erosion.
17. NAME THE PROCESS BY WHICH LATERITE SOIL IS FORMED? =
leaching
18. WHAT CLIMATIC CONDITIONS ARE RESPONSILE FOR ITS FORMATION?
high temperature and heavy rainfall
19. GIVE REASONS FOR:
BLACK IS LARGELY FOUND IN
THE DECCAN TRAP REGION.
ü
20.
GIVE REASONS FOR: KHADAR IS MORE FERTILE THAN BHANGAR.
ü khader is new
alluvial soil where as bhanger is old alluvial soil
21.
SOIL EROSION BY WIND IS COMMON IN ARID
REGIONS.
ü
22.
NAME TWO STATES IN INDIA WHERE REGUR SOIL
IS FOUND? = Gujarat and Maharashtra
23.
IN WHAT WAY
DOES REGUR SOIL IS FOUND?
ü Regur is volcanic
origin – lava formed due to disintegration of basalt.
24.
STATE THE DIFFERENCE BETWEEN ALLUVIAL SOILS FOUND IN
LOWER COURSES AND THE UPPER COURSES.
25. NAME THE TWO IMPORTANT AGAINTS OF EROSION?= wind and
running water
26. STATE ONE METHOD OF CONTROLLING THE EROSION CAUSED? strip
cropping
27. STATE TWO METHODS OF CONTROLLING THE EROSION OF SOIL
CAUSED BY RUNNING WATER?
ü Sheet erosion: the steep slope has more erosive power
of the rain causing sheet erosion over vast stretches.
ü Gully erosion: gully erosion takes place when water
runs down or gushes in distinct path, forming hills which deepen to form
ravines or gullies
29.
WHICH MAKES THE BLACK SOIL FERTILE?
ü insitu type of soil rich in iron potash lime calcium
,alumina magnesium and carbonates
30.
GIVE REASONS FOR: LATERITE IS UNSUITABLE
FOR CULTIVATION.
ü LATERITE SOIL IF
FORMED BY LEACHING OF LATERITIC SOIL UNDER HIGH TEMPERATURE AND HEAVY RAINFALL
WITH ALLTERNATING DRY AND WET PERIODS .LEACHING LIME AND SILICA LEAVES BEHIND A
POOR SOIL WHICH IS UNSUITABLE FOR GROWTH.
