Explain thee three types of soil erosion mostly observed in India. Explain three human activities responsible for soil erosion. CBSE Class X Social Science LA (5 Marks)

Answer»

Types of Soil Erosion 
There are three MAIN types of soil erosion.

WIND erosion: Wind erosion is the removal soil PARTICLES by the force and kinetic energy of the wind. These soil particles are transported and deposited when the wind energy drops.

Water erosion: Water erosion is caused by the kinetic energy of rain FALLING on the soil surface and by the mechanical force of runoff.

Gravity erosion: Mass movement of soil occurs on STEEP slopes under the influence of gravity. The process involves the transfer of slope-forming materials from higher to lower grounds due to self weight.

The canal is used by European maritime trade companies to exchange goods with India, China and South East Asia. Before its construction, the only way to make this journey was going around South Africa through the CAPE of Good Hope route.As the info-graphic explains, the canal SHORTENED this path by 8200 kilometers. This was a huge cut off at the time since sea trade was very costly then. Of course, this made maritime trade grow even more allowing GLOBAL trade to be more powerful than ever.

Mathematics question1500 soldiers in a fort have provision for 48 days.After 13 days few soldiers join them and then the food lasts for 25 days.How many soldiers join ?Solve by ratio and proportion method. Plzzzzzzz.... fast.........

Answer»

1500 soldiers………………………………………Breads 48 days.

After 13 day …………………………………………..Breads 35

days……………………Total soldiers 1500+x .

For 1500 +x…………………………………………….Breads LAST 25 days .

if 1 soldier EAT 1 Bread in 1 day 1500 eat 1500 rotis in 1 day and for 48 days 1500 × 48 = 72000 Breads provided till 13 days there are only 1500 soldiers that means 1500 × 13 = 19500.

Bread remains after 13 days is 52500 That means the remaining Bread is for (1500 + x) soldiers .

According to the problem,52500/1500 + x = 25.52500 = 37500 + 25x.25x = 15000.x = 600600 Soldiers JOINED.

LATITUDE is an angle (defined below) which ranges from 0° at the Equator to 90° (North or South) at the poles. Lines of constant latitude, or parallels, run east–west as circles parallel to the equator.

Longitude is a geographic coordinate that specifies the east-west position of a point on the Earth's surface. It is an ANGULAR measurement, usually EXPRESSED in degrees and denoted by the GREEK letter lambda (λ). Meridians (lines running from the North POLE to the South Pole) connect points with the same longitude.

Explain any five reasons responsible for water in a india

Answer»

Five reasons for water SCARCITY in India are :

(i) SEASONAL and annual variation in precipitation.

(ii) Unequal access.

(iii) Overexploitation.

(iv) Availability of water varies over space and time.

(v) Excessive use of water resources.

(vi) Many cities have large and growing population resulting in greater demand for water resources. A large population means, not only more water is required for domestic use but also for higher foodgrain productivity. This has led to over-exploitation of water resources to expand irrigated areas ESPECIALLY for dry season agriculture. It has also contributed to falling ground water levels, adversely affecting the water availability and food security of the people.

(vii) Today the multinational COMPANIES and other industrial units consume large quantities of hydroelectric power and for processing which put greater pressure on the existing fresh water resources in India. Multiplying urban areas with dense population and modern life styles have created an ever increasing demand for water and energy resources.

(viii) Pollution of water bodies DUE to discharge of industrial effluents, use of pesticides, insecticides and fertilisers used in agriculture, make the river water hazardous for human consumption.

5175.

How are resources important

Answer»

Necessity of resources for human beings:

(i) Satisfaction of needs:

Human beings use resources as raw material to satisfy their needs and comforts. They use them for making clothes, food, construct houses, set up industries etc. They use energy resources like coal, gases, petroleum, wood etc. for GENERATING POWER, electricity or as a fuel to run vehicles, factories etc.

(ii) Economic development:

These natural resources are of great economic IMPORTANCE. They are the main source of our agricultural activities. They provide raw materials for the industry. All commercial activities directly or indirectly DEPEND upon them.

(iii) Employment opportunity:

Natural resources provide jobs and employment to millions of people. In our country more than seventy percent people are engaged in farming.

(iv) Products:

Many valuable products are obtained from these resources. Agriculture is BASED on proper utilization of land and water resources. Industries use forests, wildlife, water, mineral, and agriculture and power resources. The development of industries of a country depends upon the availability of resources.

The poem of Aajiche Ghadyal

Answer»

आजीच्या जवळी घड्याळ कसले आहे चमत्कारिक,
देई ठेवुनि तें कुठे अजुनि हे नाही कुणा ठाउक;
त्याची टिक टिक चालते न कधिही, आहे मुके वाटते,
किल्ली देई न त्यास ती कधि, तरी ते सारखे चालते

“अभ्यासास उठीव आज मजला आजी पहाटे तरी,”
जेव्हा मी तिज सांगुनी निजतसे रात्री बिछान्यावरी
साडेपाचही वाजतात न कुठे तो हाक ये नेमकी
“बाळा झांजर जाहले, अरवला तो कोंबडा, उठ की !”

ताईची करण्यास जम्मत, तसे बाबूसवे भांडता
जाई संपुनियां सकाळ न मुळी पत्त कधी लागता !
“आली ओटिवरी उन्हे बघ!” म्हणे आजी, “दहा वाजले !
जा जा लौकर !” कानि तो घणघणा घंटाध्वनी आदळे.

Distinguish between endogenetic and exogenetic forces.

Answer»

ENDOGENETIC FORCES

They originate in the INTERIOR of EARTH.
Cause sudden (through earthquake and volcanoes) or slow movements.
The energy for these forces is generated by radioactivity, rotational and tidal friction and primordial heat.
Endogenic forces can further be divided into two parts:-
Diastrophism:- It includes slow bending, folding, warping and faulting of earth crust. Orogenic movements (mountain building forces) and Epeirogenic movements (continents building forces) are two MAIN forms of diastrophism. These forces work very slow and their work is almost imperceptible.
Sudden Movements:- These movements cause considerable deformation of earth’s crust over a very short span of time. These are of two types- Earthquake and Volcanoes.
Examples- Mountain building such as Himalayas, Rockies and Andes; African Rift Valley DUE to Faulting.
EXOGENIC FORCE

They occur on the earth’s surface.
They work to wear down the reliefs and elevations (degrade) and fill up (agrade) the depressions on the earth surface.
All the exogenic processes can generally be called as Denudation which means strip off or uncover.
Denudation includes weathering, mass wasting, erosion and transportation.
These forces are a direct result of stress induced in earth materials due to various forces which occur due to sun’s heat.
Main forces involved are:-Gravitational forces, molecular stress, chemical actions, and kinetic energy.
Effects of most of the exogenic forces are slow but in a long run they affect the rocks drastically through wearing the rocks down and accumulating the weathered or eroded material to create new landforms.
Examples- Formation of river valleys, springs, deltas, sand dunes, beaches ETC.
