Alluvial soil-Alluvial soil occurs throughout the Indo-Gangetic Plain and along the lower courses of virtually all the country’s major rivers (especially the deltas along the east coast).
Black soil-Black soil is found mostly across Gujarat, Maharashtra, Karnataka and Madhya Pradesh on the Deccan lava plateau and Malwa plateau.

The service sector in India employs the following two different kinds of people. They are:

• The people involved in the services that may directly help in the production of goods. For example, people involved in the transportation, storage, communication, finance etc.
• The people involved in such services that may not directly help in the production of goods e.g. teachers, doctors, barbers, cobblers lawyers etc. They may be termed as ancillary workers means those who give services to the primary service providers.

The First World War wreaked large scale havoc around the world in many senses. About 9 million people died and 20 million people were injured in the wake of the war.

Most of the people who were killed or maimed were people from working age. This resulted in a significant reduction in the number of able-bodied workforce in Europe. Due to fewer earning members in the families, the household incomes drastically reduced in Europe.

Most of the men were forced to engage in war and thus women had to replace them in factory jobs. Women were now working in those jobs which were earlier considered as male bastions.

ONLY two animals can see behind themselves without turning their head and they are rabbits and parrots. Their eyes are on the sides of their head, instead on the front and this allows them to swivel 360 degrees.

The land which is unsuitable for cultivation due to soil erosion is called ravines. Ravines are large ditches caused by water erosion. Typically, in the Southwest, when rain falls in the mountains, the water comes streaming down, and when multiple water streams combine, their effects are multiplied, and severe erosion occurs.

Badlands are a type of dry terrain where softer sedimentary rocks and clay-rich soils have been extensively eroded by wind and water.[1] They are characterized by steep slopes, minimal vegetation, lack of a substantial regolith, and high drainage density.[2] They can resemble malpaís, a terrain of volcanic rock. Canyons, ravines, gullies, buttes, mesas, hoodoos and other such geologic forms are common in badlands. They are often difficult to navigate by foot. Badlands often have a spectacular color display that alternates from dark black/blue coal stria to bright clays to red scoria

Major Iron Ore Belts in India

1. Orissa Jharkhand Belt: Badampahar mines in the Mayurbhanj and Kendujhar districts of Orissa have high grade hematite ore. Additionally, hematite iron ore is mined in Gua and Noamundi in Singhbhum district of Jharkhand.
2. Durg Bastar Chandrapur Belt: This belt lies in Chhattisgarh and Maharashtra. The Bailadila range of hills in the Bastar district of Chhattisgarh have very high grade hematite ore. This hilly range has 14 deposits of super high grade hematite ore. Iron from these mines is exported to Japan and South Korea via Vishakapatnam port.
3. Bellary Chitradurga Chikmaglur Tumkur Belt: This belt lies in Karnataka. The Kudremukh mines located in the Western Ghats are a 100 percent export unit. The ore from these mines is transported as slurry through a pipeline to a port near Mangalore.
4. Maharashtra Goa Belt: This belt inculdes the state of Goa and Ratnagiri district of Maharashtra. The ores in these mines are not of very high quality. They are exported through Marmagao port.

There are many differences in Indian farming and US farming methods.

1. India is basically an agriculture-based country with 80% of its population in rural areas, whereas in the US, only a small number of people are involved in farming.

2. The average farm holdings in the India are of small sizes (2-3 hectares), whereas in the US, the farm holdings are large (250 hectares).

3. Most of the Indian farmers are uneducated or receive basic education in the village schools, whereas in the US, the farmers are mostly well educated and keep themselves updated with the latest developments in the agriculture field.

4. Indian farming is labor intensive and traditional methods of farming like plowing is used, whereas, in the US, heavy and advanced machinery is used for farming which is capital intensive.

5. Indian farming is weather dependent and farmers grow only 2-3 crops per year. In the US, the farmers use scientific techniques like soil testing etc. and grow multiple crops throughout the year.

6. The US farmlands give bigger returns to the farmer when compared to the Indian farmlands.

Metallic Minerals are minerals in which metal elements are present in their raw form. Non-metallic minerals do not contain any metal substances in them. When metallic minerals are melted a new product is formed. Metallic minerals are minerals which contain one or more metallic elements. Metallic minerals occur in rare, naturally formed concentrations known as mineral deposits. Metals such as nickel, copper and zinc are fundamentally important to modern society since they are used for an endless variety of purposes. Non-Metallic Minerals: As the name suggests, non-metallic minerals are the minerals that do not contain metals, e.g. limestone, mica, coal, gypsum, dolomite, phosphate, salt, manganese, granite etc. They are the minerals that do not contain metallic elements. They are generally hard and have a shiny surface.

Improving the Centre-State relations is one more way in which federalism has been strengthened in practice. Though Indian Constitution has demarcated the powers of the Union and the state governments but still the Union government can have influence over the state in many ways.
In the past, the Central government has often misused the Constitution to dismiss the state governments that were controlled by rival parties. This undermined the spirit of federalism, and that of democracy.
The judiciary has played a major role in improving the autonomy of the state governments because many a time, it has rescued state governments which were dismissed in an arbitrary manner.

In Belgium, leaders recognised the existence of regional differences and cultural diversities. The Belgian government accommodated its diverse ethnic population in the following manner:

• Constitution says that the number of Dutch and French speaking ministers shall be equal in the Central government. Thus, no single community can make decisions unilaterally.
• Many powers of the Central Government have been given to the state governments, of the two regions of the country. The state governments are not subordinate to the Central government.
• Brussels has a separate government in which both the communities have equal representation.
• There is a third kind of government, called the ‘community government’. This government is elected by the people belonging to one language community—Dutch, French and German speaking, no matter where they live. This government has the power regarding cultural education and language related issues.
  These arrangements helped to avoid a civic strife between the two major communities and a possible division of the country on linguistic lines.

Federalism has two levels of government:

• One is the government for the entire country that is usually responsible for a few subjects of common national interest.
• The others are governments at the level of provinces or states that look after much of the day-to-day administering of their state.

The system of checks and balances ensures that no one branch of the national government gains too much power. A system of checks and balance prevents any one branch of government from having a lot of power. All three branches of the government are kept in balance with a checks and balance system in place.
So that no governmental branch can have more power than the other.
