Question 3
1 / -0

The best quality iron ore is ____________

A
Hematite

B
Magnetite

C
Siderite

D
Limonite

Solution

There are four major types of iron ore.
1- Magnetite (Fe$$_3$$O$$_4$$) is the richest of the common iron minerals. It contains 72.4% iron. The is darker than that of hematite, varying from deep dark brown to blackish.
2- Hematite (Fe$$_2$$O$$_3$$), it contains nearly 70% iron. It mostly reddish. Some hematite is almost black or even blue.
3- Limonite (2Fe$$_2$$O$$_3$$.3H$$_2$$O) or brown ore. It contains 60% iron content. Its colour ranges from yellow to dark.
4-Siderite (Fe$$_2$$CO$$_3$$), it contains about 48% iron content.
Question 4
1 / -0

Which one of the following type of resource is iron ore?

A
Renewable

B
Biotic

C
Flow

D
Non-renewable

Solution

Iron ore is a non-renewable mineral resource. Once it is consumed it cannot be generated again.
Question 5
1 / -0

The store-house of minerals in India is __________.

A
Northern plains

B
Deccan plateau

C
Himalayan mountains

D
Thar desert.

Solution

From the given options, Deccan plateau is called the store house of minerals in India.
Question 6
1 / -0

Iron ore is ______.

A
Abiotic resources

B
Renewable resource

C
Both (1) and (2)

D
None of these

Solution

Abiotic resources comprise of non-living things like land, water, air and minerals such as gold, iron, copper and silver. Abiotic resources are not renewable, as they can be exhausted by excessive use and their rate of formation is very slow. The usefulness of the abiotic resources depends upon their accessibility and their value.
Question 7

Which one of the following is a non-metallic mineral?

A
Copper

B
Lead

C
Limestone

D
Tin

Solution

Limestone is a sedimentary rock (an organic sedimentary rock ). It is composed of calcium carbonate and magnesium or mixture of these two constitutes. From the given options, limestone is a non-metallic mineral.
Question 8
1 / -0

Iron ore is an example of ________.

A
Renewable

B
Flow

C
Biotic

D
Non-renewable

Solution

Iron ore is an example of non-renewable resource. Non-renewable resources are environmental resources that cannot be replenished. Once they have been used up, there will be no more. Most non-renewable resources are minerals, which are mined, for example, gold, iron ore, titanium. Coal and oil are known as fossil fuels and are also non-renewable.
Question 9
1 / -0

Which one of the following minerals is an example of energy mineral?

A
Iron

B
Coal

C
Mica

D
Zinc

Solution

It is used as a domestic fuel, in industries such as iron and steel, steam engines and to generate electricity. Electricity from coal is called thermal power.
Question 10
1 / -0

The difference between tidal energy and wave energy is that

A
Wave energy uses the gravitational pull of the Earth and moon to generate energy

B
Tidal energy uses kinetic force of waves to produce energy

C
Tidal energy uses the gravitational pull of the Earth, moon and sun to generate energy

D
None of these

Solution

Tidal energy uses gravitational pull of Earth, moon and sun to produce energy where as a wave energy uses kinetic forces of waves to generate electricity. The tides at shorelines of oceans will rise and fall about twice a day.
