Life cycle of an insect: (Butterfly)

1. The young one of a butterfly that hatches out of the egg is called the caterpillar. 2. The caterpillar builds a cocoon around itself to form a pupa. 3. The pupa sheds its skin many times to change into an adult butterfly.

The process of shedding the old skin in insects several times before they grow into adults is called moulting.

Extra information:

Extra information:

Some mammals like spiny anteater and duckbilled platypus lay eggs.

Characteristics of mammals:

1. Mammals have most developed brain. 2. The body of most mammals is covered with hair. 3. Most mammals live on land and breathe through lungs. 4. They maintain constant body temperature, so called as warm-blooded animals. 5. All mammals look after their babies.

III. Answer the following questions: Q1) Define: a) Moulting - The process of shedding the old skin in insects several times before they grow into adults is called moulting. b) Mammals - Animals that give birth to their babies and suckle them are called mammals. Q2) Write five characteristics of a mammal. Ans) The five characteristics of mammals are – a) Mammals have most developed brain. b) The body of most mammals is covered with hair. c) Most mammals live on land and breathe through lungs. d) They maintain constant body temperature, so called as warm-blooded animals. e) All mammals look after their babies. Q3) Explain the lifecycle of a butterfly with the help of a well-labelled diagram. Answer. Like all insects butterfly also develop from eggs. The three stages in the life cycle of a butterfly are –

CLASS- IV E CONTENT FOR THE WEEK - 25.10.21 TO 29.10.21

TOPIC :- L-14 (OUR MINERAL RESOURCES)

SUB-TOPIC :- MINERALS, ORES, TYPES OF MINERALS( Metallic Minerals & Non-Metallic Minerals)

Content of the above lesson:-

• All rocks on the earth are made up of natural substances called Minerals .

• A rock that contains a large amount of a particular mineral is called the ore

of that mineral.

• Digging out of ores from underground is called mining.

• Deep holes are dug into the earth to take out ores. These holes are called

mines.

TYPES OF MINERALS:

• Minerals are broadly divided into two types:

A) Metallic Minerals

B) Non-metallic Minerals

METALLIC MINERALS:-

• Minerals from which we get metals are called metallic minerals.

Iron, copper, manganese, bauxite and gold are some metallic

minerals.

• The ores that we get from the mines are melted in big factories

to produce pure metals.

• Metals are minerals or substances that form naturally below

the surface of the Earth. Most metals are shiny.

• Alloy is a metal made by mixing two or more metals.

NON-METALLIC MINERALS

• Minerals from which we do not get metals are called non- metallic

minerals.

• Limestone, precious stones, salt, coal and petroleum are some

non- metallic minerals.

• Coal and petroleum are used as fuel. Therefore, they are

also called mineral fuels or fossil fuels.

• Fossil fuels are made from dead and decayed plants and animals.

These fuels are found in the Earth’s crust.

COAL:

Coal is used mainly as fuel. Some important coal mining centres are Jharia,

Dhanbad and Bokaro in Jharkhand; Raniganj in West Bengal and Korba in

Chhattisgarh.

PETROLEUM or MINERAL OIL:

• It is found deep inside the earth.

• Wells are drilled deep to reach the oil. An area with many oil

wells is called an oilfield.

• The mineral oil which is extracted is refined to make petrol,

diesel, kerosene and cooking gas.

• India has oil refineries in Digboi, Mathura, Haldia, Barauni

and Mumbai.

NATURAL GAS:

• It is found along with mineral oil in oilfields and used as a fuel

in the form of compressed natural gas (CNG) to run vehicles.

• The mineral reserves of the Earth are limited. Once they are used,

they are exhausted. They cannot last forever. So we must use the

available mineral reserves very carefully.

** Read the above content carefully and answer the following questions :-

I. Fill in the blanks :- (Write the complete sentence in your S.St copy)

1. All rocks on the earth are made up of natural substances

called .

2. Minerals are broadly divided into types.

3. ______ is a metal made by mixing two or more

metals.

4. The full form of CNG is ____________ natural

gas.

II. Questions and answers:- (Write the questions along with their answers

in your S.st notebook)

1. Define:

a) Ore b) Mining C) Fossil fuel

Ans. a) Ore: Ore is a natural rock or sediment that contains one or more

valuable minerals containing metals.

b) Mining: Digging out of ores from underground is called mining.

c) Fossil Fuels: Fossil fuels are made from dead and decayed plants and animals. These fuels are found in the Earth’s crust.

2.Differentiate between metallic minerals and the non-metallic minerals.

(Write any three points)

Ans. METALLIC MINERALS NON-METALLIC MINERALS

a) Minerals from which we get a) Minerals from which we do not

metals are called metallic minerals. get metals are called non-

metallic minerals.

b) Metallic minerals when melted, b) Non- metallic minerals do not

a new product is formed. produce any new product on

Melting.

c)Metallic minerals are hard. c)Non-metallic minerals are not

so hard.

3.What are mines?

Ans. Deep holes are dug into the earth to take out ores. These holes are called

mines.

4.Why should we use our mineral reserves carefully?

Ans. The mineral reserves of the Earth are limited. Once they are used, they

are exhausted. They cannot last forever.So we must use the available mineral

reserves very carefully.

5.Name the states along with places, which are famous for coal mining?

Ans . Some important coal mining centres are Jharia, Dhanbad and Bokaro in

Jharkhand; Raniganj in West Bengal and Korba in Chhattisgarh.
