शरीर में जल का महत्त्वपूर्ण स्थान है। शरीर में जल की मात्रा लगभग 55-70 प्रतिशत होती है। जल का कार्य भोजन को घुलनशील नाना, शरीर के अनावश्यक पदार्थों को पसीने व मूत्र द्वारा बाहर निकालना है। जल विभिन्न पोषक तत्वों को शरीर के विभिन्न अंगों तक पहुँचाने का कार्य करता है। शरीर में उपस्थित जल त्वचा को नर्म, मुलायम एवं चमकदार बनाता है। इस प्रकार जल शरीर के लिए आवश्यक है।

सन्तुलित आहार वह आहार है जिसमें सभी पोषक तत्त्व जैसे प्रोटीन, कार्बोहाइड्रेट, वसा, विटामिन, खनिज लवण एवं जल आदि एक निश्चित मात्रा में पाए जाते हैं।

In desert regions, when the wind erodes the gentle and solid rocks into pointed land forms formed by sequential layers, such topography is known as Yardang.

In glacial regions, the egg – shaped topography which is formed during the process of deposition by the deposit of boulder bodies is known as Drumlin.

Stem or its vegetative part develops various modifications to carry out specialized functions. Such modified stems are called as metamorphosed stems.

Correct option: (a) Kaveri

The Scientific study of rocks is called‘Petrology’.

Granite, Gabbro, Diorite is the example for plutonic rock.

The rocks which are formed due to cooling of magma at great depth inside the earth are called Plutonic igneous rock’s.

C) Moulana Azad

These are formed due to the transformation of vegetative matter. Under the impact of heat and pressure the remains of plants are turned into hard layers. E.g. coal.

These are formed due to cementation and consolidation of pebbles and boulders e.g. Conglomerate and breccias. When large rounded pebbles are firmly cemented to form rocks they are known as conglomerate. When the rock fragments are angular and cemented together to form rocks. They are called breccias. These are porous rocks. 

Metallic Minerals are the minerals in metallic form or contain metal. Few metallic minerals are Iron ore, Manganese ore, Copper ore etc. Non-metallic minerals are not in metallic form and they do not contain metal. E.g. Mica, Sulphur, Lead, Zinc, Phosphate etc.

The rocks which are formed due to aggregation and compactness of sediments are known as “Sedimentary rocks.” These are formed by the deposition of sediments derived form older rocks, plants and animal remains by rivers, winds, glaciers etc. These sediments are hardened into rocks by pressure. Most often, they are formed on the bed of shallow seas or lakes and so they are called aqueous rocks.

The work of running water in the form of surface runoff or overland flow and streams is most important of all the exogenesis or plantation process e.g. ground water, sea waves, glaciers, wind etc. Because the running water is the most widespread exogenesis process on this plant earth.

The rocks having broad upper part and narrow base resembling an umbrella or mushroom are called Mushroom Rocks. These are formed due to abrasive work of wind. 

The rocks which are formed due to aggregation and compactness of sediments are known as “sedimentary rocks.” According to their origin and composition, sedimentary rocks can be divided into two main categories. They are:

1. Inorganic rocks: Inorganic rocks are rocks formed from mineral matter which has been obtained by disintegration or decomposition of rocks. Inorganic rocks can be divided into two types. They are

a. Mechanically-formed rocks: The rock which have been formed form the accumulation of rock materials, derived form other rocks and have been cemented together are known as “ Mechanically formed rocks.” The mechanically formed rocks consist of sediments which have been carried and deposited by rivers, glaciers, winds or waves and cemented – together with clay or line. On the basis of rock materials, these rocks can be divided into three main categories. They are:

1. Rudaceous rocks 

2. Arernaceous rocks 

3. Argilious rocks

i. Rudaceous rocks: Rudaceous rocks are formed due to cementation and consolidation of pebbles and boulders. Rudaceous rocks consist of rock pieces and grave, cemented together, by clay or line. They are porous and can hold water. If the rock pieces are angular in shape and cemented together, they are called breccias. If the rock pieces are rounded and cemented tighter, they are called conglomerate.

ii. Arenaceous rocks: These are formed mainly due to deposition, CQmmentating and consolidation of sane grains e.g. Sand stone.

iii. argillaceous rocks: These rocks are formed largely by fine clay particles e..g. Shale or mudstone these are impermeable.

B. Chemically formed rocks: The chemical often settle down and hardened to form rocks known as chemically formed rocks. For example: Gypsum and rock salt, running water dissolves and carries chemicals and where evaporation takes place, these chemicals are deposited at the mouth of springs, caves or caverns or in lakes. Rock salt and gypsum are formed form deposit of salt in strata on the beds of lakes.

C. Organic Rocks: Organic rocks are formed form the remains of organisms, i.e. of animals and plants. Examples: coal, limestone etc. On the basis of lime and carbon content, organically formed rocks can be divided into two kinds, namely. 

a. Calcareous rocks: Calcareous rocks are formed mostly from the remains of living organisms. These rocks contain calcium carbonate or lime. They include limestone and chalk. They are porous and soluble.

b. Carbonaceous rocks: These are formed due to the transformation of Vegetative . matter. Under the impact of heat and pressure the remains of plants are turned into hard layers. E.g. coal.

Based on Origin and composition sedimentary rocks are divided into three types 

1. mechanically formed rocks. 

2. Chemically formed rocks. 

3. Organically formed rocks.
