The spinning of the Earth on its axis from west to east is called rotation.

Effects of the Earth’s rotation are:

• The rotation of the Earth causes the day and the night. The part of the Earth facing the Sun experiences day while the part which does not face the Sun experiences night.
• The speed of the Earth’s rotation has affected the shape of the Earth. Because of the speed of rotation, a centrifugal force is created which leads to the flattening of the Earth at poles and bulging at the center.
• The Earth’s rotation affects the movement of water in the oceans. The tides are deflected due to the rotation.
• The speed of rotation also affects the movement of the wind. Due to rotation, winds and the ocean currents deflect to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

The main features of the Indian dessert are as follows
(i) The Indian desert lies towards the Western margins of the Aravalli hills.
(ii) It is an undulating sandy plain covered with sand dunes.
(iii) This region receives very low rainfall, below 150 mm per year. It has an arid climate with low vegetation cover.
(iv) Streams appear during the rainy season. Soon after, they disappear into the sand as they do not have enough water.
(v) Luni is the only large river in this region. Barchans (crescent shaped dunes) cover larger areas, but longitudinal dunes become more prominent near the Indo-Pakistan border.

  A disaster is a sudden, calamitous event that seriously disrupts the functioning of a community or society and causes human, material, and economic or environmental losses that exceed the community's or society's ability to cope using its own resources.

Mahatma Gandhi led the national freedom struggle against the British rule. The most unique thing about this struggle was that it was completely nonviolent. Mohan Das Karamchand Gandhi was born on 2nd October, 1869 at Porbandar in Gujarat.

The ozone layer is a deep layer in the stratosphere, encircling the Earth, that has large amounts of ozone in it. ... Interestingly, it is also this ultraviolet radiation that forms the ozone in the first place. Ozone is a special form of oxygen, made up of three oxygen atoms rather than the usual two oxygen atoms. The ozone layer, also called the stratosphere, is composed of the ozone gas (90% of the total ozone in the atmosphere). The ozone has three oxygen atoms, and it is the result of the action of Ultra Violet (UV) radiation on oxygen molecules, composed of two oxygen atoms.

Heat zones are the different zones of the earth, where the sun's rays fall differently, thus causing different climate patterns. These zones are called the Torrid Zone, the two Temperate Zones, and the two Frigid Zones. The Torrid Zone is very hot since the sun shines overhead here. The earth has three main heat zones – torrid zone, temperate zone and frigid zone.

1. A globe is a simple and accurate model of the earth.
2. It shows the distribution of land and water on the surface of the earth.
3. It shows the correct shape, size and location of the continents and oceans on globe.

1. A globe is a simple and accurate model of the earth.
2. It shows the distribution of land and water on the surface of the earth.
3. It shows the correct shape, size and location of the continents and oceans on globe.
So we can say that globe is too helpful for us.

(i) Organs of the government: Legislature, executive and judiciary are the three organs of the government. Legislature is responsible for making laws, executive organ is responsible for execution or implementation the laws whereas judiciary is there to provide justice to the people or to solve the disputes.
(ii) Power sharing: In India the Union Parliament, i.e., the Lok Sabha and the Rajya Sabha makes laws whereas various ministers and government officials are responsible for the execution of the laws. These ministers are not independent but they are responsible or answerable to the Parliament or State Assemblies. Similarly, although judges are appointed by the executive, they can check the functioning of executive or laws made by the legislatures. This arrangement is called a system of checks and balances.

A body of water or waterbody (often spelled water body) is any significant accumulation of water, generally on a planet's surface. ... Some bodies of water collect and move water, such as rivers and streams, and others primarily hold water, such as lakes and oceans. The Seven Seas include the Arctic, North Atlantic, South Atlantic, North Pacific, South Pacific, Indian, and Southern Oceans. The exact origin of the phrase 'Seven Seas' is uncertain, although there are references in ancient literature that date back thousands of years.

From largest to smallest, the five oceans are Pacific, Atlantic, Indian, Southern, and Arctic. Together, they cover almost 71% of the earth's surface.

1. The availability of these resources is limited under both quality and quantity: In simpler words, limitation is one of the characteristics. Some of the resources are abundantly available and some are scarcely available.

2. Usefulness: All of the resources are very useful and specific in their own way.

3. Resources are ‘interdependent’ and inter-related to each other: These resources are used at a time.

4. Resources has multiple uses. 

The Himalayas form a huge mountain range made up of minor ranges and surround the western and southern edges of the Tibetan Plateau. Stretching from mainland China in the east to Pakistan in the west, across Bhutan, Tibet, Nepal and northeast India, the range is the largest in the world, and exists wholly in Asia. The Himalayas form a 1500-mile arc through northeastern Pakistan, northern India, southern Tibet, Nepal, Sikkim, and Bhutan. To the north is the high plateau of central Asia and to the south are the plains of central India. The Himalaya Mountain Range has nine of Earth's fourteen peaks over 8,000 meters high. The Himalayas are inhabited by 52.7 million people, and are spread across five countries: Bhutan, China, India, Nepal and Pakistan.

There are four main types of disease: infectious diseases, deficiency diseases, hereditary diseases (including both genetic diseases and non-genetic hereditary diseases), and physiological diseases. Infectious diseases are disorders caused by organisms — such as bacteria, viruses, fungi or parasites. Many organisms live in and on our bodies. They're normally harmless or even helpful. But under certain conditions, some organisms may cause disease. Some infectious diseases can be passed from person to person.

We need food for the following reasons:

1. For our survival
2. Food gives us energy
3. Foods help us to grow
4. It repairs the damaged cells of the body
