In physics, gravity is the natural force that causes things to fall toward the earth. The noun gravity can also mean seriousness or solemnity. Someone who conducts themselves with an air of gravity is someone who takes what they are doing seriously. Gravity is a force which tries to pull two objects toward each other. Anything which has mass also has a gravitational pull. The more massive an object is, the stronger its gravitational pull is. Earth's gravity is what keeps you on the ground and what causes objects to fall.

The number of latitudes that cross this definition of India are 27 for the entire country or 25 for the mainland. No matter which definition you use of India's eastern and western boundaries, the whole number longitudes that cross India start with 68 and end with 97, so there are 30 longitudes that cross India.

Barter is a system of exchange where goods or services are directly exchanged for other goods or services without using a medium of exchange, such as money.

An example of barter is when the people within a community exchange goods and services so that money needn't be used.

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 Temperate Zones maintain a moderate climate, and the Frigid Zones are extremely cold. 

Solar system refers to the family of sun. The sun, the nine planets, the satellites and other celestial bodies such as asteroids and meteoroids forms the solar system

History can be generally defined as the past, and how past relates to the human lives. The main difference between history and prehistory is the existence of records; history is the recorded events of the past whereas Prehistory is the time before writing was introduced.

The Paleolithic was an age of purely hunting and gathering, but toward the Mesolithic period the development of agriculture contributed to the rise of permanent settlements. The later Neolithic period is distinguished by the domestication of plants and animals. Divided into three periods: Paleolithic (or Old Stone Age), Mesolithic (or Middle Stone Age), and Neolithic (or New Stone Age), this era is marked by the use of tools by our early human ancestors (who evolved around 300,000 B.C.) and the eventual transformation from a culture of hunting and gathering to farming and food production. During this era, early humans shared the planet with a number of now-extinct hominin relatives, including Neanderthals and Denisovans.

A globe is a perfect representation of the Earth because -

•     A globe represents the three-dimensional view if the Earth.
•     It shows the shape of the Oceans and the Continents correctly.

On your visit to Leh, you will face the colddesert climate, especially from October to March. In winters the temperatures are extreme in Leh, dipping below freezing point. Ladakh is called the Cold Desert. Desert lands with extremely low temperatures are called cold deserts like Antarctica, which is the largest cold desert in the world. Ladakh in India is a cold desert that lies in the Great Himalayas on the eastern side of Jammu and Kashmir.
