According to the standard Big Bang model, the universe was born during a period of inflation that began about 13.8 billion years ago. Like a rapidly expanding balloon, it swelled from a size smaller than an electron to nearly its current size within a tiny fraction of a second. Our universe began with an explosion of space itself - the Big Bang. Starting from extremely high density and temperature, space expanded, the universe cooled, and the simplest elements formed. Gravity gradually drew matter together to form the first stars and the first galaxies. The best-supported theory of our universe's origin centers on an event known as the big bang. This theory was born of the observation that other galaxies are moving away from our own at great speed in all directions, as if they had all been propelled by an ancient explosive force.

A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 99 is about 9.950. Thus, the square root of 99 is not an integer, and therefore 99 is not a square number. 99 is a composite number because it has factors other than itself and one. For a number to be divisible by 99, the given number has to be divisible by 9 and 11. For a number to be divisible by 99, the given number has to be divisible by 9 and 11, both of which are simple tests. Divisible by 9 test. If sum of digits is divisible by 9 then the number is divisible by 9.

The hips, knees and ankles must all engage when we walk up stairs. As a result, your leg and hip muscles help move your joints through a variety of motions, including hip flexion, knee extension and flexion, ankle dorsiflexion and plantar flexion. Stair climbing works all of your major lower-body muscles, including glutes, hamstrings, quadriceps and calves. Strengthened gluteal muscles have the added benefit of making your butt look toned and firm. So – to reduce stress and pain in the knee, the best way to climb stairs is this – keep your body upright, try not to lean forward, place your entire foot on the next step, apply force through the heel, and focus on pulling your heel backwards behind your body as you straighten your leg to move your body up the stairs.

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.

Handpicking is a method to remove slightly larger impurities like pieces of dirt,stones and husk from wheat,rice and pulses by hand.

The distributive property is one of the most frequently used properties in math. In general, this term refers to the distributive property of multiplication which states that the. Definition: The distributive property lets you multiply a sum by multiplying each addend separately and then add the products. The distributive property of multiplication over addition can be used when you multiply a number by a sum. For example, suppose you want to multiply 3 by the sum of 10 + 2. 3(10 + 2) = ? According to this property, you can add the numbers and then multiply by 3.

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.
•     It shows their correct relation to one another as they are on the Earth.
•     A globe helps us to understand how day and night occur and how seasons are called.

A December 2017 report stated that 3.465-billion-year-old Australian Apex chert rocks once contained microorganisms, the earliest direct evidence of life on Earth. A 2013 publication announced the discovery of microbial mat fossils in 3.48 billion-year-old sandstone in Western Australia. Something profound happens when astronauts see Earth from space for the first time. Seeing planet Earth from space can cause a shift in awareness, according to NASA astronauts. This state of mental clarity is known as the "overview effect," in which the viewer becomes overwhelmed and awed by the size of Earth.

Ladakh is a cold desert in India. It lies in the Great Himalayas, on the eastern side of Jammu and Kashmir. It has the mighty Karakoram Range in the North and in the south, it is bound by the  Zanskar mountains. Several rivers flow through Ladakh. The most important one is the Indus.

These rivers form deep valleys and gorges. They add to the scenic beauty of the place. Several glaciers are found in Ladakh. The Gangotri glacier is an example. The altitude in Ladakh varies from about 3000m in Kargil to more than 8000 m in the Karakoram.

The desert type of climate is typical of Leh Ladakh with dry winds blowing throughout the day and summers being hot and humid. 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.
