You've reached the end
number 2 must be illegal
India was never for beginners 😂
What did he do by compressing the forks?
What is the name of the song from number 3?
What if the phone dies while a cop is behind on the second
Number three is actually useful if you’re living wheelies if you’re about to loop it pulls the rear brake
What did he do by compressing the forks? спасибо
Man, it's not india
a dont have rear brake in my moto
Yoo man sorry for not commenting now i will come back
Wait I’m confused does the wheelie thing prevent you from looping?
People hide their tags because they don’t have the ⚽️⚽️ to speed with the risk or being caught.

Those who don't know I am too indian and I too modify suzuki by fan to back light which look cool 😂😂😂😂😂
Gda mark yessssss
Bro I am from India 😂
Good
hi
That’s not India
Air is the invisible, life-sustaining mixture of gases that surrounds Earth and makes up our planet's atmosphere. It's essential for almost all life on Earth, drives weather, enables flight, and even influences sound and combustion. Here's a bunch of interesting stuff about it: Basic Composition Dry air near sea level is roughly: Nitrogen (N₂): ~78% — inert, doesn't react much. Oxygen (O₂): ~21% — the stuff we breathe to produce energy. Argon (Ar): ~0.93% — a noble gas. Carbon dioxide (CO₂): ~0.04% (around 420 ppm today) — critical for plants and the greenhouse effect. Trace gases: Neon, helium, methane, krypton, hydrogen, ozone, and others. There's also water vapor, which varies from nearly 0% in deserts to 4% in humid tropics. Water vapor is the most important greenhouse gas by far. Physical Properties Mass and pressure: Air has mass (about 1.2 kg per cubic meter at sea level). Atmospheric pressure at sea level is ~101.3 kPa (14.7 psi), created by the weight of the air above you. This pressure decreases with altitude. Compressibility: Unlike liquids, air compresses easily, which is why airplane cabins need pressurization and why we can pump air into tires. Temperature: It gets colder as you go up in the troposphere (about -6.5°C per km), then behaves differently in higher layers. Speed of sound: Sound travels through air at about 343 m/s (1,235 km/h or 767 mph) at 20°C. It varies with temperature, density, and humidity. Layers of the Atmosphere From the surface up: Troposphere (0–12 km): Where we live and where weather happens. Stratosphere (12–50 km): Contains the ozone layer that blocks UV radiation. Mesosphere: Meteors burn up here. Thermosphere: Very thin, high temperatures, auroras occur. Exosphere: Transitions into space. Why Air Matters Breathing: Humans need oxygen; we inhale ~11,000 liters of air per day. At high altitudes (above ~2,500–3,000m), lower oxygen pressure can cause altitude sickness. Photosynthesis and the carbon cycle: Plants use CO₂ + sunlight + water to make food and release oxygen. Weather and climate: Air movement (winds), moisture, and temperature differences drive everything from breezes to hurricanes. The atmosphere acts like a giant heat engine. Protection: It burns up most meteoroids, blocks harmful radiation, and keeps Earth's surface at a livable average temperature (~15°C) via the greenhouse effect. Flight: Birds, planes, and helicopters rely on aerodynamic lift generated by moving through air. Bernoulli's principle and Newton's laws explain it. Fun & Surprising Facts A single breath of air contains more molecules than there are breaths in Earth's atmosphere — meaning you’ve likely inhaled a molecule exhaled by Julius Caesar or dinosaurs (statistically speaking). Air is mostly empty space at the molecular level. Gas molecules are tiny compared to the distances between them. Cold air is denser than warm air, which is why hot air rises (convection) and why hot air balloons work. Smell travels on air via volatile molecules. Without air (or another medium), there would be no smell or sound. Liquid air: If you cool air to around -196°C, it becomes a liquid. Liquid nitrogen (a major component) is used for cryogenics and special effects. Weight of air: The total mass of Earth's atmosphere is about 5.15 × 10¹⁸ kg — roughly equivalent to 1 million Great Pyramids of Giza per square kilometer of surface, but spread out. Historically, people didn't always realize air was a "thing." Ancient Greeks thought air was one of the four classical elements. Scientists like Priestley, Lavoisier, and Boyle figured out its composition in the 1700s–1800s. Human Impact Air pollution (particulates, NOx, SO₂, ozone at ground level, etc.) causes millions of premature deaths yearly. Climate change is driven largely by increasing greenhouse gases (CO₂, methane) trapping more heat. On the positive side, the Montreal Protocol successfully healed the ozone layer by banning CFCs.
