Clouds move due to the combination of wind, temperature, and pressure differences in the atmosphere.

• Clouds are carried along by the wind in the atmosphere.

• Temperature differences cause air to rise or sink, affecting cloud movement.

• Pressure variations also play a role in cloud motion.

• For example, warm air rising from the ground can create cumulus clouds that move with the wind.

Space is empty due to the extremely low density of matter and the vast distances between objects.

• Space is mostly empty because of the low density of matter in the universe.

• The vast distances between celestial bodies also contribute to the emptiness of space.

• Even though space is not completely empty and contains various particles and radiation, it is considered a vacuum due to the low density of matter.

Gases in the atmosphere do not separate out according to mass due to the constant mixing caused by wind and turbulence.

• Constant mixing caused by wind and turbulence prevents gases from separating based on mass

• Gravity also plays a role in keeping gases well-mixed in the atmosphere

• Different gases have different molecular weights but are still evenly distributed in the atmosphere

The atmosphere gradually thins out as altitude increases, eventually merging into outer space.

• The atmosphere is composed of several layers, with the exosphere being the outermost layer before transitioning into space.

• The Kármán line, located at an altitude of 100 km (62 miles) above sea level, is often considered the boundary between Earth's atmosphere and outer space.

• Beyond the Kármán line, the atmosphere becomes extr...read more

Air mainly contains water vapor due to the evaporation of water bodies, plants, and human activities.

• Water vapor is the most abundant gas in the atmosphere due to evaporation from oceans, lakes, rivers, and plants.

• Other vapors like alcohol, gasoline, or perfume are present in the air but in much lower concentrations compared to water vapor.

• Water vapor is constantly being added to the air through processes like transpir...read more
