Composition and structure of the atmosphere

earth mineral composition

These solid and liquid particles are of great climatic significance. Within the troposphere, temperature decreases with increasing height at an average rate of about Together, these three gases account for This gaseous cover of the earth is known as the atmosphere.

Atmospheric pressure is the total weight of the air above unit area at the point where the pressure is measured. It helps in stopping the ultraviolet rays harmful to the life and maintains the suitable temperature necessary for life. Because carbon dioxide is a greenhouse gas, it acts to trap infrared heat energy radiated by Earth, warming up the atmosphere.

The ionosphere is a region enriched in free electrons and positive ions. Raindrops suspended in a cloud are about 0. Thus, the lowest part of the troposphere i. Ozone 03 Ozone 03 is another important gas in the atmosphere, which is actually a type of oxygen molecule consisting of three, instead of two, atoms.

Because the Sun is close to the horizon, the Sun's rays pass through more atmosphere than normal to reach your eye. Raindrops suspended in a cloud are about 0.

Here they run into strong stratospheric winds, which may shear off the top of the clouds and stop their growth. As another example, due to a phenomenon called Rayleigh scatteringshorter blue wavelengths scatter more easily than longer red wavelengths.

Why do I care? Thermosphere The thermosphere is the second-highest layer of Earth's atmosphere. Though temperature is high, the atmosphere is extremely rarified — gas molecules are spaced hundreds of kilometers apart.

The troposphere is the theatre for weather because all cyclones, anticyclones, storms and precipitation occur here, as all water vapours and solid particles lie within this.

The carbon dioxide that remained began to be used by early plant life in the process of photosynthesis. This region of increasing temperatures is the stratosphere, spanning a pressure range from millibars at its base to about 10 millibars at the stratopause, the top of the layer.THE EARTH’S ATMOSPHERE A.

Viewed from Earth, Saturn has an overall hazy yellow-brown appearance. The surface that is seen through telescopes and in spacecraft images is actually a complex of cloud layers decorated by many small-scale features, such as red, brown, and white spots, bands, eddies, and vortices, that vary.
