What makes up 78 percent of earths atmosphere

However, large amounts of CO 2 are also produced when cars and power plants burn coal, oil, and gasoline. CO 2 is also the most important contributor to human-caused global warming.

Relative humidity is the amount of water that the air can hold before it rains. Humidity in the air is measured with an instrument called a psychrometer. This is called air pressure. You experience high air pressure at sea level because the whole atmosphere is pushing down on you.

The air in our atmosphere acts as insulation, keeping the Earth from getting too cold or too hot. Ozone, another type of gas in the air, also protects us from too much sunlight. Air in the atmosphere can also protect us from meteoroids. Social studies. Ben Davis March 1, What gas makes up 78 of the atmosphere? Which is the warmest layer of the atmosphere? Why is ozone above oxygen? Which atmospheric layer is rich in ozone? Why ozone layer is important for human life describe?

What gases are in the upper atmosphere? What is the upper atmosphere called? The atmosphere is divided into five different layers, based on temperature. The troposphere is thickest at the equator, and much thinner at the North and South Poles. The majority of the mass of the entire atmosphere is contained in the troposphere—between approximately 75 and 80 percent. Temperatures in the troposphere decrease with altitude. It reaches from the top of the troposphere, which is called the tropopause, to an altitude of approximately 50 kilometers 30 miles.

Temperatures in the stratosphere increase with altitude. A high concentration of ozone, a molecule composed of three atoms of oxygen, makes up the ozone layer of the stratosphere. This ozone absorbs some of the incoming solar radiation, shielding life on Earth from potentially harmful ultraviolet UV light, and is responsible for the temperature increase in altitude. The top of the stratosphere is called the stratopause. Temperatures decrease in the mesosphere with altitude.

The thermosphere is located above the mesopause and reaches out to around kilometers miles. Not much is known about the thermosphere except that temperatures increase with altitude. The uppermost layer, that blends with what is considered to be outer space, is the exosphere. Also called a shooting star or falling star. Why nitrogen is more than oxygen in atmosphere? What is the most common element in air? What gases do we inhale? What is a another word for hard worker? What is the main composition of air?
