Heating of the earth, which in turn heats the atmosphere, is responsible for the motions and movements of the air in the atmosphere . The faster molecules move, the hotter the air. ... Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward.
How does temperature affect the atmosphere?
Temperature, Sunlight, and Humidity. Air temperature affects the movement of air , and thus the movement of air pollution. ... The warmer, lighter air at the surface rises, and the cooler, heavier air in the upper troposphere sinks. This is known as convection and it moves pollutants from the ground to higher altitudes.

Why is heat important in the atmosphere?
When the molecules return to a liquid state the latent heat is released as sensible heat (heat you can feel basically). It is important in the atmosphere because it is the primary factor involved in the formation of convective clouds and the stability/instability of the atmosphere .
What happens when the atmosphere is heated?
This bubble of air rises into the atmosphere . As it rises, the bubble cools with the heat contained in the bubble moving into the atmosphere. As the hot air mass rises, the air is replaced by the surrounding cooler, more dense air, what we feel as wind.
What are the harmful effects of heat?
Extreme heat events can be dangerous to health – even fatal. These events result in increased hospital admissions for heat- related illness, as well as cardiovascular and respiratory disorders. Extreme heat events can trigger a variety of heat stress conditions, such as heat stroke .
Which warms up faster land of water?
Water reflects most solar radiation that reaches its surface back to the atmosphere. Since land absorbs more solar radiation the land surface retains more heat as do the vegetation for energy. Thus, land surfaces warm more quickly than water.
How does rain affect the atmosphere?
As a raindrop falls through the atmosphere, it can attract tens to hundreds of tiny aerosol particles to its surface before hitting the ground. The process by which droplets and aerosols attract is coagulation, a natural phenomenon that can act to clear the air of pollutants like soot, sulfates, and organic particles.
What is the impact of the atmosphere?
Not only does it contain the oxygen we need to live, but it also protects us from harmful ultraviolet solar radiation. It creates the pressure without which liquid water couldn’t exist on our planet’s surface. And it warms our planet and keeps temperatures habitable for our living Earth.
Would a person burn up in the atmosphere?
Short answer: Yes , as long as you’re going slow enough. Long answer: Great question! In theory, you could make a ‘cold’ re-entry. The reason that things like satellites and asteroids burn up is because they have huge velocities when they enter the atmosphere; I’m talking astronomical speeds, like kilometers per second.
How does heat escape the atmosphere?
Latent heat, along with birds, ride those rising columns of air. This brings up a third and the ultimate mechanism by which the Earth’s heat escapes into space, which is electromagnetic radiation . Every object, including the Earth’s surface, absorbs and radiates heat electromagnetically. The atmosphere does the same.
What is heating the atmosphere?
Due to the chemical composition of the earth’s atmosphere, most of the infrared radiation emitted by the warm surface never reaches space. Instead the radiation is reflected or absorbed by compounds known as greenhouse gasses . When these compounds absorb the infrared radiation from the surface, the atmosphere heats up.
What are the four effects of heat?
- Raises the temperature.
- Increases volume.
- Changes state.
- Brings about chemical action.
- Changes physical properties.
How does extreme heat affects our environment?
Extreme heat can increase the risk of other types of disasters . Heat can exacerbate drought, and hot dry conditions can in turn create wildfire conditions. In cities, buildings roads and infrastructure can be heated to 50 to 90 degrees hotter than the air while natural surfaces remain closer to air temperatures.
How does heat affect us?
The longer you spend in the heat, the more serious the effects on your body can be. Increased body temperature can cause heavy sweating, clammy skin, dehydration, tiredness, headache, dizziness, nausea, cramps, and a quick, weak pulse.
