Deforestation also drives climate change. Forest soils are moist‚ but without protection from sun-blocking tree cover they quickly dry out. Trees also help conserve the water cycle by returning water vapor back into the atmosphere. Trees remove carbon dioxide from the atmosphere through photosynthesis. Cutting down forests will cause a decline in photosynthetic activity which results in the

Air molecules push and press on the surfaces they contact. The amount of force per unit area that air molecules exert on a surface is called air pressure. (What is Air Pressure 6) Air pressure is caused by all of the air molecules in the Earth’s atmosphere pressing down on the Earth’s surfaces. We can measure air pressure to help us predict weather conditions around the world. Temperature also affects air pressure because air contracts when it cools and expands when it is heated. So if air above a

That’s why today the contradictions between man and nature are dramatic. People are slowly destroying the nature environment around them. Today we are anxious about the state of the air we breathe because every year world industry throws out into atmosphere about 1 000 million tons of dust‚ smoke and other harmful substances and people of many cities suffer from smog. | Another reason why there is such high level of air pollution in large cities is because of car exhaust fumes from very intensive

in the atmosphere. Some of them get reflected back into space. The ones which get through the atmosphere warm the earth up. All the time‚ the earth radiates heat into space‚ which cools it down. We only really notice this at night‚ when there is no heating from the sun. Some of the heat going out is trapped by the atmosphere. This is what makes our planet warm enough to live on. But if too much heat is trapped‚ our planet will warm up and the climate will change. What is the atmosphere and why

Acid rain is caused by the numerous acidic pollutants‚ which have potential to damage earth’s environment in a drastic way. Acid rain is caused due to the presence of chemicals like Sulfur Dioxide and Nitrogen Oxides in the atmosphere. These chemicals are introduced in the atmosphere as a result of the industrial processes. Sulfur Dioxide is emitted out of those industries that use coal as

shines its rays down on earth giving us heat and reflecting back up into the atmosphere. Kind of like when you shine light in a mirror‚ it reflects back at you. It has been discovered that the Sun’s magnetic field has doubled since 1900. This tells us that changes in the Sun have had a hand in the recent general warming of the earth’s climate. If the sun’s rays come down on earth and are trapped from going back into the atmosphere it causes the temperature to rise and therefore causes numerous issues with

look at the science involved‚ their assertions appear to be groundless. First‚ carbon dioxide is not a pollutant as many claim. Carbon dioxide is good for plant life and is a natural constituent of the atmosphere. During Earth’s long history there has been more and less carbon dioxide in the atmosphere than we see today. Second‚ they claim that climate is stable and slow to change‚ and we are accelerating climate change beyond natural variability. That is also not true. Climate change is generally a

Global Warming The greenhouse effect‚ in environmental science‚ is a popular term for the effect that certain variable constituents of the Earth ’s lower atmosphere have on surface temperatures. It has been known since 1896 that Earth has been warmed by a blanket of gasses (This is called the "greenhouse effect."). The gases--water vapor (H2O)‚ carbon dioxide (CO2)‚ and methane (CH4)--keep ground temperatures at a global average of about 15 degrees C (60 degrees F). Without them the average
