How does the theory of plate tectonics relate to present concerns about air pollution and global warming?
The theory of plate tectonics is the concept that Earth's outer shell is divided into several large plates that float on the semi-fluid asthenosphere beneath them. While plate tectonics itself does not directly impact air pollution and global warming, the movement of these plates can influence volcanic activity, which can emit pollutants into the atmosphere. Additionally, the burning of fossil fuels, a major contributor to air pollution and global warming, releases carbon dioxide, a greenhouse gas that can affect Earth's climate and potentially impact tectonic activity.
What layer in the atmosphere do meteors come from?
Meteors originate in the mesosphere, which is the third layer of the Earth's atmosphere located between the stratosphere and the thermosphere. This layer is where most meteors burn up upon entering the atmosphere due to the friction with the air molecules.
Is global warming caused by the sun?
There is a natural greenhouse effect which has kept the earth warm since before life began. This is supported by the carbon and water cycles which move carbon and water in and out of the atmosphere. However, anthropogenic (man-made) global warming is not caused by nature. Man discovered fossil fuels and started seriously burning them 250 years ago, at the start of the Industrial Age. Coal, oil and natural gas have been very useful to power industry, transport and to generate electricity. The big problem is they release carbon dioxide (CO2) which has been buried underground for millions of years. This extra CO2 has overwhelmed the carbon cycle, which has not been able to move the extra out of the atmosphere. CO2 levels were about 270 ppm in 1750 but are now (June 2011) around 394 ppm (parts per million, or 0.0394%), a rise of 40%..
People that believe in global warming?
Have the very slimmest of Hope. That Hope depends, ironically, upon technology. We have lots of Technology so let us Hope and work towards the Day when Technology may undo what technology has done.
What is an outer rise earthquake?
An outer rise earthquake occurs at a subduction zone where the descending tectonic plate bends and flexes, causing stress to build up. When this stress is released, it can result in an earthquake. Outer rise earthquakes usually happen in the deep ocean and are associated with the bending of the subducting plate.
How is global warming affecting your geosphere?
Global warming is impacting the geosphere by causing thermal expansion of the Earth's outer shell, leading to rising sea levels and coastal erosion. It also contributes to the melting of glaciers and permafrost, which can trigger landslides and changes in soil stability. Overall, global warming is altering geosphere processes and dynamics, emphasizing the urgent need for mitigation strategies.
Why the wolrd is going end?
the world will end because of meteors from outer space

What is the trapping of heat near a planet's surface by certain gases in the planet's atmosphere?
We call it the greenhouse effect, which is natural, or the enhanced (or accelerated) greenhouse effect which is causing global warming.
What layer in the atmosphere do meteors come from?
Meteors originate in the mesosphere, which is the third layer of the Earth's atmosphere located between the stratosphere and the thermosphere. This layer is where most meteors burn up upon entering the atmosphere due to the friction with the air molecules.
Why do meteors that fall into the Earth's atmosphere burn up before reaching the ground?
Meteors burn up in the Earth's atmosphere due to the intense friction generated as they travel at high speeds through the air. This friction produces extreme heat, causing the outer layers of the meteor to vaporize and emit light, resulting in the bright streaks we see as shooting stars. Most meteors disintegrate completely before reaching the ground, with only larger fragments surviving the descent as meteorites.
How is global warming affecting the Antarctic glaciers?
The major amount of human activities contribute to Antarctica's global warming. They add excessive amounts of greenhouse gases to the atmosphere. Green house gases pile up in the atmosphere and capture the heat that would, in a normal manner, escape into outer space.
How does carbon dioxide cause global warming?
When fossil fuel is burned, its carbon atoms largely wind up in atmospheric carbon dioxide (CO2) gas. CO2 blocks the ability of the earth to radiate heat in the form of infrared light, which normally penetrates the atmosphere and goes into outer space. Hence the planet retains more heat.Because the carbon in fossil fuels (coal, oil and natural gas) has been hidden away for millions of years, releasing it now is increasing its levels in the atmosphere. More greenhouse gases means more heat is retained. This is causing global warming.
How do greenhouse gases affect Earth environment?
Greenhouse gases (GHG) allows sun radiation to penetrate and reach earth but are insulators to heat to move through into outer space. According GHG contribute to global warming. This global warming could lead to more snow melt down that lead to rise of water levels on earth and possible sinking of low level earth areas under water.
Cant you just compress lots of CO2 into canisters then put them in outer space to reduce global warming?
The power needed for compression, the construction of the canisters and rockets, and the transportation to the launch sites would createmore carbon dioxide than was removed.
Meteors are rocks from outer space that?
fall towards Earth and enter its atmosphere. As they travel through the atmosphere, they heat up and produce a glowing trail of light, known as a meteor or shooting star. Most meteors burn up completely before reaching the surface of the Earth.
What is the link between greenhouse effect and global warming?
Global warming is the direct result of the greenhouse effect. Without carbon dioxide in the atmosphere to act as a greenhouse gas, the world would be some 30 degrees colder than at present and life as we know it would be impossible. So the greenhouse effect is essential for human existence. It is the anthropogenic increase in greenhouse gases that is now causing concern. The present average global temperature is just about right for human comfort and civilisation. Greenhouse gas emissions are contributing to a rise in average global temperatures to a point that will have serious economic and social impacts on our lifestyle.
