Earth's atmosphere gases percentage
The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth creates pressure, absorbs most meteoroids and ultraviolet solar radiation, warms the surface through heat retention (greenhouse effect), allowing life and liquid water to exist on the Earth's surface, and reduces … WebThe large growth in global CO 2 emissions has had a significant impact on the concentrations of CO 2 in Earth’s atmosphere. If we look at atmospheric concentrations over the past 2000 years, we see that levels were fairly stable at 270 to 285 parts per million (ppm) until the 18 th century.
