There are two common meanings of the term "greenhouse effect". There is a "natural" greenhouse effect that keeps the Earth’s climate warm and habitable. There is also the "man-made" greenhouse effect‚ which is the enhancement of Earth’s natural greenhouse effect by the addition of greenhouse gases from the burning of fossil fuels (mainly petroleum‚ coal‚ and natural gas). In order to understand how the greenhouse effect operates‚ we need to first understand "infrared radiation". Greenhouse gases

Two glaciers have gone through this area. There is debate about whether the limestone was scraped clean by the glaciers‚ or whether there remained a thin layer of soil that eroded over time .The land is not suitable for farming as nothing can take root and grow properly.

Little water comes from the dry lowlands across the western and southern portions of the Ganga drainage basin

make it a greater controllable circumstance. Humans have to start to doing their part in reducing their use of carbon dioxide‚ such as buying more fuel efficient cars‚ recycling‚ and making their homes greener. National Geographic explains that “Glaciers are melting‚ sea levels are rising‚ cloud forests are drying‚ and wildlife is scrambling to keep pace It ’s becoming clear that humans have caused most of the past century ’s warming by releasing heat-trapping gases as we power our modern lives.

What Is Global Warming ? Global Warming is the increase of Earth’s average surface temperature due to effect of greenhouse gases‚ such as carbon dioxide emissions from burning fossil fuels or from deforestation‚ which trap heat that would otherwise escape from Earth. Earth’s climate is mostly influenced by the first 6 miles or so of the atmosphere which contains most of the matter making up the atmosphere. This is really a very thin layer if you think about it.

1. There are four eras of Earth’s history they are Precambrian (87.6%)‚ Paleozoic (7.1)%‚ Mesozoic (3.9 %)‚ and Cenozoic (1.4 %) 2. There are four layers and two sub layers. * Inner core is solid metal and made up of nickel and iron * Outer core is made of a liquid molten core of nickel and iron * Mantle is made up of dense and mostly solid silicate rock * Lithosphere is the uppermost layer (100km thick) * Asthenosphere is the layer below the
