definition of greenhouse effect essay

greenhouse effect, a warming of Earth 's surface and troposphere (the lowest layer of the atmosphere) caused by the presence of water vapour, carbon dioxide, methane, and certain other gases in the air. Of those gases, known as greenhouse gases, water vapour has the largest effect. The origins of the term greenhouse effect are unclear.

The greenhouse effect is the process through which heat is trapped near Earth's surface by substances known as 'greenhouse gases.'. Imagine these gases as a cozy blanket enveloping our planet, helping to maintain a warmer temperature than it would have otherwise. Greenhouse gases consist of carbon dioxide, methane, ozone, nitrous oxide ...

Greenhouse gases let the sun's light shine onto Earth's surface, but they trap the heat that reflects back up into the atmosphere. In this way, they act like the insulating glass walls of a greenhouse. The greenhouse effect keeps Earth's climate comfortable. Without it, surface temperatures would be cooler by about 33 degrees Celsius (60 ...

A greenhouse is a house made of glass that can be used to grow plants. The sun's radiations warm the plants and the air inside the greenhouse. The heat trapped inside can't escape out and warms the greenhouse which is essential for the growth of the plants. Same is the case in the earth's atmosphere. During the day the sun heats up the ...

The greenhouse effect on Earth is defined as: "The infrared radiative effect of all infrared absorbing constituents in the atmosphere.Greenhouse gases (GHGs), clouds, and some aerosols absorb terrestrial radiation emitted by the Earth's surface and elsewhere in the atmosphere." [15]: 2232 The enhanced greenhouse effect describes the fact that by increasing the concentration of GHGs in the ...

What Is the Greenhouse Effect? The Short Answer: The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat. This process makes Earth much warmer than it would be without an atmosphere. The greenhouse effect is one of the things that makes Earth a comfortable place to live.

The greenhouse effect occurs in the atmosphere, and is an essential part of How the Earth System Works. Click the image on the left to open the Understanding Global Change Infographic. Locate the greenhouse effect icon and identify other topics that cause changes to, or are affected by, the greenhouse effect.

The greenhouse effect happens when certain gases, which are known as greenhouse gases, accumulate in Earth's atmosphere. Greenhouse gases include carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2 O), ozone (O 3), and fluorinated gases.. Greenhouse gases allow the sun's light to shine onto Earth's surface, and then the gases, such as ozone, trap the heat that reflects back from ...

To get energy or electricity, we burn fossil fuels like coal, oil, and natural gas. This releases carbon dioxide and other greenhouses gases into the atmosphere. The more greenhouses gases we put into the atmosphere, the more heat they absorb—and the warmer our Earth becomes. This is called climate change .

600 Words Essay on Greenhouse Effect. A Greenhouse, as the term suggests, is a structure made of glass which is designed to trap heat inside. Thus, even on cold chilling winter days, there is warmth inside it. Similarly, Earth also traps energy from the Sun and prevents it from escaping back. The greenhouse gases or the molecules present in the ...

Takeaways Increasing Greenhouses Gases Are Warming the Planet Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the "greenhouse effect"1 — warming that results when the atmosphere traps heat radiating from Earth toward space. Life on Earth depends on energy coming from the Sun. About half the light […]

The Greenhouse Effect and Climate Change. Even small increases in temperatures can have huge effects. Perhaps the biggest effect is that glaciers and ice caps melt faster than usual. The meltwater d rains into the oceans. This causes sea levels to rise. Glaciers and ice caps cover about one-tenth of the world's land.

The greenhouse effect, in turn, is one of the leading causes of global warming. The most significant greenhouse gases, according to the Environmental Protection Agency (EPA), are: water vapor (H2O ...

The greenhouse effect describes a similar phenomenon on a planetary scale but, instead of the glass of a greenhouse, certain gases are increasingly raising global temperatures. The surface of the Earth absorbs just under half of the sun's energy, while the atmosphere absorbs 23 per cent, and the rest is reflected back into space. Natural ...

Modern global warming is the result of an increase in magnitude of the so-called greenhouse effect, a warming of Earth's surface and lower atmosphere caused by the presence of water vapour, carbon dioxide, methane, nitrous oxides, and other greenhouse gases. In 2014 the IPCC first reported that concentrations of carbon dioxide, methane, and ...

The enhanced greenhouse effect and climate change. The disruption to Earth's climate equilibrium caused by the increased concentrations of greenhouse gases has led to an increase in the global average surface temperatures. This process is called the enhanced greenhouse effect. While scientists agree that the levels of greenhouse gases and ...

The rise in Earth's average temperature contributed to by human activity is known as global warming. The Greenhouse Effect and Climate Change. Even slight increases in average global temperatures can have huge effects. Perhaps the biggest effect is that glaciers and ice caps melt faster than usual.

The effect of each greenhouse gas on Earth's climate depends on its chemical nature and its relative concentration in the atmosphere.Some gases have a high capacity for absorbing infrared radiation or occur in significant quantities, whereas others have considerably lower capacities for absorption or occur only in trace amounts. Radiative forcing, as defined by the Intergovernmental Panel on ...

The "greenhouse effect" is the warming that happens when certain gases in Earth's atmosphere trap heat. These gases let in light but keep heat from escaping, like the glass walls of a greenhouse ...

This global warming has, in turn, dramatically altered natural cycles and weather patterns, with impacts that include extreme heat, protracted drought, increased flooding, more intense storms, and ...

C ONCLUSION. This document explains that there are well-understood physical mechanisms by which changes in the amounts of greenhouse gases cause climate changes. It discusses the evidence that the concentrations of these gases in the atmosphere have increased and are still increasing rapidly, that climate change is occurring, and that most of ...
