How does the ozone layer help in protecting the earth from greenhouse effect?
Ozone layer does not allow UV to pass through which kill the greenhouse gas absorbing plankton. This avoids the greenhouse effect.
Why do you think greenhouse gases get that nickname?
Greenhouse gases get their nickname because, like the glass walls of a greenhouse, they allow sunlight to enter and warm the Earth's surface. However, they also trap some of the heat energy from the sun, leading to an overall warming effect known as the greenhouse effect.
Where do greenhouses gases trap energy?
Greenhouse gases are very light but they change how sunlight is reflected back out into space in that greenhouse gases do not allow as much sunlight to be reflected. This increases the amount of energy held within the atmosphere and warms the planet
What effect does the greenhouse effect have on light entering and leaving the atmosphere?
Greenhouse gases (water, carbon dioxide and methane, mostly) allow light to enter the earth's atmosphere. It comes in as solar radiation and about half of it is absorbed by the earth's surface. This radiation is converted to heat energy, which in turn, radiates infrared (longwave) radiation back out into space. Much of this infrared radiation is captured by the greenhouse gases in the troposphere (the lowest layer of the atmosphere). The warmed greenhouse gases then heat the air around them, and re-radiate the heat back down to earth, contributing to the greenhouse effect.
Why do greenhouse gases trap heat in the Earth's atmosphere?
Greenhouse gases trap heat in the Earth's atmosphere because they allow sunlight to enter and warm the Earth's surface, but they also absorb and re-emit infrared radiation, preventing some of the heat from escaping back into space. This process creates a warming effect known as the greenhouse effect.
What are similarities and differences between an actual greenhouse and greenhouse effect on earth?
Both an actual greenhouse and the greenhouse effect on Earth serve to trap heat, creating a warmer environment. In a greenhouse, glass panels allow sunlight to enter while preventing heat from escaping. Similarly, the Earth's atmosphere contains greenhouse gases that absorb and re-radiate infrared radiation, keeping the planet warm. However, while a greenhouse is a controlled structure designed for plant growth, the greenhouse effect is a natural process that can lead to global warming if excessive greenhouse gases accumulate in the atmosphere.
In what way are greenhouse gases similar to blankets?
Greenhouse gasses allow sunlight into the Earth's atmosphere. Globally, about half of this energy is absorbed by the Earth's surface, and the other half is reflected back into space. When the Earth gives off this heat (in the form of longwave, infrared radiation) it is trapped by the greenhouse gasses. This is the reason that our planet is warm enough to live on, however, scientists believe that it is the basis for the general warming pattern the Earth is currently experiencing.
What can the hole in the ozone allow damage to?
it lets to the ultra violet rays reaching the earth surface causing greenhouse effect and global warming
How does a greenhouse keep radiant my energy from escaping?
A greenhouse keeps radiant energy from escaping by trapping heat from the sun inside its structure. The glass or plastic walls of the greenhouse allow sunlight to enter and warm up the air and plants inside. This creates a greenhouse effect, where heat is absorbed and re-radiated back into the greenhouse, preventing it from escaping easily.
How does the sun help sustain life on earth and how is this related to the earth's natural greenhouse effect?
The sun lights and warms the planet. Greenhouse gases in the atmosphere retain this heat to allow life on earth. The greenhouse effect is driven by the carbon cycle. The sun supports photosynthesis, the process used by green plants and some bacteria to make compounds such as carbohydrates. The sun powers the cycling of matter, it also drives the climate and weather systems that distribute heat and fresh water.
How does water affect the greenhouse effect?
The great sheets of frozen ice and snow in the Arctic and Antarctic regions act to reflect some of the sun's heat back into space, thus keeping the planet cooler. If all this ice and snow disappears the rate of Earth's warming would increase.
What is greenhouse gas effect?
A greenhouse traps the heat inside it so that the temperature inside is hotter than the outside. Sunlight can pass through the panes of the greenhouse to warm and allow photosynthesis, yet it prevents the escape of heat from the greenhouse. Greenhouse Effect references that phenomenon. Greenhouse Gases are the gases that have the similar ability of trapping heat from sun's radiation. Gases include NOx, CO2, CO and the like. Such gases let sunshine pass through but retain and absorb the heat radiated by the earth. It makes the earth hotter due to the trapped heat (greenhouse effect).
