It's a device (structure) that allows heat to get in freely, but holds it in so that the heat builds up.
Classically it is a building with walls and roof made of glass: the sunlight gets in but it's hard for the heat to get out.
The greenhouse allowed them to have fresh vegetables all year long. They had to use a greenhouse to get the flowers to bloom. The greenhouse gases were warming the Earth.
The Greenhouse Effect is real. There is no question that the presence of CO2 and other greenhouse gases keeps this planet comfortably warm. The alarming crisis of Global Warming arises from the ever-increasing concentrations of greenhouse gases in our atmosphere as a direct result of human activity. All of the science suggests that increasing greenhouse gas concentrations will inevitably lead to a rise in global temperature. How much and how quickly temperature will rise is disputed. Nonetheless, as scientists and citizens, we have a responsibility to act now, to educate and work towards changing our habits and our impact on the planet. thanks................
Compared to the external environment, a greenhouse will retain heat.
Greenhouse allow solar radiation pass through the windows while it prevent convection heat loss from wind and result is higher temperature in Greenhouse.
The temperature inside a greenhouse is typically higher than the temperature outside due to the greenhouse effect. Sunlight enters the greenhouse and warms the interior, while the glass or plastic structure traps heat, preventing it from easily escaping. This can lead to temperature differences of 10 to 30 degrees Fahrenheit (about 5 to 15 degrees Celsius) or more, depending on factors like insulation, ventilation, and external weather conditions.
Greenhouse gases work the way blankets work, by keeping heat in.
A botanist will most likely work in a greenhouse or in a dome with alot of plants in it.
A person who works in a greenhouse is typically referred to as a greenhouse worker or greenhouse technician.
Greenhouse gases, like carbon dioxide and methane, trap heat in the Earth's atmosphere by allowing sunlight to enter and warm the planet's surface. When the surface absorbs the sunlight, it emits infrared radiation, which is then trapped by the greenhouse gases. This trapped heat leads to an increase in temperature, known as the greenhouse effect.
Saran wrap helps in creating a greenhouse effect without having an actual greenhouse. The plastic helps keep moisture in and protects the plant from the elements or harshness of a climate.
A carbon offset is a financial tool aimed at a decrease in greenhouse gas emissions. Carbon offsets are measured in metric tons of carbon dioxide-equivalent which can exemplify 6 primary families of greenhouse gas emissions. One carbon offset constitutes the step-down of one tonne of carbonic acid gas or its equal in other greenhouse gases. this text was taken from: www.sofame.com/Carbon-Offsets

What is the causes of greenhouse?
This depends on many factors. It depends on who is going to build the greenhouse. How big the greenhouse will be. Also where the greenhouse if being built.
- to make economy of materials, money work force - to avoid pollution of the earth - to avoid the the greenhouse effect
A greenhouse is simply a protected area in wich you can control weather and temperature to suit the plants you want to grow.
From the Greenhouse was created in 1989.
