How do humans thermoregulate in cold and warm situations?
In cold situations, the human body shivers to produce heat and the blood vessels constrict to retain heat, in hot situations the human body sweats to release heat. These are the ways the body thermoregulates.
Why does a greenhouse stay warm Evan on the coldest days of winter?
Greenhouse allow solar radiation pass through the windows while it prevent convection heat loss from wind and result is higher temperature in Greenhouse.
What does the greenhouse effect refer to?
Global Warming and Heat
What is a greenhouse and how does it work?
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.
Does saltwater prove to retain heat the best or freshwater?
Answer: Pure water has the best capacity for heat of any material known to man, so any impurity must reduce its ability.
What causes the earth to retain heat and could cause the ice caps to melt?
greenhouse
Can a planet with no atmosphere have a greenhouse effect?
No, a planet without an atmosphere cannot have a greenhouse effect because the atmosphere is necessary to trap heat and create the warming effect. Without an atmosphere, there is no mechanism to retain heat and create the greenhouse effect.
How is global warming working?
The greenhouse effect is the trapping of heat by certain gases that have been identified as helping retain heat on our planet. The runaway greenhouse effect is causing global warming.
What do you call gases that retain heat within the atmosphere?
Greenhouse gases trap heat in the Earth's atmosphere, contributing to the greenhouse effect and potentially leading to global warming. Examples of greenhouse gases include carbon dioxide, methane, and water vapor.
What do greenhouse gases in the atmosphere absorb and retain?
Greenhouse gases in the atmosphere absorb and retain heat energy from the sun that would otherwise escape into space, leading to an increase in the Earth's surface temperature. This process is known as the greenhouse effect and is essential for supporting life on Earth, but human activities have significantly increased the concentration of these gases, causing global warming and climate change.
How do greenhouse gases absorb infrared radiation?
Greenhouse gases absorb infrared radiation by trapping and re-emitting heat energy in the Earth's atmosphere. This process allows them to retain heat and contribute to the warming of the planet.
What is greenhouse gas?
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).
What is the process called in which water vapor and carbon dioxide retain heat?
The process is called the greenhouse effect. Water vapor and carbon dioxide in the atmosphere trap heat from the sun, leading to the warming of the Earth's surface.
What is the meaning of Greenhouse in 'greenhouse effect'?
A greenhouse, or a glasshouse in a garden keeps the air inside warmer. Gardeners use greenhouses to grow fruit etc in cold climates. It gives its name to the greenhouse effect because greenhouse gases retain the sun's heat and keep the earth warm.
Does a planet have to have an atmosphere to have a greenhouse effect?
Yes, an atmosphere is necessary for a planet to have a greenhouse effect. The atmosphere traps heat from the planet's surface, creating a warming effect similar to a greenhouse. Without an atmosphere, there would be no mechanism to retain and redistribute heat, leading to extreme temperature fluctuations.
Do greenhouse gases stop the earth from freezing?
They do. Greenhouse gases in the atmosphere retain heat rising from the surface of the earth and stop it escaping into space. This keeps the earth comfortably warm and has done for thousands of years.
Why this type of heat transfered is trapped by green houses?
Greenhouse gases, such as carbon dioxide and methane, allow sunlight to pass through and warm the Earth's surface. When this heat is radiated back towards space, greenhouse gases trap some of it, causing the atmosphere to retain more heat. This process is known as the greenhouse effect and is responsible for the warming of the Earth's climate.
