How do thick blankets and heavy coats keep you warm?
Thery don't keep cold out. They prevent Therml Energy from escaping into the air.
Why does putting foam in a gap in a cavity wall keep a house warmer?
Foam will block heat from escaping.
List the energy sources you use everyday?
About every thing you do uses energy. Here are some examples:Run, walk (uses the energy from the food you eat; on the other hand, the following examples use more technological sources of energy)Watch televisionUse the computerDrive a carTurn a light on (or keep it on)
Who where the radiant girls?
The radiant girls were a group of girls hired to paint glow-in-the-dark numerals on watches in the mid 1920's, they were told to keep the paint brushes pointy by licking them after every stroke, what they didn't know was that the chemicals in the glow-in-the-dark paint was harmful if ingested slowly all of the radiant girls began to fall ill with bone cancer and eventually deceased
What is the importance of energy?
A first reason for conserving energy is that we use energy that often comes from the burning of fossil fuels. Industry, transport and the generation of electricity largely use fossil fuels. When these fuels are burned they release carbon dioxide that has been sequestered away for millions of years. This extra CO2 is adding to the greenhouse gases in the atmosphere and contributing to an enhanced greenhouse effect. This is causing the planet to warm up dangerously.Another reason for conserving energy is to save oil. We are often reliant on other countries for oil. If we can find other renewable sources of energy, then we can keep the oil for other uses, like plastics. Soon we will run out of oil and the oil prices will increase as we dig deeper and farther.
Greenhouse gases keep earth warm by?
By trapping the heat rising from the warm earth and preventing it escaping back to space. By absorbing the heat during the daylight hours and releasing it during lower energy periods.
What keeps earth's temperatures from fluctuating?
The greenhouse effect (greenhouse gases in the atmosphere) keep the earth warm enough for life. They prevent some heat escaping out to space, particularly at night.
What energy transformation takes place when a animal eats food so they can keep warm?
Radiant energy to thermal energy
What keeps earth temperature from fluctuating drastically?
The greenhouse effect (greenhouse gases in the atmosphere) keep the earth warm enough for life. They prevent some heat escaping out to space, particularly at night.

How does the atmosphere keep the earths temperature moderate?
The Earth's atmosphere works to keep the planet warm in the same way as a greenhouse. Warmth comes in the form of the sun's rays as it passes through the atmosphere. It is then kept from escaping back into space by greenhouse gases like carbon dioxide, methane and even water vapour.
Greenhouse gases- how do they affect us?
Greenhouse gases have been working with the heat from the sun to keep the earth comfortably warm for millions of years. The gases absorb some of the heat from the warmed earth and keep it from escaping into space. When greenhouse gas levels increase, as they are from recent human activity, they retain more heat and the earth warms up.
How can the greenhouse effect and greenhouse gases cause problems with earths energy budget?
Earth's energy budget has been balanced for thousands of years. The natural greenhouse effect allows enough heat in and out of the atmosphere to keep it warm enough for life. Additional greenhouse gases, which we are now adding to the atmosphere and causing problems with the budget and the earth is warming up. This warming is causing climate change.

What does the term radiant barrier refer to?
Radiant Barrier is a term that is most commonly used to describe a kind of material that is used to help save energy by holding in heat and keeping out cold, yet being able to keep out unwanted heat.
How is heat trapped in a car similar to the greenhouse effect and global warming?
For the greenhouse effect: Solar energy enters the car through the window and is absorbed by the seats and dashboard of the car. The energy is then re-emitted as thermal energy (infrared waves) but is trapped by the glass of the window. The process is very similar to how water vapor and other "greenhouse gases" keep our planet warm enough for abundant life.
