What is the main method of heat transfer in your atmosphere?
it receives it from the sun in forms of electromagnetic waves / or radiation
How will the background radiation a person receives change when they fly in a jet?
At altitude, an individual will enjoy less shielding from radiation by the atmosphere. The person flying is, in general, subject to more radiation that a person on the ground.
What elements are used to make planes fly?
fuel
What do these 3 words have in common weight fly and sand?
The words weight, fly and sand have "fly" in common, because together they can form other words. Their direct relationship is: fly, fly weight, and sand fly.

Why is vacuum a good insulator?
A vacuum is a good insulator because it prevents the transfer of heat by eliminating the medium (matter).A perfect vacuum is the absence of matter. Heat is transferred by conduction, convection and radiation. Radiation is the only form of heat transfer that does not need a medium. Furthermore, radiation is generally the least efficient method of heat transfer.
How do birds use convection currents to fly?
Birds use convection by using convection currents the heat will rise as a draft and then birds can ride the draft to reach higher altitudes.

Why does radioactive source give out radiation?
Radioactive decay happens when an unstable atom cannot hold itself together, and pieces of it fly out. The pieces include the emissions we call radiation.
Why does air temperature changes as you move up from the Earth surface?
The reason is that sunlight gets converted into heat mainly at the Earth's surface, only conduction and some re-radiation heat the air and that occurs mainly near the ground. *If you fly on a plane with an outside temperature display, it's not uncommon to see temperatures of -50°C or -60°C at cruising altitude.

What is found in the stratosphere and protects the earth from the suns radiation?
Ozone, an unusual type of oxygen molecule that is relatively abundant in the stratosphere, heats this layer as it absorbs energy from incoming ultraviolet radiation from the sun. Which is the complete opposite of the behavior in the troposphere where temperatures drop with the increase in altitude. Because of this temperature stratification, there is little convection and mixing in the stratosphere, so the layers of the air are quite stable. Commercial jet aircraft fly in the lower stratosphere to avoid turbulence which is common in the troposphere below.
Why vacuum is a insulator?
There are four methods by which heat transfers from one area to another. They are, evaporation, convection, radiation and conduction. With a vacuum, only radiation can transfer heat across the vacuum and because the other three forms of heat transfer are negated that makes a vacuum a good insulator. Then again, you may be referring to electricity. For electricity, negative and positive ions in a liquid or electrons in a solid, need a medium to travel through. Electrons in a solid for example need to jump from atom to atom as they move or conduct through the solid. If you have a vacuum it makes it very difficult for electrons and or ions to jump across the vacuum. They will fly across a vacuum if the voltage is high enough though. What's more is, you can help electrons to fly across a vacuum if you heat up the cathode (negative electrode) to a very high temperature, but still, you also need a high voltage to pull them across the space of the vacuum after they fly off the cathode via heating. And so, a vacuum is a very good insulator for electricity at room temperature and moderate voltages.
When fly is used in present tense how do you spell it?
I fly, he/she flies
What was the eagle used for?
To fly.
Did kiwis used to fly?
No
