How do convection conduction and radiation differ?
Those are three different means by which heat can travel. In convection, heat is carried by moving matter. In conduction, heat is transferred by means of a physical contact between two objects of different temperature. With radiation, energy is emitted in the form of electromagnetic radiation, usually in the infrared spectrum.
Objects that absorb electromagnetic radiation receive?
It receives energy.
Does infrared pick up heat?
Yes, infrared radiation can detect heat. Infrared sensors are designed to detect and measure the infrared radiation emitted by objects, including heat emitted by living organisms or warm objects.
What types of objects emit electromagnetic radiation?
Electric and Magnetic Charges.
Is infrared radiation only emitted from the center of hot solid objects?
No. While most infrared radiation is from the center of hot solid objects, some of it is not. The sun is plasma (not solid) and it emits infrared radiation. Also, infrared radiation can be emitted by the friction in between objects
Why is the electromagnetic spectrum such as radio waves used to study space?
Most stars and many other objects in space emit radio and microwave radiation. Even the big bag emitted electromagnetic radiation.

Thermal radiation refers to waves that travel through the earth?
is emitted from objects on earth by electromagnetic waves (infrared rays) of low energy content (therefore, containing less heat) due to the temperature (internal energy) of the object.

What small objects generate electromagnetic radiation?
Electron release electromagnetic radiation when they lose energy.
Which part of electromagnetic spectrum is emitted by warm objects?
IR, mostly.
Are the radiation wavelengths emitted by the sun longer than those emitted by the earth?
The radiation emitted by the Earth peaks around 10 microns, whereas that from the sun peaks under 1 micron. This is why Earth's radiation is referred to as longwave and solar radiation as shortwave, commonly. All objects emit radiation because all objects have a temperature. In fact, using Wien's Law you can very simply calculate the wavelength, lambda, of maximum emission: lamda(max) = c/T where c is a constant (2897) and T is the temperature of the emitting surface in Kelvin.

What tranfers thermal energy when objects are heated by radiation?
In that case, the energy is transferred through electromagnetic waves. For example, at room temperature that would be infrared.
What types of objects emit electromagnetic radiation?
Electric and Magnetic Charges.
What does an infrared satellite image show?
radiation emitted by objects during the day and night
