Does infrared radiation reach earth?
Much of it is captured by the greenhouse gases, which hold the heat and prevent it escaping into space. As we add more and more greenhouse gases, they are able to hold more heat. This is how we are causing global warming.
Is it true the heat from the sun reaches earth through convection?
No that is not true, heat from the Sun does not reach the Earth by means of convection.
What type of heat transfer allows the Sun's heat to reach the Earth?
Radiation .
Rising warm air transports heat energy by?
Thermal energy travels by conduction, convection, and radiation. Conduction occurs when two or more objects of different temperatures are touching each other. The heat flows from the warmer object to the cooler object, until the objects reach equal temperatures. Convection is the transfer of thermal energy through a moving liquid or gas. Radiation is the transfer of thermal energy though matter and space.
What is one example of heat transfer through radiation?
Heat transfer through radiation is probably best illustrated by the warming of the earth by the sun. Electromagnetic energy from the sun in the form of light travels through the vacuum of space to reach the earth and warm us.
Is a telescope on a satellite made to detect x-rays?
Some of them are. Also, to detect other radiation that doesn't reach Earth, or hardly reaches it - like infrared for example.Some of them are.

Is infrared radiation able to reach us from sun?
Yes, even though some of it doesn't reach the surface of Earth because of the atmosphere. Infrared radiation from the Sun is the warmth you feel on your face when you stand outside on a clear, sunny day. It's what warms the air before you breathe, it's what melts the ice and snow in the Spring, and it's the source of the heat of the oceans.
What does solar energy reach earth by?
Solar energy reaches the earth by two means, Electricity and Gravity.
What kind of radiation passes through the atmosphere and reaches the earths surface?
highlight factors which show that heat from the sun does reach th earth surface by convection
Does heat reach us from the sun by convection?
Heat from the sun reaches Earth by radiation. Convection involves air movement, so heat from a forced air furnace would be an example of convection, as would heat in a convection oven which is basically a regular oven with a fan to distribute the heat more evenly.
Is it true the heat from the sun reaches earth through convection?
No that is not true, heat from the Sun does not reach the Earth by means of convection.
What two processes allow energy generated in the sun to reach the outer layers?
Convection and radiation.
How does the suns energy reach Earth?
Waves of heat and light, called radiation, travel to earth.
When did the infrared rays that reach the earth leave the sun?
About 8 minutes ago.
Is the suns energy radiant?
Yes. Here's a logical proof: There are three ways to transfer energy from place to place: --Conduction, --Convection, --Radiation. Conduction and convection need a 'medium' ... a substance to conduct or convect through. Radiation doesn't need anything to travel through. There is no medium ... no substance ... in the space between the sun and the earth, but heat and light from the sun reach the earth constantly. Since there is no medium for it to travel through, it can't be getting here by means of conduction or convection. The only possibility is radiation.
How much of the Sun's radiation doesn't even reach Earth's surface?
gamma radiation
