What is the process in which sun rays reach the Earth?

Answer 1

RadiationHeat can't travel through a vacuum, directly, so the sun emits energy as light. The earth receives about a two billionth of the sunlight emitted, but the light is converted to heat and other energy forms.

Answer 2

The sun's radiant energy reaches the earth's surface either directly through radiation, indirectly through convection, or it can move "across" or "through" objects or materials on the surface via conduction. Let's look more closely at each case.

We've probably experienced the feeling of "warmth" of the sun on our skin on a sunny day. Light energy from the sun is reaching us across space and down through the atmosphere through radiation. A dark colored vehicle in the sun quickly becomes warm (or hot!) to the touch because of radiation.

The light energy from the sun heats the air in the earth's atmosphere, and this drives convection and transfers thermal energy around. It is possible that we've felt a "hot breeze" on our skin on sunny days. The thermal energy in the air will be carried to objects in its path, and it will warm them.

Some conduction will also take place, too. A steel beam in a storage yard that is half in the sun and half in the shade will collect radiant energy from the sun and, through conduction, warm the rest of the beam. Other things on earth can conduct energy this way, and water is warmed by a mixture of radiation, convection and conduction, which represent all the three forms of heat transfer.

Answer 3

Sun rays reach the Earth through a process called radiation. The Sun emits electromagnetic radiation, which includes visible light, ultraviolet radiation, and infrared radiation. These rays travel through the vacuum of space and reach the Earth, where they provide heat and light.

Answer 4

There are two. The radiative zone is inside and extends from around the core out about three quarters of the way to the surface. Energy from the core travels by radiation out through this area to the next area - the convection zone. Energy leaves the radiative zone and travels on out by convection through the convection zone to get to the surface. You need a link, and we got one for ya to the Wikipedia article on the sun.

Answer 5

Radiation!

It's a type of heat transfer that does not require a medium, thus heat from the Sun can move through vacuum to reach the Earth.

Radiation, the beams carry heat energy to the earth (:

Answer 6

Sun rays cannot enter the Earth's atmosphere, the ozone layer reflected the rays, but a chemical called CFCs destroyed part of the layer and caused skin cancer on human. There's a big ozone hole that is almost the same size of the Antarctica at the top of the south pole.

Answer:

The electromagnetic radiation from the sun (light) gan generally pass through the atmosphere unimpeded. Tje ozone in the upper levels of the atmosphere block some, but not all, of the ultraviolet radiation. The greenhouse gases absorb some of the light and convert it to infrared radiation.

Answer 7

Sunlight is a form of electromagnetic energy, and it travels through space at the speed of light unless it encounters an obstacle with which it has an electromagnetic interaction. Since the space between the sun and the Earth is almost entirely empty, sunlight can easily travel through it. To a large extent science describes how things happen rather than why. Electromagnetism functions in accordance with certain basic laws, such as Coulomb's Law and the Maxwell Equations. We cannot really say why the universe operates in accordance with those laws, that's just the way it is.

Answer 8

Solar energy, or light, is both a particle and wave. Therefor it carries itself to the surface of the earth and other celestial bodies.

Answer 9

Energy from the sun reaches the earth via the proces of radiation. And it is through radiation that reflected energy from the earth reaches the sun.

Answer 10

By means of the process of electromagnetic radiation.
