How Mch Energy Is Recieved When The Sun Is Perpindicular To The Earth? (Solution found)

In a 12-hour period, how much energy is generated by the Sun?

  • (Due to the fact that mW = mJ/sec). Considering that the sun is always directly above, the amount of energy incident onto a 1 cm 2 solar collector oriented perpendicular to the sun’s beams in 12 hours is (137 mW/cm 2) x (1 cm 2) x (4.3 x 104) seconds = 5.9 x 106 millijoules (mJ).

How is the sun’s energy received on Earth?

Considering that mW equals millijoules per second, this is a valid assumption. Considering that the sun is always directly above, the amount of energy incident onto a 1 cm 2 solar collector oriented perpendicular to the sun’s beams in 12 hours is (137 mW/cm 2) x (1 cm 2) x (4.3 x 104) seconds = 5.9 x 106 millijoules (mJ);

How does the amount of heat received by the Earth from the sun able it to support life?

The sun emits energy in all directions at the same time. The precise balance between the amount of heat that Earth gets from the sun and the amount of heat that Earth emits back into space is what allows the globe to support life on the surface of the planet.

What happens to the sun’s energy on the way down to Earth?

Shortwave light and ultraviolet radiation are emitted by the Sun as a result of the release of energy. Some of the radiation reaches the Earth’s surface and is reflected back into space by clouds, while some is absorbed by the atmosphere and some is absorbed at the Earth’s surface.

How is energy from the sun distributed around Earth?

Winds, precipitation, and evaporation processes, on the other hand, are responsible for distributing the energy produced by the sun throughout the Earth’s atmosphere. The mechanisms of Conduction, Convection, and Radiation are responsible for the transmission of heat energy.

What percentage of the sun energy reaches Earth?

Only one one-billionth of the Sun’s total energy output makes it to the surface of the planet. Clouds reflect little less than one-third of all the energy that does reach the Earth’s surface back into space. 66 percent of the Earth’s surface is reflected back into space by the Earth itself.

How is heat energy received by the atmosphere and redistributed to the Earth?

Where does the energy that powers the atmosphere come from? The atmosphere directly absorbs around 23 percent of incoming sunlight, with the remaining energy being transported from the Earth’s surface by evaporation (25 percent), convection (5 percent), and thermal infrared radiation (the other 5 percent) (a net of 5-6 percent ).

How does the sun provide energy?

Solar energy is produced through nuclear fusion, which occurs in the sun’s atmosphere. Fusion happens when protons from hydrogen atoms clash violently in the sun’s core and fuse to form a helium atom. Fusion occurs when protons from hydrogen atoms violently collide and fuse to form a helium atom. The energy released by this process, which is known as a PP chain reaction or proton-proton chain reaction, is immense.

How does the energy from the sun?

Nuclear fusion, which occurs in the sun, is responsible for the generation of energy. Nuclei are separated from their electrons when nuclear fusion occurs at the sun’s core, due to the extreme pressure and temperature present there. The fusion of two hydrogen nuclei results in the formation of a single helium atom. The sun generates more energy in an hour than the entire country of the United States consumes in a year!

How much energy does the sun produce?

Nuclear fusion is the method through which the sun creates energy. Nuclei are separated from their electrons when nuclear fusion occurs at the sun’s core, due to the extreme pressure and temperature. One helium atom is formed when two hydrogen nuclei combine. More energy is produced by the sun in an hour than the entire country of the United States can use in a year!

How does the energy from the sun interacts with the atmosphere?

Molecular scattering is another way through which the atmosphere interacts with the radiation that enters the atmosphere. Light rays are extremely tiny in size. As light from the Sun enters the atmosphere, these tiny molecules disperse the light. Rayleigh scattering is the term used by scientists to describe this phenomenon.

Which of the following absorb the energy from the sun?

Water vapor, dust, and ozone absorb around 23 percent of incoming solar energy in the atmosphere, while the remaining 48 percent passes through the atmosphere and is absorbed by the surface. As a result, the Earth’s system absorbs around 71 percent of the entire solar energy that arrives.

Why is thermal energy from the sun transferred to Earth?

Electromagnetic waves, often known as radiation, are responsible for the transmission of energy from the sun to the Earth. The vast majority of the energy that travels through the upper atmosphere and reaches the Earth’s surface comes in the form of visible and infrared light, respectively. Radiation, conduction, and convection are the three processes that can transport energy between two points in space.

How is thermal energy in the ocean distributed around the Earth?

Currents of warm and cold water circulate across the ocean, transporting heat from the polar regions to tropical areas and cooling them down, so impacting weather and climate in both directions at the same time. Not only does the ocean retain solar energy, but it also contributes to the distribution of heat around the world.
