Question: What is the energy generation mechanism for the sun?

How does the Sun generate energy today?

The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun’s core cause nuclei to separate from their electrons. … The radiant energy travels to the Earth at a speed of 186,000 miles per second, the speed of light.

What process generates the sunspot cycle?

Nuclear fusion is the source of all energy the Sun releases into space. … Solar energy production remains steady because the rate of nuclear fusion is very sensitive to temperature. A slight increase in the Sun’s core temp. would mean a much higher fusion rate.

How is energy produced in sun explain by giving necessary equation?

The proton-proton chain. This is the principle fusion reaction in the Sun. Mass, in the form of hydrogen atoms, is converted to energy as described by Einstein’s formula: E = mc2. … The reactions produce high-energy photons (gamma rays) that move through the “radiative layer” surrounding the core.

How does the sun generate energy today quizlet?

The Sun generates energy primarily by nuclear fission. Nuclear power plants on Earth create energy in the same way as the Sun.

What causes the sun’s heat quizlet?

The source of heat for our planet is the sun. The sun’s energy moves through space, then through the earth’s atmosphere and finally reaches the earth’s surface. The sun’s radiation warms the earth’s atmosphere and surface and becomes heat energy.

What is the cause of sunspots?

Sunspots are caused by disturbances in the Sun’s magnetic field welling up to the photosphere, the Sun’s visible “surface”. The powerful magnetic fields in the vicinity of sunspots produce active regions on the Sun, which in turn frequently spawn disturbances such as solar flares and coronal mass ejections (CMEs).

What is the sunspot cycle quizlet?

solar cycle. Also called the sunspot cycle. An 11-year cycle during which the number of sunspots rises to a maximum or falls to a minimum. The periodic change in the number of sunspots; the cycle is taken as the interval between successive minima and is about 11.1 years.

What is meant by sunspot cycle?

: the time between maxima in the varying numbers of sunspots averaging about 11 years but sometimes being many years shorter or longer.
