![]() ![]() The length of the cycle is about eleven years on average. This rise and fall in sunspot counts is a cycle. Is there a cycle to sunspot activity and if so what is it? The number of sunspots seen on the "surface" of the Sun changes from year to year. A number of UV changes with the solar cycle as well. How is solar activity and sunspot activity related? They increase the likelihood of damaging solar flares. Since the gaseous sphere of the Sun rotates more quickly at its equator than at its poles, the Sun's overall magnetic field becomes distorted and twisted over time. What is unusual about the magnetic field in a sunspot? Sunspots are caused by very strong magnetic fields on the Sun. Outer layers are the Photosphere, the Chromosphere, the Transition Region and the Corona. Inner layers are the Core, Radiative Zone and Convection Zone. The energy itself comes from some of the mass deteriorating into photons. Energy is released because two hydrogen atoms have more energy than one helium atom, and when they bind the excess is released into space. Part Two: When fusion occurs in the sun, its due to quantum tunneling causing hydrogen atoms to bind, forming helium. Part One: Nuclear fusion is the process in which two atomic nuclei are fused together into a larger single nucleus, releasing energy in the process Explain the process of nuclear fusion and how that leads to energy getting to Earth. Our climate is also strongly affected by the amount of solar radiation received at Earth 14. This energy to the atmosphere is one of the primary drivers our weather. The Sun warms our planet, heating the surface, the oceans and the atmosphere. The natural structure of our solar system is held together by gravity 13. This is because they would likely be smashed by their moons. All of our planets that have moons, would be destroyed without gravity. If there was no gravitational force on planets, people would float off into the sky. It constantly pulls, and the objects constantly speed up The Earth's gravitational force accelerates objects when they fall. As the Moon passes over the ocean, there is a swell in the sea level.Īlthough the gravitational force the Earth exerts on the objects is different, their masses are just as different, so the effect we observe (acceleration) is the same for each. ![]() The Moon's gravity pulls on the Earth and makes the tides rise and fall every day. The motion of the Moon is affected by the gravity of the Sun AND the Earth. The Sun's gravitational pull keeps our planet orbiting the Sun. Explain the effects of gravity on the Sun, Earth and solar system. orbit around Sun, with inertia & gravity balance 12. developed by accretion from planetesimals/protoplanets a thick layer of ice surrounding the core gravity wasn't strong enough to hold dense gases contain larger amounts of heavy elements (iron & nickel) Compare and contrast inner planets and outer planets. ![]()
