Document Summary
The solar system, sun and earth o o. Solar system more than halfway out from center in orion spur of sagittarius. Our solar system made from nebula, cloud of dust and gas. Planetesimal hypothesis (dust-cloud hypothesis) explain how suns condense from nebular clouds o. Solar e: from sun to earth o o o o. Fusion: pairs of hydrogen nuclei joined together freeing energy. Solar minimum: period of years when few sunspots are visible. Solar flares: magnetic storms that cause surface explosions. The sun emitting clouds of electrically charges particles. Originate from sun"s hot solar corona (outer atmosphere) Deflects solar wind toward both of earth"s poles. Incoming e at the top of the atmosphere. Caused by different angles solar rays meet surface. Subsolar point: only point where insolation arrives perpendicular to surface. Balance between incoming shortwave e from sun and outgoing radiation from earth. Refers to seasonal variation of sun"s position above horizon and change of day lengths.
