Answer:
measures both luminosity and distance
Explanation:
Apparent magnitude (m) is a measure of the brightness of a star or other astronomical object observed from Earth. An object's apparent magnitude depends on its intrinsic luminosity, its distance from Earth, and any extinction of the object's light caused by interstellar dust along the line of sight to the observer.
The oceans are one of the major elements that influence the climate around the globe. They are massive water bodies, being able to accumulate and release enormous amounts of gasses from and into the atmosphere. Also, the ocean waters are an excellent heat storage, as the water has a property to cool down and warm up relatively slowly, so once its warmed up it tends to keep the temperature much higher at the places near the coast. The ocean waters are constantly on the move because of the difference in temperature and density. With the movement of the water they create air masses that follow them, some warm and wet, some cold and dry. The places that are influenced by the oceans have their climates modified mostly by them, with the most common characteristic being that the temperatures extremes are lacking, so the climate tends to be milder in all seasons, or at places it remains the same for the whole year.
