Some parts of the world have two seasons: the rainy day or wet season, and the sunny or dry season. Others have four: winter, spring, summer, and fall.
She Philippines experiences two distinct seasons every year because of its location. Since the Philippines is near the equator, it receives direct sunlight, thus it experiences summer or dry season. The Philippines is surrounded by waters–Pacific Ocean, Celebes Sea, and China Sea. Due to the unequal heating of the earth’s surface, rains occur in different portions of the country. It, therefore, has wet or rainy season.
Cause of the Seasons of the Earth
The tilt of the earth’s axis is the cause of the seasons in different places of the earth. If the hemisphere where a place is located tilts toward the sun as the earth revolves, it is summer in that place. The place experiences longer daytime than nighttime.
The Northern Hemisphere experiences summer from June to September. This hemisphere faces toward the sun on June 21 or 22.
As the earth moves, summer turns to autumn. During autumn, the Northern Hemisphere faces neither toward nor away from the sun. The length of days and nights are more or less equal. This happens from September to November.
From December to February, the Southern Hemisphere faces toward the sun and experiences summer. It is now winter in the Northern Hemisphere. Nighttime is longest on December 21 or 22 as the Northern Hemisphere faces away from the sun. Then the first day of spring comes where days and nights are of almost equal length. Spring occurs from March to June. The earth has completed one full revolution around the sun.
Positions of the Earth in Particular Months(March, September, and December)
Note: The earth goes around the sun, or orbits the sun once a year.
The earth turns on its axis once every 24 hours.
In March, the Earth is sideways with respect to the sun and the days and nights are of equal length.
In September, the earth is sideways with respect to the sun and the days and nights are of equal length.
In December, the South Pole is tilted toward the sun. Places in the southern half of the earth have more than 12 hours daylight.
