Factors determining the different seasons on earth

Seasons can also be artificially created, like hunting season, which is the time of year a community allows people to hunt certain wild animals. In mid-December, however, it is light for less than 6 hours. Near the Equator, regions typically have alternating rainy and dry seasons. This orbit takes days to complete, and is the reason that humans experience the seasons: winter, spring, summer and fall. Seasons have an enormous influence on vegetation and plant growth. Temperate and Polar regions have four different seasons that rotate throughout every year — spring, summer, fall autumn and winter. Places near the Equator experience little seasonal variation. Meteorological Seasons Meteorologists, scientists who study the weather, divide each of the seasons into three whole months. In Barrow, Alaska, the northernmost city in the U. The seasons are affected by the amount of sunlight solar radiation an area gets throughout the year. As the days grow longer, temperatures rise and plants begin to bud and start their life cycles again. Higher elevations are typically colder, with the highest altitudes having a harder time sustaining life. Some animals grow warmer fur or feathers. For example, areas that are darker with dense vegetation can absorb more heat during the summer months, while areas with ice and snow reflect and lose heat. In early times, people only ate the fruits and vegetables they could store for winter.

Spring Beginning on March 20, spring is marked by longer days and the sun higher in the sky. The seasons, of course, are reversed in the Southern Hemisphere.

how do the four seasons occur

Over time, Earth goes through warming and cooling trends. Summer is the warmest time of the year and has the most daylight, so plants grow quickly. Meteorological Seasons Meteorologists, scientists who study the weather, divide each of the seasons into three whole months.

what causes the seasons to change

The oceanic air masses are much less affected by the seasons because circulations in the upper ocean replenish warm surface water if it has been cooled. The tilt toward the sun is maximized during Northern Hemisphere summer in late June the "summer solstice".

However, with the Earth's tilt, in the Northern Hemisphere, in the summer, the Arctic is tipped so far toward the sun that from March 20th to September 22nd the sun never stops shining there. This means it gets more hours of daylight.
