The Short Answer: “Earth’s tilted axis causes the season. Since the earth is tilted, when the Northern part of earth receives direct sun rays, it causes summer season. And when the Southern part of earth receives direct sun rays, the northern part goes through the winter season.”
To put it frankly, there are polar opposite seasons on both sides of the equator, that are summer and winter, one at a time in each.
Seasons change. The weather changes. The leaves change color. The wind changes direction.
What Is The Definition Of Season?
When we think of a season, we usually think of certain weather conditions and the flora and fauna that are part of that climate. But what we experience as a season is much more than weather and climate. A season is a period of time that is characterized by a distinct sequence of seasons, distinct flora and fauna, and distinct weather patterns, all of which are shaped by the time of year and the location on Earth.
If you’ve ever watched a plant grow, you know that they go through different seasons. The plant might be small and young in the summer, when the sun is high in the sky, but by the time winter comes, the plant is big and strong and ready to bear its burden of snow and ice. I like to think of these seasons in the same way. We humans are complex creatures, and each season is a time in our lives when our complex personalities come more to the surface.
What are some factors over which Seasons depend?
- Axis of Earth
- Sunlight
- Elevation
- Wind patterns
- Rainfall
- Global Warming
How does "Axis Of Earth" affect Season?
Well it is actually all about the tilt in the axis of Earth that causes the change of Season.
Let’s see how it is.
We know our Earth receives heat from the sun's radiation or sun rays. And since our Earth is tilted by 22.5 degrees vertically, not all the regions of Earth will receive the same amount of heat. Therefore, when the northern part (above the equator) is tilted towards the sun, more heat energy is absorbed by the northern region ,resulting in the summer season above the equator countries. And when the southern part (lower the equator) is tilted towards the sun, more heat energy is absorbed by it, resulting in the summer season lower the equator.
And when the northern part is tilted towards the sun, the southern part is tilted away from the sun, resulting in less direct sun rays and total heat which causes the winter season in the southern part and vice versa.
How does "Sunligh" affect Season?
Sunlight or sun rays contains heat energy from the sun that is absorbed by the earth’s surface, hence maintaining the temperature on the earth.
I already said that it is all about the tilt in the axis of earth. Though ‘tilt in axis’ and ‘sunlight’ are being told to you guys separately, the real explanation comes by intervening the two.
Here it is.
Not all regions of earth receive equal amounts of sunlight. So, the regions that receive more sunlight have warmer seasons and regions of the earth that receive less amounts of sunlight have colder seasons.
How does "Elevation" affect Season?
Yeah, elevation affects the season. When we go to higher places such as mountain regions, we get to see colder seasons, while on the plains we get to see relatively warmer seasons.
It is because at higher altitudes, the air pressure is low and the air molecules have lower chances to bump into each other to create extra heat.
How does "Wind Patterns" affect Season?
Wind travels by carrying moisture with it. Hot air currents and cold air currents also flow from one place to another that results in change of weather of that region. But in the long term it actually changes the season, or so I say that it starts a new season.
How does "Rainfall" affect Season?
We all know the word ‘rainy season’, the season in which it rains pretty frequently. Rain affects the atmosphere and environment, it adds tons of moisture and humidity in air thus creating a different or new seasonal change to that region. There are places where it rains all year round and there are also some places where it rains a drop in the name of god.
How does "Global Warming" affect Season?
Global Warming is not actually a natural factor that affects the season, rather we humans added this, maybe because we thought we also need to be on this list that can alter even seasons.
Global warming is a change in the atmosphere caused by the release of carbon dioxide from the surface of the earth. The warming of the atmosphere causes the clouds that are formed over the oceans to change the patterns of the rainfall that fall there. The warmer the atmosphere gets, the more rain falls, and the colder the atmosphere gets, the less rainfall falls. The climate is in a state of change due to the greenhouse effect.
Importance Of Seasonal changes
The change of seasons is significant in many ways. Seasons change the way people live and think. It also changes the way plants and animals grow and behave.
The world looks like a different place during the rainy season. The air is damp and fresh, everything seems so colorful and beautiful. The air smells different, everything smells of rain, the air has so much vitality, the atmosphere is lively, the people are cheerful and the atmosphere is full of energy. In the rainy season, the atmosphere is full of life.
We can say that seasonal changes are the factor that is mostly responsible for the changes in weather and climate. It is because of the change in season that we have different climates and weathers all around the world. We can say that without seasonal changes, the climate and weathers will not be different all around the world.
