What is the reason of changes of season?
The changing position of the Earth’s tilt is the reason for the differences in temperature and length of daylight that distinguish the seasons. When the Northern Hemisphere of the Earth is leaning toward the sun, it receives direct sunlight.
Why do the 4 seasons happen?
The four seasons happen because of the tilt of the Earth’s axis. At different times of the year, the sun’s rays hit different parts of the globe more directly. The angle of the Earth’s axis tilts the Northern Hemisphere towards the sun during the summer. Without the tilt of the earth’s axis, we wouldn’t have seasons.
How does winter happen?
During the winter, the sun’s rays hit the Earth at a shallow angle. These rays are more spread out, which minimizes the amount of energy that hits any given spot. Also, the long nights and short days prevent the Earth from warming up. Thus, we have winter!
Why is daytime longer than nighttime in summer?
In the summer, days feel longer because the Sun rises earlier in the morning and sets later at night. When the North Pole of the Earth is tilted toward the Sun, we in the northern hemisphere receive more sunlight and it’s summer. As the Earth moves in its orbit, the tilt of the North Pole changes (see diagram).

Why are summer days hot?
During the summer, the sun’s rays hit the Earth at a steep angle. The light does not spread out as much, thus increasing the amount of energy hitting any given spot. Also, the long daylight hours allow the Earth plenty of time to reach warm temperatures.
What is difference between summer and winter?
The summer solstice, also known as estival solstice or midsummer, occurs when one of the Earth’s poles (North pole) has its maximum tilt toward the Sun….Difference Between Summer and Winter Solstice.
| Summer Solstice | Winter Solstice |
|---|---|
| Southern Hemisphere has the shortest night | Southern Hemisphere has the longest days |
What is the reason behind summer and winter?
Because the sun is our source of light, energy and heat, the changing intensity and concentration of its rays give rise to the seasons of winter, spring, summer and fall. The seasons are marked by solstices and equinoxes – astronomical terms that relate to Earth’s tilt.
What causes summer to be hotter than winter?
Contrary to what most people believe, the reason that summer is hotter than winter is not because we are closer to the sun in summer. In fact, in the Northern Hemisphere , the orbit of the earth takes us further from the sun in summer. Summer is hotter than winter due to the tilt in the axis of the earth of 23 degrees.
What is the difference between summer and winter?
There are many differences between summer and winter. One difference is that summer is hot outside and winter is cold. Temperatures in summer can reach over 100 degrees Fahrenheit, while in winter it can be below zero degrees Celsius. During the winter, people can enjoy sledding.
How and why does summer and winter occur?
The tilt of the Earth’s AXIS is the most important reason why seasons occur. We have hot summers and cold winters because of the tilt of the Earth’s axis. The tilt of the Earth means the Earth will lean towards the Sun (Summer) or lean away from the Sun (Winter) 6 months later. In between these, Spring and Autumn will occur.
