What are solar seasons?
In this regard, what are the two seasons of the sun?
As the bands move within the Sun's northern and southern hemispheres, activity rises to a peak over a period of about 11 months and then begins to wane. The quasi-annual variations can be likened to regions on Earth that have two seasons, such as a rainy season and a dry season, McIntosh said.
Secondly, how does solar radiation affect seasons? Earth Science The seasons on the Earth are not caused by how close the Earth is to the Sun. The reason for the seasons lies in the amount of the Sun's radiation that reaches the Earth. The amount of energy put out by the Sun is a constant. The incoming solar radiation is known as insolation.
Also, why does the Sun have seasons?
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. The North pole always points the same way as the Earth revolves around the Sun. The Earth's movement around the sun causes the seasons.
How do we get seasons on Earth?
The seasons are caused by the tilt of the Earth's rotational axis away or toward the sun as it travels through its year-long path around the sun. The Earth has a tilt of 23.5 degrees relative to the "ecliptic plane" (the imaginary surface formed by it's almost-cicular path around the sun).
