Earth seasons are caused because of earths tilt on its axis and it position to the sun. When the earth is at a certain point in its orbit its tilted a certain way. That certain tilt makes it so more or less direct sunlight hits the earth. When more direct sunlight hits the earths northern hemisphere it is summer in the northern hemisphere. When more direct sunlight hits the southern hemisphere the southern hemisphere gets summer. That is the reason for earths seasons!

Persective

Zoom by Istvan Banyai was a very interesting book. It started as a very close up view of a roosters crown but eventually zoomed into space. I thought for sure the first picture was a dinosaurs foot. It taught me that even though you may think something is one thing it turns out to be another. That is basically what perspective is all about.
An example of perspective : one day my friend hit me in the face. I immediately thought he did it to be mean. After asking why he hit me he told me there was a fly. That one little detail widened my perspective. Perspectives can change just like that.
In the field of science perspective is not just a term it can also be different studies. Astronomers use far away perspectives. While doctors may need a microscope to see what there studying. As astronomers we need perspective to even imagine just one solar system let alone the galaxy. In astronomy perspective is huge.
