Seasons
Seasons are caused by the tilt of Earth's axis as it revolves around the sun. During the Summer the Sun's rays are more direct. Also, the Sun is higher in the sky and the days are longer. When it's Autumn or Spring, daytime hours and nighttime hours are relatively equal. In the winter, there is very little direct sunlight and the days are shorter. as the Earth moves around the sun, the place on earth that receives the most direct sunlight changes. The more direct sunlight, the higher the solar energy, and the hotter the weather.

Perspective
The book zoom by Istvan Banyal shows perspective in an unusual way. Each picture zooms out from the previous picture, giving you a broader idea of what is happening. The picture would have clues of what the next picture will be, but it's still difficult to guess. It shows that to gain a better perspective, you have to look at the big picture. There is almost always smaller details and almost always a bigger idea.
Many times you think you are seeing something accurately, but when you change your perspective you see it differently. An example is that my sister gave me a puzzle that had five towers. You had to draw two lines to "complete the pattern." Then my sister gave me a clue, "think in perspective." when you flip the picture over, the tops of the towers become the letters U, V, W, and Y. One tower doesn't have a letter. Adding to lines to the top of that tower to make an X completes the pattern. To alter your perspective you can change the way you are looking at something, like turning it upside down. Experience and knowledge can also change your perspective.
Someone that is interested in close-up data is gathering information from a small field of information. Someone interested in gathering data from a larger perspective might be studying a big idea. In Astronomy it might be important to be aware of perspective because space and everything in it are so gigantic. Small details don't seem as important whan something so large. Although, sometimes it's important to slow down and take a closer look at something.
