Why do the season changes?

Answer 1

Seasons change because the axis of the earth is tilted by 23.5 degrees (from a line perpendicular to its orbit). As the earth moves around its orbit there is a time when it is tilted towards the sun and so receives a higher concentration of the sun's energy (summer) and a time when it is tilted away and receiving less energy (winter). This also explains why it is summer in N hemisphere when it is winter in S hemisphere.

Answer 2

As you may know from your Middle/High School science classes, Earth revolves around the sun on it's axis of about 24 degrees. Because of this rotation, we have what are called Solstices and Equinoxes, a solstice being when the sun is the furthest northern or southern point twice a year, and an equinox being when night and day are the exact same length. The reason we have seasons is based on the fact that because of Earth's axis, at any given point during the year, the Northern hemisphere (half) of the Earth may be closer to the sun than the Southern Hemisphere, and vice-versa. Because the closer hemisphere is receiving more direct sunlight, they go through a period we refer to as 'Summer'. The further hemisphere, which is receiving more indirect sunlight, goes through a period we call 'Winter'

Answer 5

During the year, the seasons change depending on the amount of sunlight reaching the Earth as it revolves around the Sun. The seasons are caused as the Earth, tilted on its axis, travels in a loop around the Sun each year. Summer happens in the hemisphere tilted towards the Sun, and winter happens in the hemisphere tilted away from the Sun.
