929 - How do seasons affect the weather in different parts of the world?

Imagine the Earth as a big ball. As it moves around the sun, different parts of the Earth tilt towards or away from the sun throughout the year. This tilt affects how much sunlight each area gets, which changes the weather.

• When an area tilts towards the sun, it gets a lot of sunlight and becomes warm (summer).
• When an area tilts away from the sun, it gets less sunlight and becomes cold (winter).
• When an area is tilted just right, it gets a mix of sunlight and darkness, making the weather mild (spring and autumn).

Different parts of the world experience these seasons at different times because they are in opposite positions on the Earth.

For example: - When it's summer in the United States (June to August), it's winter in Australia (June to August). - When it's autumn in the United Kingdom (September to November), it's spring in New Zealand (September to November).

So, the tilt of the Earth as it moves around the sun is what causes the different seasons in different parts of the world.
