Here's how it works:
* Earth's Tilt: The Earth is tilted on its axis at approximately 23.5 degrees. This tilt means that different parts of the Earth receive varying amounts of sunlight throughout the year.
* Summer Solstice: During the summer solstice (around June 21st in the Northern Hemisphere), the Northern Hemisphere is tilted towards the sun, receiving the most direct sunlight and experiencing longer days. This leads to warmer temperatures.
* Winter Solstice: During the winter solstice (around December 21st in the Northern Hemisphere), the Northern Hemisphere is tilted away from the sun, receiving less direct sunlight and experiencing shorter days. This results in colder temperatures.
* Equinoxes: The spring and fall equinoxes (around March 20th and September 22nd) mark the transition periods when the Northern Hemisphere is neither tilted towards nor away from the sun, resulting in nearly equal day and night lengths.
Impact on North America:
North America is located in the Northern Hemisphere, and the tilt of the Earth's axis causes these seasonal changes:
* Spring: Temperatures rise, snow melts, and plants begin to grow.
* Summer: Temperatures are warmest, with long days and abundant sunlight.
* Fall: Temperatures cool, leaves change color, and precipitation increases.
* Winter: Temperatures are coldest, with short days and snowfall in many regions.
Key takeaway: It's the Earth's tilt and its journey around the sun that drive the four seasons, creating distinct weather patterns and experiences throughout the year.
