How does Earth have seasons?
Because of the Earth's tilt
What causes day and night?
What's the difference between a solar eclipse and a lunar eclipse?
A Solar Eclipse is when the Moon's shadow crosses the Earth's surface.
A Lunar Eclipse is when the Earth lies between the Sun and Moon
What causes day and night is when our side where we live is facing the sun its daytime. When the Earth keeps spinning and we go on the other side its nighttime
Are sunspots cooler or hotter spots in our sun?
I think it's cooler
Yeah it's cooler cause
less gas is transferring heat from the core of the sun to the photosphere.
The Earth experiences seasons due to its axial tilt and its orbit around the Sun. To understand how this works, let's break it down step by step:
1. Axial Tilt: The Earth is tilted on its axis by about 23.5 degrees relative to its orbit around the Sun. This tilt remains constant throughout the year.
2. Orbit around the Sun: Earth revolves around the Sun in an elliptical path called its orbit. It takes approximately 365.25 days to complete one orbit.
3. Sunlight Intensity: As the Earth orbits around the Sun, different parts of the planet receive varying amounts of sunlight. When a particular hemisphere is tilted towards the Sun, it receives more direct sunlight and experiences summer. Conversely, when that hemisphere is tilted away from the Sun, it receives sunlight at a lower angle, leading to cooler temperatures and winter.
4. Solstices: The two solstices occur when the Earth's tilt is most inclined towards or away from the Sun. The summer solstice, around June 21st, marks the longest day of the year in the Northern Hemisphere and the shortest day in the Southern Hemisphere. The winter solstice, around December 21st, marks the shortest day in the Northern Hemisphere and the longest day in the Southern Hemisphere.
5. Equinoxes: The equinoxes occur when the tilt of the Earth is neither towards nor away from the Sun. These are the days when the lengths of day and night are nearly equal all over the world. The spring equinox occurs around March 21st, marking the beginning of spring in the Northern Hemisphere and autumn in the Southern Hemisphere. The autumnal equinox occurs around September 22nd, marking the beginning of autumn in the Northern Hemisphere and spring in the Southern Hemisphere.
Overall, the combination of the Earth's axial tilt and its orbit around the Sun leads to the changing seasons throughout the year.
