Explain what causes day and night.
The rotation of the Earth on its axis causes day and night. As the Earth rotates, different parts of the planet are exposed to the Sun's light. When a particular area is facing towards the Sun, it experiences daylight and when it is facing away from the Sun, it experiences night. This rotation takes approximately 24 hours to complete, resulting in the cycle of day and night.
What does the Earth’s tilt have to do with the temperature on earth?
The Earth's tilt plays a significant role in determining the temperature on Earth. The Earth is tilted on its axis by approximately 23.5 degrees. This tilt is responsible for the changing seasons experienced on Earth.
When a particular hemisphere is tilted towards the Sun, that hemisphere receives more direct sunlight, leading to warmer temperatures and longer days. This results in summer in that hemisphere. In contrast, when the same hemisphere is tilted away from the Sun, it receives less direct sunlight, leading to colder temperatures and shorter days, resulting in winter.
The tilt also affects the distribution of sunlight across different latitudes, which influences the global climate patterns. Regions near the equator receive more direct sunlight throughout the year, resulting in warmer temperatures, while regions closer to the poles receive less direct sunlight, leading to colder temperatures.
Overall, the Earth's tilt plays a crucial role in determining the temperature variations and changes in seasons on Earth.
