Terjadinya siang dan malam disebabkan oleh ....
Correct Answer
B. Rotasi bumi
Explanation
The occurrence of day and night is caused by the rotation of the Earth. As the Earth rotates on its axis, different parts of the planet are exposed to the Sun's light, creating the cycle of day and night. This rotation takes approximately 24 hours to complete, resulting in the familiar pattern of alternating periods of light and darkness. The revolution of the Earth around the Sun (referred to as its orbit) also plays a role in the changing seasons, but it is the rotation that directly causes the occurrence of day and night.

Bagian bumi utara dan selatan memiliki perbedaan musim, hal ini disebabkan karena ....
Correct Answer
B. Bagian bumi utara dan selatan bumi bergantian menghadap matahari
Explanation
The correct answer is that the northern and southern parts of the Earth alternate in facing the sun. This is the main reason for the difference in seasons between the two regions. As the Earth orbits the sun, its axis is tilted, causing different parts of the Earth to receive varying amounts of sunlight throughout the year. When one hemisphere is tilted towards the sun, it experiences summer, while the other hemisphere, tilted away from the sun, experiences winter. This tilt and the resulting change in the angle of sunlight is what causes the seasons.

During the period from March 21 to June 21, the Northern Hemisphere experiences spring, while the Southern Hemisphere experiences autumn. This is because the Earth's axis is tilted, causing different parts of the planet to receive varying amounts of sunlight throughout the year. During this specific period, the Northern Hemisphere is tilted towards the sun, resulting in longer days and warmer temperatures, leading to the arrival of spring. On the other hand, the Southern Hemisphere is tilted away from the sun, resulting in shorter days and cooler temperatures, leading to the arrival of autumn.
