Terjadinya siang dan malam disebabkan karena ....
Correct Answer
C. Bumi yang berputar
Explanation
The correct answer is "Bumi yang berputar". The occurrence of day and night is caused by the rotation of the Earth on its axis. As the Earth rotates, different parts of it 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 alternating periods of daylight and darkness.
2.
Bagian bumi yang paling banyak mendapatkan sinar matahari adalah ....
Correct Answer
A. Daerah katulistiwa
Explanation
The equator receives the most direct sunlight throughout the year, making it the region on Earth that receives the most sunlight. This is because the equator is located at the center of the Earth and is perpendicular to the sun's rays. As a result, the equator experiences consistently high temperatures and receives the most intense sunlight, leading to warmer climates and a higher amount of solar energy.
3.
Perputaran bumi mengelilingi matahari disebut ....
Correct Answer
D. Revolusi bumi
Explanation
The correct answer is "Revolusi bumi." Revolusi bumi refers to the rotation of the Earth around the Sun. This phenomenon takes approximately 365.25 days to complete, resulting in the change of seasons and the length of a year. The term "orbit bumi" would imply the path followed by the Earth around the Sun, while "rotasi bumi" would refer to the Earth's rotation on its axis. "Jalan bumi" does not accurately describe the Earth's movement around the Sun.
4.

Correct Answer
D. 24 jam
Explanation
The rotation of the Earth on its axis is what causes day and night. As the Earth rotates, different parts of it are exposed to the Sun's light, creating the cycle of day and night. This rotation takes approximately 24 hours, which is why we have a 24-hour day.

6.
Terjadinya pergantian tahun disebabkan oleh ....
Correct Answer
B. Revolusi bumi
Explanation
The occurrence of the change of year is caused by the revolution of the earth. This refers to the earth's movement around the sun in an elliptical orbit, which takes approximately 365.25 days to complete. As the earth revolves around the sun, different parts of the earth receive varying amounts of sunlight, leading to the change of seasons and the marking of a new year.
7.
Revolusi bumi mengakibatkab bumi bagian utara dan selatan mengalami ....
Correct Answer
C. 4 musim
Explanation
The correct answer is 4 musim. The revolution of the earth around the sun causes the northern and southern hemispheres to experience different seasons throughout the year. As the earth orbits the sun, its axis is tilted, which results in varying amounts of sunlight reaching different parts of the earth at different times. This tilt and revolution create the four seasons: spring, summer, autumn, and winter. Therefore, the revolution of the earth causes the northern and southern parts of the earth to experience four seasons.

Correct Answer
B. Terjadinya siang malam
Explanation
Perputaran bumi pada porosnya menyebabkan terjadinya siang dan malam. Ketika bumi berputar, bagian yang menghadap matahari akan mengalami siang, sementara bagian yang tidak menghadap matahari akan mengalami malam. Hal ini terjadi karena rotasi bumi mengakibatkan perubahan posisi matahari terhadap bumi sepanjang hari. Pada saat bumi berputar, bagian yang menghadap matahari akan menerima sinar matahari secara langsung, sehingga terjadi siang. Sementara itu, bagian yang tidak menghadap matahari akan mengalami kegelapan, sehingga terjadi malam.

Perhitungan tahun pada kalender masehi berdasarkan ....
Correct Answer
B. Lama waktu bumi berputar mengeliling matahari
Explanation
The calculation of years in the Gregorian calendar is based on the time it takes for the Earth to orbit around the sun. This period, known as a tropical year, is approximately 365.24 days long. By dividing this time into equal segments, we can determine the length of a year and establish a calendar system. This calculation accounts for the slight discrepancy between the actual length of a year and the standard 365 days, resulting in the addition of a leap year every four years to keep the calendar aligned with the Earth's orbit.
