CSEE (Form 4) Solar System — practice questions

1. The Earth's orbit is not a perfect circle, so its distance from the Sun varies through the year. 2. The position closest to the Sun is called perihelion. 3. Aphelion is the opposite: the point at which the body is farthest from the Sun. 4. An equinox is the moment when day and night are of equal length, on 21 March and 23 September each year. 5. Sunrise and sunset are effects of the Earth's rotation, not of its revolution around the Sun. _Source: NECTA CSEE 2023 Geography 013, Question 1: Multiple Choice Questions, item (i)_

1. An equinox is the moment when day and night are of equal length everywhere. 2. This happens twice a year, as the Earth revolves around the Sun. 3. Those two moments fall on 21 March and 23 September. 4. They are effects of the Earth's revolution, along with perihelion and aphelion. 5. Sunrise and sunset, by contrast, result from the Earth's rotation on its own axis. _Source: NECTA CSEE 2023 Geography 013, Question 1: Multiple Choice Questions, item (i)_
