Astronomy and Celestial Phenomena

When it is summer in the Northern Hemisphere, the Earth's tilt causes the Northern Hemisphere to lean toward the sun, so the direct rays hit above the equator.

Because the Earth is tilted, the sun's rays hit different latitudes at different angles throughout the year, causing uneven heating and the change of seasons.

Seasons are primarily caused by the 23.5-degree tilt of the Earth's axis as it orbits the sun, which changes the angle and duration of sunlight received by different hemispheres.

Day and night occur because the Earth rotates on its axis, exposing different parts of the planet to the sun's light at different times.

After the full moon, the moon begins waning (shrinking). The waning gibbous phase comes after the full moon as the illuminated portion decreases toward the last quarter. The options 'New moon' and 'Waxing gibbous' are incorrect because waxing means growing. Option D has a typo (wanning instead of waning) but is the correct phase.

The lunar cycle is approximately 29.5 days. A full moon occurs roughly halfway through the cycle, about 14 to 15 days after a new moon.

When the North Pole is tilted toward the sun, the Northern Hemisphere receives more direct sunlight for longer periods, resulting in summer. The tilt of the Earth's axis is the primary driver of seasonal changes.

Earth's rotation on its axis causes the cycle of day and night, sunrise and sunset, and affects global wind patterns via the Coriolis effect. Seasons are caused by the Earth's axial tilt and its revolution around the sun, not its rotation.

Earth takes approximately 365.25 days to complete one orbit around the Sun. This extra quarter day is why we add a leap day every four years.

The seasons are caused by the 23.5-degree tilt of the Earth's axis as it orbits the Sun, which changes the angle and duration of sunlight hitting different hemispheres.

A revolution is the movement of one object around another. Earth's revolution around the sun takes approximately 365 days, or one year.

The day and night cycle is caused by the Earth rotating on its axis, which takes about 24 hours.

Revolution refers to the orbital motion of one body around another. Earth revolves around the sun.
