Earth's seasons are caused by its varying distance from the Sun throughout its orbit.
Answer: False
Explanation: This statement is incorrect. Earth's seasons are primarily caused by the tilt of its rotational axis relative to its orbital plane, not by variations in its distance from the Sun.
What is the primary reason Earth experiences seasons?
Answer: The tilt of Earth's axis of rotation relative to its orbital plane.
Explanation: The primary driver of Earth's seasons is the axial tilt of approximately 23.44 degrees, which causes different hemispheres to receive varying amounts of direct solar radiation throughout the year.
A solstice is an event occurring annually when the Sun reaches its northernmost or southernmost extreme point relative to the celestial equator.

The word 'solstice' is derived from Latin roots meaning 'sun' and 'stand still'.

Due to the precession of the equinoxes, the Sun is currently in the constellation Cancer during the June solstice.
Answer: False
Explanation: This statement is false. Due to the precession of the equinoxes, the Sun is currently associated with the constellation Taurus during the June solstice, not Cancer.
The June solstice has always been associated with the constellation Cancer due to Earth's axial tilt.
Answer: False
Explanation: This statement is false. While Earth's axial tilt is fundamental to solstices, the association of the June solstice with the constellation Cancer has shifted over millennia due to the precession of the equinoxes, and it is now associated with Taurus.
What is the current astrological constellation associated with the June solstice, and why has it changed from historical associations?
Answer: Taurus, due to the precession of the equinoxes.
Explanation: Due to the precession of the equinoxes, the June solstice, historically associated with Cancer, is now aligned with the constellation Taurus. This slow wobble of Earth's axis causes the apparent position of the Sun against the background stars to shift over millennia.
Over millennia, the June solstice has shifted from being associated with the constellation Cancer to which constellation?
Answer: Taurus
Explanation: Due to the precession of the equinoxes, the June solstice, which was once aligned with Cancer, has shifted and is now associated with the constellation Taurus.
