The seasons are caused by the tilt of the Earth's rotational axis away or toward the sun as it travels through its year-long path around the sun. The Earth has a tilt of 23.5 degrees relative to the "ecliptic plane" (the imaginary surface formed by it's almost-circular path around the sun).

The seasons are caused by the tilt of the Earth's rotational axis away or toward the sun as it travels through its year-long path around the sun. The Earth has a tilt of 23.5 degrees relative to the "ecliptic plane" (the imaginary surface formed by it's almost-circular path around the sun).

The answer is "Earth's seasons."

The seasons are caused by the tilt of the Earth's rotational axis away or toward the sun as it travels through its year-long path around the sun. The Earth has a tilt of 23.5 degrees relative to the "ecliptic plane" (the imaginary surface formed by it's almost-circular path around the sun).

The answer is none of these. The answer choices describe the winter solstice.

The day that the Earth's North Pole is tilted closest to the sun is called the summer solstice. It is also the day that the Sun reaches its highest point in the sky. The winter solstice, or the shortest day of the year, happens when the Earth's North Pole is tilted farthest from the Sun.

The answer is "position 2" because the sun's rays are indirectly hitting the surface in the southern hemisphere. Positions 1 and 3 are fall and spring in the southern hemisphere respectively.

The answer is "position 4" because the sun's rays are indirectly hitting the surface in the southern hemisphere. Positions 1 and 3 are spring and fall in the northern hemisphere. 

The seasons are caused by the tilt of the Earth's rotational axis away or toward the sun as it travels through its year-long path around the sun. The Earth has a tilt of 23.5 degrees relative to the "ecliptic plane" (the imaginary surface formed by it's almost-circular path around the sun). The day that the Earth's North Pole is tilted closest to the sun is called the summer solstice. It is also the day that the Sun reaches its highest point in the sky. The winter solstice, or the shortest day of the year, happens when the Earth's North Pole is tilted farthest from the Sun.

The answer is "Alaska is located in the far northern hemisphere, away from the sun in spring, and day and night are caused by Earth's rotation."

The Earth has a tilt of 23.5 degrees relative to the "ecliptic plane" (the imaginary surface formed by it's almost-circular path around the sun).

The answer is "Earth's rotation causes day and night, not the seasons."

The seasons are caused by the tilt of the Earth's rotational axis away or toward the sun as it travels through its year-long path around the sun. The Earth has a tilt of 23.5 degrees relative to the "ecliptic plane" (the imaginary surface formed by it's almost-circular path around the sun).
