Where is the Earth tilted in relation to the Sun from June to September?

Where is the Earth tilted in relation to the Sun from December to March?

Where is the Earth tilted in relation to the Sun from September to December?

Where is the Earth tilted in relation to the Sun from March to June?

The reason for _____ in the Northern Hemisphere and _____ in the Southern Hemisphere is because Earth’s tilt is sideways to the sun, and hours of daylight and darkness are the same in both hemispheres on about September 22.

The reason for _____ in the Northern Hemisphere and _____ in the Southern Hemisphere is because the North Pole is tilted almost directly toward the sun on about June 21.

The reason for _____ in the Northern Hemisphere and _____ in the Southern Hemisphere is because the South Pole is tilted almost directly toward the sun on about December 21.

The reason for _____ in the Northern Hemisphere and _____ in the Southern Hemisphere is because Earth’s tilt is sideways to the sun, and hours of daylight and darkness are the same in both hemispheres on about March 20.

The total amount of sunlight that approaches Earth is _____ in June as in December.

What is the correct order of the moon phases?

The moon is moving toward the full moon phase, and presently more than a quarter of it is visible on Earth.

The moon has moved eastward in its orbit from the new moon phase and forms a 90o angle with the sun and Earth, and the moon appears half bright and half. dark

The moon, sun, and Earth are forming a 90o angle, so the side of the moon facing Earth is half dark and half bright. The visible part of the moon will be getting smaller as it moves toward the new moon phase.

More than a quarter of the moon is visible, and the visible portion is becoming smaller as the moon moves toward the third quarter phase.

The moon, the sun, and Earth are in a straight line, the side of the moon facing Earth is completely visible.

Although less than a quarter of the moon is visible now, the visible portion is getting larger as the moon facing Earth is bright and visible.

Less than a quarter of the moon is visible, and the visible part is getting even smaller as the moon moves toward the new moon phase.

The moon lies between the sun and Earth so the side of the moon facing Earth is dark and the moon is not visible.
