What day of the year marks the start of the fall season in the Northern Hemisphere when day and night are both about 12 hours each? 

• summer solstice
• winter solstice
• vernal equinox
• autumnal equinox

The Earth's tilt is 23.5 degrees. Predict the climate change if the tilt 0 degrees.

• Southern Hemisphere summers would be longer in duration.

• Northern Hemisphere summers would be cooler in temperature.

• Earth would not have seasons.

• It would not affect earth's climate.

What causes Earth's seasons?

• The Earth has seasons because the temperature of the sun changes.

• The Earth has seasons because of Earth's distance from the Sun

• The Earth has seasons because Earth’s axis is tilted as it revolves around the sun.

• The Earth has seasons because of Earth rotation on its axis.

According to the diagram, on the first day of FALL in the southern hemisphere, which of the following is TRUE?

• The North Pole is not tilted toward or away from the Sun.

• The North Pole is tilted 12.25ᵒ toward the Sun.

• The North Pole is tilted 23.5ᵒ toward the Sun.

• The North Pole is tilted 23.5ᵒ away from the Sun.

According to the diagram, on the first day of WINTER in the northern hemisphere, which of the following is TRUE?

• The North Pole is not tilted toward or away from the Sun.

• The North Pole is tilted 12.25ᵒ toward the Sun.

• The North Pole is tilted 23.5ᵒ toward the Sun.

• The North Pole is tilted 23.5ᵒ away from the Sun.

When the south pole of the Earth’s axis is tilted toward the sun, explain the sun’s effect on South America.

• South America will experience more direct rays and longer days.

• South America will experience more direct rays and shorter days.

• South America will experience more indirect rays and longer days.

• South America will experience more indirect rays and shorter days.

When the north end of the Earth’s axis is tilted away the sun, explain the sun’s effect on the North America. 

• North America will experience more direct rays and longer days.
• North America will experience more direct rays and shorter days.
• North America will experience more indirect rays and longer days.
• North America will experience more indirect rays and shorter days.

Using the diagram, explain what is occurring between the Earth, Sun and Moon. 

• A first quarter moon is occurring because it is at a right angle from the Earth.
• A solar eclipse is occurring because the moon must be blocking some of the sunlight to be considered an eclipse
• A lunar eclipse is occurring because the Earth must be blocking some of the sunlight to be considered an eclipse.
• A full moon is occurring for the Earth because the sun is shining directly on the moon.

Where on Earth would a student need to be standing in order to experience a total eclipse? 

• A student would experience a total eclipse on the side of the Earth that is facing away from the sun.
• A student would experience a total eclipse at either of the poles on the Earth.
• A student would experience a total eclipse in the umbra region because it is a complete shadow of the sun.
• A student would experience a total eclipse in the penumbra region because it is a shadow of the sun.

The diagram shows different positions of the moon relative to Earth and the sun. In which phase will an observer on Earth see a waxing gibbous moon?

• phase A

• phase B

• phase C

• phase D
