20.1 Earth's Sunlight and Seasons

In Southern Hemisphere, when is it experiencing the winter solstice?

• Letter A: the S. Hemisphere is tilted the most towards the Sun here.

• Letter B: the S. Hemisphere experiences equal day and night here.

• Letter C: the S. Hemisphere is tilted the least away from the Sun here.

• Letter D: the S. Hemisphere is tilted the most away from the Sun here.

In the Southern Hemisphere, when is it experiencing a summer solstice?

• This is when the S. Hemisphere is tilted the most towards the Sun.

• This is when the S. Hemisphere is tilted the least towards the Sun.

• This occurs during the winter months in the Northern Hemisphere.

• This is when the Sun is directly overhead at the equator.

In the Northern Hemisphere: what position is the spring equinox?

• Position A: The Northern Hemisphere is tilted the most away from the Sun (Winter).

• Position B: The Northern Hemisphere is not tilted towards, nor away from the Sun, it is side-by-side to the Sun.

• Position C: The Northern Hemisphere is tilted towards the Sun (Summer).

• Position D: The Northern Hemisphere is in a state of complete darkness.

Which image represents summer in the southern hemisphere?

• G: the bottom of earth is tilted towards the sun

• A: the top of earth is tilted towards the sun

• B: the earth is in a circular orbit around the sun

• C: the sun is directly above the equator

During which season is there the most direct sunlight?

• Winter

• Spring

• Summer

• Autumn

Which image represents summer in the northern hemisphere?

• F: the top of earth is tilted towards the sun

• F: the earth is farthest from the sun

• F: the sun is directly overhead at the equator

• F: the top of earth is tilted away from the sun

What is an equinox?

• A time when the Earth is tilted towards the Sun, resulting in longer days and shorter nights.

• A moment when the Earth is neither tilted towards nor away from the Sun, leading to approximately equal day and night lengths.

• A period when the Sun is at its highest point in the sky, causing the longest day of the year.

• A phase of the Moon that occurs when it is fully illuminated by the Sun.

In picture 3, what season is it in the southern hemisphere?

• Spring: the earth moves counterclockwise so the last season for the south was winter, the next season will be spring, both the top and bottom of earth get equal sunlight

• Summer: the earth is tilted towards the sun, making it the warmest season in the southern hemisphere

• Autumn: the earth is transitioning from summer to winter, leading to cooler temperatures

• Winter: the earth is tilted away from the sun, resulting in the coldest season in the southern hemisphere

Why do we have different seasons in different hemispheres?

• Because the Earth is flat and has no tilt.

• When one hemisphere is tilted towards the Sun, it experiences summer, while the opposite hemisphere, tilted away, experiences winter.

• The seasons are caused by the distance of the Earth from the Sun.

• Different seasons are a result of varying atmospheric pressure in each hemisphere.
