Equinox
This is how many days it takes Earth to make one revolution:
365 and 1/4 days
The spin of an object around its axis is...
Rotation
Why do countries situated around the equator remain hot all year round?
This area of Earth receives the most direct sunlight, regardless of axial tilt
When it is Winter in the Northern Hemisphere it is ______________ in the Southern Hemisphere.
SUMMER
This is the force responsible for keeping Earth in orbit around the sun:
Gravity
Occurs when Earth's rotation axis is tilted neither towards or away from the sun. Equal day/night
Equinox
What is the longest day of the year? Choose which solstice and the date:
Summer Solstice, June 20th
In order for seasons to occur, Earth must be tilted at an angle. What is that measurement?
23.5 degrees
Name the season AND the month when Earth is technically closest to the sun in its revolution.
(nothing to do with tilt proximity)
Winter, January
Occurs when Earth's rotation axis is tilted directly towards or away from the sun
Solstice
Tell why it is colder in the Northern Hemisphere during the Winter Solstice. Include:
Tilt and sunlight in your answer
The Northern Hemisphere is tilted away from the sun during the Winter Solstice and therefore is receiving indirect sunlight that is less intense...providing less heat to the area. This is why we experience the season of Winter.
