Seasons

rotation

-the spinning of the Earth on its axis
-takes 24 hours
-causes day and night

axis

-the imaginary line that passes trhough the Earth's center and the North and South poles
-imaginary line on which the Earth spins
-tilted at 23.5 degrees

revolution

-movement of one object around the other (Earth travels around the sun)
-Earth travels around the sun, takes 1 year or 365 1/4 days

orbit

-Earth's path as it revolves around the sun
-Earth's path is a flattened circle, or oval shape- called an ellipse

seasons

-caused by the Earth's tilt on its axis as it moves (revolves) around the sun

Poles

-Energy from the sun is spread out over a greater area, causes these areas to have lower temperatures
-Sunlight hits these areas at an angle because the Earth is tilted on its axis

Equator

Sunlight hits this area more directly because the Earth is tilted on its axis

summer

When the north end of Earth's axis is tilted toward the sun, the Northern Hemisphere has ________________.

winter

When it is Summer in the Northern Hemisphere it is ___________ in the Southern Hemisphere

hemisphere

-one half of the sphere that makes up Earth's surface
-North or South of the equator

summer

-(true or false)

- (shorter or longer)

direct

The hemisphere that is tilted toward the sun will recieve more ___________ rays from the sun.
- (direct or indirect)

solstice

-two days each year, when the noon sun is overhead at either 23.5 degrees south or 23.5 degrees north (longest and shortest day of the year)

equinox

-occurs half way between the solstices, when neither hemisphere is tilted toward or away from the sun (two days a year)
-means "equal night and day

morning and late afternoon

time of day when shadows will be longest

solar noon

Sun will be at its highest point for the day and also when shadow will be at its shortest during the day

Winter solstice

around December 21 in the Northern Hemisphere-shortest day of the year,marks the start of Winter

Spring equinox

around March 21 in the Northern Hemisphere marks the start of Spring

Summer solstice

around June 21 in the Northern Hemisphere-longest day of the year, marks the start of Summer

Fall equinox

around September 23 in the Northern Hemisphere, marks the start of Fall or Autumn
