Transcript of The Seasons

Earth's Rotation
The spinning of the Earth on its axis.
The Earth spins counterclockwise.
One rotation takes 24 hours.
This causes day and night

Earth's Revolution
The movement of the Earth in its orbit around the sun.
It takes 365 ¼ days (1 year) for one revolution.
The Earth orbits (revolves) the sun in a counterclockwise direction.

Seasons are caused by the tilt of the Earth as it revolves around the Sun.

The earth is tilted 23 ½° on it’s axis.

This is also the reason that the Southern Hemisphere has opposite seasons than the Northern Hemisphere.

Cause of the Seasons
The angle of insolation is the angle at which the sun’s rays strike a particular location on Earth.

INcoming SOLar radiATION

This affects us daily as well as seasonally.

Angle of Insolation
Summer is warmer than winter because the sun is at a higher angle of insolation (more direct).

The sun can be directly overhead in the tropics during winter and summer.

The sun is directly over the equator in the beginning of spring and fall.

Seasons and Angle of Insolation
March 20th or 21st: Spring Equinox (Northern Hemisphere)

Equal day and night
Equinox means "Equal Night" in Latin.

Days begin to be longer and nights shorter.

Sun is directly over the equator.

June 21st or 22nd : Summer Solstice (Northern Hemisphere)

Longest day of the year for us.
Sun is directly over the Tropic of Cancer
Solstice mean "To stand still" in Latin.
North of the Arctic Circle has 24 hours of daylight.

September 22nd or 23rd: Autumnal Equinox (Northern Hemisphere)

Equal day and night

Days begin to be shorter and nights longer.

Sun is directly over the equator.

December 21st or 22nd: Winter Solstice (Northern Hemisphere)

Shortest day of the year.

Sun is directly over the Tropic of Capricorn.
South of the Antarctic Circle has 24 hours of daylight.

Moon Phases
As the moon revolves around the Earth, the amount of sunlight on the side of the moon that faces the Earth changes.

The different appearances of the moon due to its changing positions are called the moon phases.

It takes about 27 days for the moon to revolve around the Earth.

The sun, the moon and the rotation of the earth are the major forces involved in creating the tides
The Moon's gravitational forces are strong enough to cause the water levels to 'bulge.'
As the Moon orbits our planet and as the Earth rotates, the bulge also moves.
The areas of the Earth where the bulging occurs experience high tide, and the other areas are subject to a low tide.
Spring Tide
: a tide that occurs during full or new moons. The average tidal ranges are slightly larger. This occurs twice each month.
It has nothing to do with the Spring season.
Spring tide animation: http://oceanservice.noaa.gov/facts/springtide.html

Neap Tide
: A tide that occurs when the difference between high and low tide is least; the lowest level of high tide. Neap tide comes twice a month, in the first and third quarters of the moon.

Spring and Neap tide animation:
Lunar eclipses occur when Earth's shadow blocks the sun's light, which otherwise reflects off the moon.
Solar eclipses occur when the Moon blocks the light of the Sun on Earth. The moon casts a small shadow on Earth.
