Geography
Imaginary line that passes through the Earth at 0 degrees latitude.
Equator
Causes the Earth to have seasons as it moves around the Sun.
The earth's tilt
The path that Earth takes in an oval shape around the Sun.
Earth's Orbit
Shortest day of the year when the hemisphere of the Earth is tilted away from the sun.
Occurs in December for the Northern Hemisphere.
Occurs in June for the Southern Hemisphere.
The Winter Solstice
Name the seasons in order starting with winter.
1. Winter
2. Spring
3. Summer
4. Fall (Autumn)
The name of the TWO halves of the Earth, split by the Equator.
Northern and Southern Hemispheres
The degree at which the Earth is always tilted at an angle as it rotates on its axis and orbits the Sun.
23.45
(23.5 or 23.4)
The imaginary lines that run around the Earth horizontally with the Equator being the 0 degree line.
Latitude
Longest day of the year when the hemisphere of the Earth is tilted towards the sun.
Occurs in June for the Northern Hemisphere.
Occurs in December for the Southern Hemisphere.
The Summer Solstice
Earth's tilt means that during winter months half the Earth receives less light and during summer months, the Earth receives more light.
The imaginary line just north of the Equator that is the furthest point north where the Sun remains directly above-head all year round. Denotes the tropic zone.
Tropic Line of Cancer
Which direction would the northern hemisphere be tilted if it is winter time in Arizona?
Away from the sun
Thermal Energy passing through the vacuum of space between the Sun and the Earth.
Radiation
When there are 12 hours of day and 12 hours of night, and it starts to get colder as the earth begins to tilt away from the sun.
The Fall Equinox
Explain what would happen if the Earth were not tilted on its axis.
No seasons. No changes in daylight throughout the year. Temperatures would remain mostly constant with cold poles and a hot equator.
The imaginary line just south of the Equator that is the furthest point south where the Sun remains directly above-head all year round. Denotes the tropic zone.
Tropic Line of Capricorn
Which direction would the southern hemisphere be tilted if it is Summer time in Arizona?
Away from the Sun
Thermal Energy passing through matter through collisions of atoms and molecules.
Conduction
When there are 12 hours of day and 12 hours of night, and it starts to get warmer as the earth begins to tilt towards the sun.
The Spring Equinox
Explain why the Earth spins on its axis and orbits the Sun.
The origination of the Sun. Creation of the solar system. Atoms, molecules bumbing into each other long ago.
