How Sun and Earth Interact:

How Sun and Earth Interact Can you Explain what causes the apparent movement of stars, planets, and the sun in Earth’s sky? Describe how hours of sunlight, time of sunset and sunrise change during the year? Describe position of the sun in Springfield in winter versus summer skies? Describe the position of sunrise/sunset in winter versus summer skies? Describe why the sun is never directly overhead when observed from Springfield? Describe how axial tilt affect light intensity on different parts of the Earth resulting in the seasons?

An object that orbits a star, is large enough to have become rounded by its own gravity:

An object that orbits a star, is large enough to have become rounded by its own gravity planet

A body that orbits a planet:

A body that orbits a planet satellite

A giant ball of hot gas:

A giant ball of hot gas star

Two main gases that make up stars:

Two main gases that make up stars Hydrogen and helium

An imaginary line that passes through a planet’s center and its north or south pole about which a planet rotates.:

An imaginary line that passes through a planet’s center and its north or south pole about which a planet rotates. axis

The spinning motion of a planet on its axis:

The spinning motion of a planet on its axis rotation

What causes objects in the sky (planets, stars) to appear to move across the sky?:

What causes objects in the sky (planets, stars) to appear to move across the sky? The rotation of the Earth

The two main movements of Earth through space are:

The two main movements of Earth through space are Rotation and revolution

The movement of an object around another object:

The movement of an object around another object revolution

The path of an object as it revolves around another object in space:

The path of an object as it revolves around another object in space orbit

Why does the Earth have seasons?:

Why does the Earth have seasons? The tilt of the Earth’s axis in relationship to the sun causes the intensity of the sun’s rays over different parts of the Earth to change

Either of the two days of the year on which the sun reaches its greatest distance North or South of the equator:

Either of the two days of the year on which the sun reaches its greatest distance North or South of the equator solstice

Either of the two days of the year on which neither hemisphere is tilted toward or away from the sun:

Either of the two days of the year on which neither hemisphere is tilted toward or away from the sun equinox

How does the sun’s noon time position in the sky in Springfield differ in winter versus summer?:

How does the sun’s noon time position in the sky in Springfield differ in winter versus summer? The sun is higher in the sky is summer and is lower in the southern sky in the winter.

At what time of year at noon in Springfield will the shadow of the tree be longer?:

At what time of year at noon in Springfield will the shadow of the tree be longer? Shadow of the tree will be longer in winter because the sun is lower in southern sky.

Why is the sun never directly overhead during the day in Springfield?:

Why is the sun never directly overhead during the day in Springfield? The sun never gets farther north than 23.5 degrees. Springfield is at about 37 degrees north latitude.

From the previous slide, what dates are the solstices and equinoxes for Springfield?:

From the previous slide, what dates are the solstices and equinoxes for Springfield? Winter solstice About December 21 Spring equinox About March 21 Summer stolstice About June 21 Fall equinox About September 21

PowerPoint Presentation:

Earth in Space Solstices and Equinoxes The diagrams show the apparent path of the sun at the solstices and equinoxes in the Northern Hemisphere. What is the sun’s path at the equinoxes and the December solstice for the Southern Hemisphere?

From the previous slide, explain the difference in position of the sunrise in winter compared to summer.:

From the previous slide, explain the difference in position of the sunrise in winter compared to summer. Winter sunrise is in the southeast sky and summer sunrise is in the northeast sky.
