The spinning of the Earth on it's axis
Rotation
The elliptical path the Earth takes to travel around the Sun.
Orbit or revolution
What galaxy to we reside in?
The milky way
Earth is part of this group of planets
Inner planets or terrestrial planets
Name the planets in order from closest to the Sun to farthest.
Mercury, Venus,Earth, Mars, Jupiter, Saturn, Uranus, Neptune.
The direction that the earth rotates
Counter-clockwise (objects appear to move east to west)
At these times of year (Seasons) the sunlight shines equally on the northern and southern hemispheres.
Spring and Fall
The two things that are provided by our star, the Sun.
What are heat and light?
The barrier that separates the terrestrial planets from the gas giants.
Asteroid belt
One the SUN
The length of time that it takes Earth to rotate.
24 hours about 12 hours of day and 12 hours of night.
In this season the Northern Hemisphere is tilted towards the sun, causing longer daylight hours and more direct sunlight.
Summer
What is the most massive planet in our solar system?
Jupiter
What is the only other planet in our solar system that we believe could sustain life?
Traits that tell if object is a planet
The object has to be round, orbit around a star, and have enough gravity to clear other objects from its orbit.
What phase of the moon is shown here?
New Moon
This part of the Earth gets the most direct light from the sun and has the least variation in daylight hours. It is also the region of the world with the most rainforests.
The Equator
The terms used to describe the moon when it appears to grow bigger and when it appears to get smaller.
Waxing is growing and waning is shrinking
How many planets are in our solar system? Include Earth
8
The reasons why stars appear brighter than others
They are closer or larger or give off more light energy.
Explain why the moon appears to change shape in the night.
The moon appears to change because of the amount of light it reflects as it orbits the Earth. It takes about 28 days to complete a revolution and you will see 8 different phases of the moon.
1. Length of day and night
2. Seasons
3. Star patterns
The Earth's rotation is the reason we have this.
What is day and night?
The relationship between a meteoroid, a meteor and a meteorite.
Meteoroid is floating in space, the meteor is traveling through Earth's atmosphere and a meteorite has made it to the surface (land).
Four other main objects found in our solar system.
Comets, asteroids, meteors, dwarf planets
