define the vocab word
gravity
All bodies with mass exert a force that pulls objects with mass towards them
How are craters made?
Rocks from space hit the moon.
What is the darkest part of a shadow during an eclipse?

When the North Pole and Northern Hemisphere are tilted toward the sun, what is happening in the south pole and southern Hemisphere?
the South Pole and Southern Hemisphere are tilted away from the sun
Why is the temperature near the equator hot, and the temperature near the Poles cold?
The rays move from the sun to Earth in a direct path. The sunlight is less concentrated at the Poles as it is at the equator due to the tilt and shape of the earth. The heat they receive is not enough to melt the ice and warm the oceans and land.
what does the earth's revolution cause and what does the earth's rotation cause?
revolution creates Earth's year and its seasons
rotation in conjunction with sunlight causes day and night
If the sun has a greater gravitational pull than earth does, why does the moon orbit the earth instead of the sun?
The moon is closer to the earth than the sun. The moon is therefore pulled into the gravitational pull of the earth as it has more mass and more gravity than the moon.
Describe how a waxing crescent moon looks. what is the change in the moons appearance called?
C-shaped and getting bigger
moon phase
Describe what happens during a solar eclipse.
The moon passes directly between the sun and the earth, briefly blocking out the sun.
what is the earth's tilt and how is Earth's movement in space related to the seasons?
The earth's axis is tilted approximately 23.5°. This tilt, the earth's revolution around the sun, and Earth's spherical shape are what create the four seasons.
When does summer begin in the southern hemisphere?
in the Southern Hemisphere, summer begins in December
how long does one rotation take; one revolution take?
one rotation takes 24 hours
one rotation takes 365.25 days, one calendar year and every 4th year a leap year to make up for the .25 hours over the 4 years
why can we still see Neil Armstrong's footprints on the moon?
The moon does not have an atmosphere so it does not have weather. Without weather there is no wind erosion. There is also no water to cause water erosion. Therefore the surface of the moon is only changed by craters hitting it.
Describe how a waxing gibbous moon looks
It is almost a full moon but not quite, and it is getting bigger
Describe what happens during a lunar eclipse.
