Which statement is true about gravity?
Gravity affects all matter on Earth.
Gravity acts only on objects that are touching.
Gravity is a force that repels one object from another.

Why do we experience the changing of seasons on the earth?
Distance from the sun: As the Earth revolves in orbit around the Sun, when we are closer to the Sun, the days are longer/warmer and when we are farther away from the Sun, the days are colder/shorter.
Rotation of the earth: As the Earth spins or rotates on its axis it results in seasonal temperature changes each day.
Change in solar output: sometimes the Sun burns hotter than other times of the year.
Tilt of the Earth's axis: the Earth's poles are either titled towards or away from the Sun at different times of the year, resulting in longer days/more direct sunlight or shorter days/less direct sunlight.
What season is it for us in Michigan when our Northern Hemisphere is tilted toward the sun?
summer
winter

The Sun is the biggest and brightest star in the universe
The Sun is the closest star to the Earth
No other stars are as big or as bright as the Sun
Locations, like Michigan, in the Northern Hemisphere are warmest in summer because sunlight in summer is
