She used the same size balls for the Earth, Moon, and Sun.
She made Earth orbit the Sun.
She moved the Sun away from the Earth and Moon.

Look at this picture. Which of the following is a true statement about our solar system?
The inner planets contain the most mass.
The outer planets have circular orbits.
Each object in our solar system follows an elliptical orbit around the Sun.
The Sun captured planets from other galaxies.
Why would global temperature drop if the Earth were struck by an asteroid several km in diameter or larger?
the impact would move the Earth farther from the sun
the resulting dust cloud would block out sunlight
the ices in the asteroid would increase the light reflected by Earth
the low temperature of the asteroid would chill the oceans
One theory about how the dinosaurs went extinct is...
They caught the flu.
A large meteorite hit the Earth, and dust and debris that exploded from the crater blocked the sunlight. The plants they needed for food died.
They ate each other until they all went extinct.
An asteroid hit the Earth, knocking it on its side, and changing the seasons forever. Suddenly, the areas they lived in became very cold.
