Why wouldn’t carbon dating work to determine the age of the earth?

The half-life of carbon is too short.

Kepler's third law of planetary motion describes the relationship between the

distance from the Sun and length of year (T^2=R^3)

Why is the interior of a car parked in the summer warmer than the air around it?

Heat is trapped in the car by the glass

an object is moving away from you.

How does the greenhouse effect work?

Greenhouse gases trap the sun's energy

The big bang theory explains

how the universe, stars, and galaxies were created.

Without the greenhouse effect, the average temperature of the earth would be:

colder than current temperatures
