Explain what happens as someone goes sky diving; do they go faster when they jump out of the plane or do they get faster as they get closer to Earth.
As an object gets closer to the Earth, the gravity gets greater, so they begin to fall faster.

Why is Venus considered the hottest planet in the Solar System?
Venus has a tremendous Greenhouse Effect – Due to a large amount of carbon dioxide in the atmosphere (98%) -the CO2 traps the heat and causes the surface temperature to reach around 700 Fahrenheit.
