The Sun
The second zone of the sun is called:
The radiative zone
Planets are stable due to:
Their own gravity
This type of eclipse requires protective eyewear
Solar
On Uranus, an object has a mass of 50 kg. The gravity is 4.7 m/s2. What is the object's mass on Earth?
50 kg.
The first light that ever travelled freely in the universe is called:
Cosmic Microwave Background Radiation
The Sun is mostly made of these two elements:
Hydrogen and helium
The only planet that water *may* exist on other than Earth in a usable form:
Mars
This celestial body never changes in an eclipse:
The Sun
What is the formula for calculating mass?
Mass = weight / gravity
What does GPS stand for?
Global Positioning System
What is nuclear fusion?
Hydrogen atoms smashing together to create helium
This planet has active volcanoes
Venus
The outer region of the Sun's shadow in an eclipse:
Penumbra
Why is gravity's unit of measurement m/s2 and not m/s?
m/s2 measures acceleration, m/s measures speed

Uranus
A solar eclipse occurs this often:
Once every 18 months
What is the difference between mass and weight?
Mass measures matter inside an object, weight measures gravity's force on the object
